146-410: The original bridge was constructed in 1880. It had two swing spans as the lock of a nearby dam was in the process of being moved from the west to east side. That bridge was wrecked by the 1884 flood. A second bridge was built on the same piers, also with two swing spans. An increase in traffic necessitated a new bridge in 1900, which was built on 4 new stone piers with a single swing section. That bridge

292-419: A fish ladder are often taken to counteract this. Navigation locks have also potential to be operated as fishways to provide increased access for a range of biota. Locks can be built side by side on the same waterway. This is variously called doubling , pairing , or twinning . The Panama Canal has three sets of double locks. Doubling gives advantages in speed, avoiding hold-ups at busy times and increasing

438-498: A topographic point of view, superimposed and replaced by the Roman one. The Roman city was then gradually superimposed and replaced by the medieval one. The urban center of Milan has therefore grown constantly and rapidly, until modern times, around the first Celtic nucleus. The original Celtic toponym Medhelanon then changed, as evidenced by a graffiti in Celtic language present on a section of

584-725: A Council ( Consiglio ) and a President, elected contextually to the city Mayor. The urban organisation is governed by the Italian Constitution (art. 114), the Municipal Statute and several laws, notably the Legislative Decree 267/2000 or Unified Text on Local Administration ( Testo Unico degli Enti Locali ). After the 2016 administrative reform, the Borough Councils have the power to advise the Mayor with nonbinding opinions on

730-524: A Japanese garden and a public library. The Montanelli gardens, created in the 18th century, hosts the Natural History Museum of Milan and a planetarium . Slightly away from the city centre, heading east, Forlanini Park is characterised by a large pond and a few preserved shacks which remind of the area's agricultural past. In recent years Milan's authorities pledged to develop its green areas: they planned to create twenty new urban parks and extend

876-555: A boat in a lock. One incident, which took place in June 1873 on the Chesapeake and Ohio Canal, involved the boat the Henry C. Flagg and its drunk captain. That boat was already leaking; the crew, having partially pumped the water out, entered Lock 74, moving in front of another boat. Because they failed to snub the boat, it crashed into and knocked out the downstream gates. The outrush of water from

1022-464: A boat in the lock. A 200-ton boat moving at a few miles an hour could destroy the lock gate. To prevent this, a rope was wound around the snubbing post as the boat entered the lock. Pulling on the rope slowed the boat, due to the friction of the rope against the post. A rope 2 + 1 ⁄ 2 inches (6.4 cm) in diameter and about 60 feet (18 meters) long was typically used on the Erie Canal to snub

1168-500: A boat travelling upstream, the process is reversed; the boat enters the empty lock, and then the chamber is filled by opening a valve that allows water to enter the chamber from the upper level. The whole operation will usually take between 10 and 20 minutes, depending on the size of the lock and whether the water in the lock was originally set at the boat's level. Boaters approaching a lock are usually pleased to meet another boat coming towards them, because this boat will have just exited

1314-604: A bomb exploded at the National Agrarian Bank in Piazza Fontana, killing 17 people and injuring 88. In the 1980s, with the international success of Milanese houses (like Armani , Prada , Versace , Moschino and Dolce & Gabbana ), Milan became one of the world's fashion capitals. The city saw also a marked rise in international tourism , notably from America and Japan, while the stock exchange increased its market capitalisation more than five-fold. This period led

1460-528: A broad canal for more than one boat to be in a staircase at the same time, but managing this without waste of water requires expertise. On English canals, a staircase of more than two chambers is usually staffed: the lockkeepers at Bingley (looking after both the "5-rise" and the "3-rise") ensure that there are no untoward events and that boats are moved through as speedily and efficiently as possible. Such expertise permits miracles of boat balletics: boats travelling in opposite directions can pass each other halfway up

1606-527: A donkey backward through the city until getting out. Frederick I Barbarossa brought the destruction of much of Milan in 1162. A period of peace followed and Milan prospered as a centre of trade due to its geographical position. During this time, the city was considered one of the largest European cities. As a result of the independence that the Lombard cities gained in the Peace of Constance in 1183, Milan returned to

1752-426: A flight of locks is simply a series of locks in close-enough proximity to be identified as a single group. For many reasons, a flight of locks is preferable to the same number of locks spread more widely: crews are put ashore and picked up once, rather than multiple times; transition involves a concentrated burst of effort, rather than a continually interrupted journey; a lock keeper may be stationed to help crews through

1898-412: A gate, or pair of half-gates, traditionally made of oak or elm but now usually made of steel ). The most common arrangement, usually called miter gates , was invented by Leonardo da Vinci sometime around the late 15th century. On the old Erie Canal , there was a danger of injury when operating the paddles: water, on reaching a certain position, would push the paddles with a force which could tear

2044-609: A huge consensus and to pressure the monarchy to forge an alliance with the new French Empire of Napoleon III to defeat Austria and establish a large Italian state in the region. At the Battle of Solferino in 1859 French and Italian troops heavily defeated the Austrians that retreated under the Quadrilateral line . Following this battle, Milan and the rest of Lombardy were incorporated into Piedmont-Sardinia, which then proceeded to annex all

2190-423: A large complex of imperial palaces and other services and buildings of which few visible traces remain. Maximian increased the city area to 375 acres by surrounding it with a new, larger stone wall (about 4.5 km long) with many 24-sided towers. The monumental area had twin towers; the one included later in the construction of the convent of San Maurizio Maggiore remains 16.6 m high. It was from Mediolanum that

2336-412: A large spectrum of topics and are responsible for running most local services, such as schools, social services, waste collection, roads, parks, libraries and local commerce; in addition they are supplied with an autonomous funding to finance local activities. Milan is the capital of the eponymous Metropolitan city . According to the last governmental dispositions concerning administrative reorganisation,

2482-435: A lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock , a boat lift , or on a canal inclined plane , it is the chamber itself (usually then called a caisson ) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. A pound lock

2628-421: A lock. To help boats traveling downstream exit a lock, the locksman would sometimes open the paddles to create a swell, which would help "flush" the boat out of the lock. A boatsman might ask for a back swell, that is, to open and shut the paddles a few times to create some waves, to help him get off the bank where he was stuck. If boats ran aground (from being overloaded) they sometimes asked passing crews to tell

2774-460: A much larger site in Rho . The long decline in traditional manufacturing has been overshadowed by a great expansion of publishing, finance, banking, fashion design, information technology, logistics and tourism. The city's decades-long population decline seems to have partially reverted in recent years, as the comune gained about 100,000 new residents since the last census. The successful re-branding of

2920-512: A nearly two-fold increase in population. In the 1950s and 1960s, a strong demand for new residential and commercial areas drove to extreme urban expansion, that has produced some of the major milestones in the city's architectural history, including Gio Ponti 's Pirelli Tower (1956–60), Velasca Tower (1956–58), and the creation of brand new residential satellite towns, as well as huge amounts of low-quality public housings. In recent years, de-industrialization, urban decay and gentrification led to

3066-430: A population estimated at 3,196,825, with a resulting density of 2,029 inhabitants per square kilometre (5,260/sq mi). A larger urban area, comprising parts of the provinces of Milan, Monza e Brianza, Como, Lecco and Varese is 1,891 square kilometres (730 sq mi) wide and has a population of 5.27 million with a density of 2,783 inhabitants per square kilometre (7,210/sq mi). The concentric layout of

3212-446: A population of about 1.4 million, while its metropolitan city has 3.22 million residents. The urban area of Milan is the fourth-most-populous in the EU with 6.17 million inhabitants. According to national sources, the population within the wider Milan metropolitan area (also known as Greater Milan) is estimated between 7.5 million and 8.2 million, making it by far

3358-430: A short way into the chamber from below the upper gates. Allowing the rear of the boat to "hang" on the cill is the main danger when descending a lock, and the position of the forward edge of the cill is usually marked on the lock side by a white line. The edge of the cill is usually curved, protruding less in the center than at the edges. In some locks, there is a piece of oak about 9 in (23 cm) thick which protects

3504-480: A staircase lock can be used as an emergency dry dock). To avoid these mishaps, it is usual to have the whole staircase empty before starting to descend, or full before starting to ascend, apart from the initial chamber. One striking difference in using a staircase of either type (compared with a single lock, or a flight) is the best sequence for letting boats through. In a single lock (or a flight with room for boats to pass) boats should ideally alternate in direction. In

3650-404: A staircase, however, it is quicker for a boat to follow a previous one going in the same direction. Partly for this reason staircase locks such as Grindley Brook, Foxton, Watford and Bratch are supervised by lockkeepers, at least during the main cruising season, they normally try to alternate as many boats up, followed by down as there are chambers in the flight. As with a flight, it is possible on

3796-454: A swell to anyone to help them on the way, but some would ask for money for the swell. The Erie Canal management did not like swelling for two reasons. First, it used too much water lowering the water on the pound above sometimes causing boats to run aground. In addition, it raised the water level on the pound below, causing some boats to strike bridges or get stuck. On horse-drawn and mule-drawn canals, snubbing posts were used to slow or stop

3942-658: A theatre and an amphitheatre (129.5 x 109.3 m), the third largest in Roman Italy after the Colosseum in Rome and the vast amphitheatre in Capua . A large stone wall encircled the city in Caesar's time, and later was expanded in the late third century AD, by Maximian . Maximian built several gigantic monuments including the large circus (470 × 85 metres) and the thermae or Baths of Hercules ,

4088-515: A vast urban renewal of former industrial areas, that have been transformed into modern residential and financial districts, notably Porta Nuova in downtown Milan and FieraMilano in the suburb of Rho . In addition, the old exhibition area is being completely reshaped according to the Citylife regeneration project, featuring residencial areas, museums, an urban park and three skyscrapers designed by international architects, and after whom they are named:

4234-833: Is a covered passage with a glass and cast iron roof, inspired by the Burlington Arcade in London. Several other arcades such as the Galleria del Corso , built between 1923 and 1931, complement it. Another late-19th-century eclectic monument in the city is the Cimitero Monumentale graveyard, built in a Neo-Romanesque style between 1863 and 1866. The tumultuous period of early 20th century brought several, radical innovations in Milanese architecture. Art Nouveau , also known as Liberty in Italy,

4380-426: Is a normal top gate, and the intermediate gates are all as tall as the bottom gate). As there is no intermediate pound, a chamber can only be filled by emptying the one above, or emptied by filling the one below: thus the whole staircase has to be full of water (except for the bottom chamber) before a boat starts to ascend, or empty (except for the top chamber) before a boat starts to descend. In an "apparent" staircase

4526-482: Is also a well-known centre for artists. Milan features a mid-latitude, four-season humid subtropical climate ( Cfa ), according to the Köppen climate classification . Milan's climate is similar to much of Northern Italy's inland plains, with hot, humid summers and cold, foggy winters.

In the spring, gale-force windstorms may happen, generated either by Tramontane blowing from the Alps or by Bora -like winds from the north. Due to its geographic location surrounded by mountains on 3 sides, Milan

5110-480: Is more likely to be accompanied by thunderstorms and hail . Springs and autumns are generally pleasant, with temperatures ranging between 10 and 20 °C (50 and 68 °F); these seasons are characterized by higher rainfall, especially in April and May.

5256-626: Is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock . Pound locks were first used in China during the Song dynasty (960–1279 CE), having been pioneered by the Song politician and naval engineer Qiao Weiyue in 984. They replaced earlier double slipways that had caused trouble and are mentioned by

Each Borough Council is governed by

5548-443: Is only a staircase if successive lock chambers share a gate (i.e. do not have separate top and bottom gates with a pound between them). Most flights are not staircases, because each chamber is a separate lock (with its own upper and lower gates), there is a navigable pound (however short) between each pair of locks, and the locks are operated in the conventional way. However, some flights include (or consist entirely of) staircases. On

Constantine was in Mediolanum to celebrate the wedding of his sister to the Eastern Emperor, Licinius . In 402, the Visigoths besieged the city and the Emperor Honorius moved

6570-470: The Grand Union . Operation of a staircase is more involved than a flight. Inexperienced boaters may find operating staircase locks difficult. The key worries (apart from simply being paralysed with indecision) are either sending down more water than the lower chambers can cope with (flooding the towpath, or sending a wave along the canal) or completely emptying an intermediate chamber (although this shows that

The Great Plague of Milan in 1629–31, that claimed the lives of an estimated 60,000 people out of a population of 130,000, caused unprecedented devastation in the city and was effectively described by Alessandro Manzoni in his masterpiece The Betrothed . This episode was seen by many as

10804-616: The Swiss at the Battle of Marignan , the duchy was promised to the French king François I . When the Spanish Habsburg Emperor Charles V defeated François I at the Battle of Pavia in 1525, northern Italy , which included Milan, passed to Habsburg Spain . In 1556, Charles V abdicated in favour of his son Philip II and his brother Ferdinand I . Charles's Italian possessions, including Milan, passed to Philip II and remained with

10950-470: The advent of canals in Britain. The sides of the turf-lock are sloping so, when full, the lock is quite wide. Consequently, this type of lock needs more water to operate than vertical-sided brick- or stone-walled locks. On British canals and waterways most turf-sided locks have been subsequently rebuilt in brick or stone, and so only a few good examples survive, such as at Garston Lock , and Monkey Marsh Lock , on

11096-480: The best examples of Neoclassical architecture in Lombardy. The Napoleonic rule of the city in 1805–1814, having established Milan as the capital of a satellite Kingdom of Italy , took steps to reshape it accordingly to its new status, with the construction of large boulevards, new squares ( Porta Ticinese by Luigi Cagnola and Foro Bonaparte by Giovanni Antonio Antolini ) and cultural institutions ( Art Gallery and

11242-463: The bottom cill at all but the higher tides – the new bottom chamber rises just far enough to get the boat over the original lock cill. In China, the recently completed Three Gorges Dam includes a double five-step staircase for large ships, and a ship lift for vessels of less than 3000 metric tons. Examples of "apparent" staircases are Foxton Locks and Watford Locks on the Leicester Branch of

11388-617: The canal would cause frequent interruptions of the heavy road traffic. It can be emptied by pumping – but as this uses a lot of electricity the method used when water supplies are adequate is to drain the lock to a nearby burn . In 2016 the Kieldrecht Lock in the Port of Antwerp in Belgium took over the title of the world's largest lock from the Berendrecht Lock in the same port and still has

11534-471: The capital city, has been the mayor of the Metropolitan City. Milan is also the capital of Lombardy , one of the twenty regions of Italy. Lombardy is by far the most populated region of Italy, with more than ten million inhabitants, almost one sixth of the national total. It is governed by a Regional Council, composed of 80 members elected for a five-year term. On 26 March 2018, a list of candidates of

11680-588: The chambers so that some water from the emptying chamber helps to fill the other. This facility has long been withdrawn on the English canals, although the disused paddle gear can sometimes be seen, as at Hillmorton on the Oxford Canal . Elsewhere they are still in use; a pair of twinned locks was opened in 2014 on the Dortmund–Ems Canal near Münster , Germany. The once-famous staircase at Lockport, New York ,

11826-617: The chambers still have common gates, but the water does not pass directly from one chamber to the next, going instead via side ponds. This means it is not necessary to ensure that the flight is full or empty before starting. Examples of famous "real" staircases in England are Bingley and Grindley Brook . Two-rise staircases are more common: Snakeholme Lock and Struncheon Hill Lock on the Driffield Navigation were converted to staircase locks after low water levels hindered navigation over

11972-404: The chance of a boat finding a lock set in its favour. There can also be water savings: the locks may be of different sizes, so that a small boat does not need to empty a large lock; or each lock may be able to act as a side pond (water-saving basin) for the other. In this latter case, the word used is usually "twinned": here indicating the possibility of saving water by synchronising the operation of

12118-502: The city as a global capital of innovation has been instrumental in its successful bids for hosting large international events such as 2015 Expo and 2026 Winter Olympics . Milan is located in the north-western section of the Po Valley , approximately halfway between the river Po to the south and the foothills of the Alps with the great lakes ( Lake Como , Lake Maggiore and Lake Lugano ) to

12264-505: The city centre reflects the Navigli , an ancient system of navigable and interconnected canals, now mostly covered. The suburbs of the city have expanded mainly to the north, swallowing up many comuni along the roads towards Varese, Como, Lecco and Bergamo. In the 21st century the Navigli region of Milan is a highly active area with a large number of residential units, bars and restaurants. It

12410-565: The city under the name Medhelanon. According to the legend reported by Livy (writing between 27 and 9 BC), the Gaulish king Ambicatus sent his nephew Bellovesus into northern Italy at the head of a party drawn from various Gaulish tribes; Bellovesus allegedly founded the settlement in the times of the Roman monarchy, during the reign of Tarquinius Priscus . Tarquin is traditionally recorded as reigning from 616 to 579 BC, according to ancient Roman historian Titus Livy. Medhelanon, in particular,

12556-447: The city. A new, more eclectic form of architecture can be seen in buildings such as Castello Cova, built the 1910s in a distinctly neo-medieval style, evoking the architectural trends of the past. An important example of Art Deco , which blended such styles with Fascist architecture , is the huge Central railway station inaugurated in 1931. The post-World War II period saw rapid reconstruction and fast economic growth, accompanied by

12702-562: The commune form of local government first established in the 11th century. In 1395, Gian Galeazzo Visconti became the first Duke of Milan upon receiving the title from Wenceslaus, King of the Romans . In 1447 Filippo Maria Visconti , Duke of Milan, died without a male heir; following the end of the Visconti line, the Ambrosian Republic was established; it took its name from St. Ambrose,

12848-514: The concept has been suggested in a number of cases, the only example in the world of a drop lock that has actually been constructed is at Dalmuir on the Forth and Clyde Canal in Scotland. This lock, of the single-chamber type, was incorporated during the restoration of the canal, to allow the replacement of a swing bridge (on a busy A road) by a fixed bridge, and so answer criticisms that the restoration of

12994-415: The creation of the Celtic sanctuary, the first residential settlements began to be built around it. Medhelanon then transformed from a simple religious center to an urban and then military centre, thus becoming a real village. The first homes were built just south of the Celtic sanctuary, near the modern Royal Palace of Milan . Subsequently, with the growth of the town centre, other important buildings for

13140-443: The development of art history, and has been the cradle of a number of modern art movements. There are only few remains of the ancient Roman city, notably the well-preserved Colonne di San Lorenzo . During the second half of the 4th century, Saint Ambrose , as bishop of Milan, had a strong influence on the layout of the city, reshaping the centre (although the cathedral and baptistery built in Roman times are now lost) and building

13286-531: The development of mulberry cultivation and silk processing. Following this economic growth, works such as the Sforza Castle (already existing in the Visconti era under the name of Porta Giovia Castle, but re-adapted, enlarged and completed by the Sforza family) and the Ospedale Maggiore were completed. The Sforzas also managed to attract to Milan personalities such as Leonardo da Vinci , who redesigned and improved

13432-448: The first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. All pound locks have three elements: The principle of operating a lock is simple. For instance, if a boat travelling downstream finds the lock already full of water: If the lock were empty, the boat would have had to wait 5 to 10 minutes while the lock was filled. For

13578-599: The first true pound lock was built in 1396 at Damme near Bruges , Belgium. The Italian Bertola da Novate (c. 1410–1475) constructed 18 pound locks on the Naviglio di Bereguardo (part of the Milan canal system sponsored by Francesco Sforza ) between 1452 and 1458. In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs : Ptolemy II is credited by some for being

13724-425: The flight quickly; and where water is in short supply, a single pump can recycle water to the top of the whole flight. The need for a flight may be determined purely by the lie of the land, but it is possible to group locks purposely into flights by using cuttings or embankments to "postpone" the height change. Examples: Caen Hill locks, Devizes . "Flight" is not synonymous with "Staircase" (see below). A set of locks

13870-512: The form of the now-disused Écluse des Lorraines , connecting the Canal latéral à la Loire with the River Allier . A drop lock can consist of two conventional lock chambers leading to a sump pound, or a single long chamber incorporating the sump – although the term properly applies only to the second case. As the pounds at either end of the structure are at the same height, the lock can only be emptied either by allowing water to run to waste from

14016-500: The function of the navigli and painted The Last Supper , and Bramante , who worked on the church of Santa Maria presso San Satiro , on the basilica of Sant'Ambrogio and to the church of Santa Maria delle Grazie , influencing the development of the Lombard Renaissance . Milan's last independent ruler, Lodovico il Moro , requested the aid of Charles VIII of France against the other Italian states , eventually unleashing

14162-574: The great basilicas at the city gates: Sant'Ambrogio , San Nazaro in Brolo , San Simpliciano and Sant'Eustorgio , which still stand, refurbished over the centuries, as some of the finest and most important churches in Milan. Milan's Cathedral , built between 1386 and 1877, is the largest church in the Italian Republic—the larger St. Peter's Basilica is in the State of Vatican City , a sovereign state—and

14308-552: The headquarters of national and international banks and companies. In terms of GDP, Milan is the wealthiest city in Italy, having also one of the largest economies among EU cities. Milan is viewed along with Turin as the southernmost part of the Blue Banana urban development corridor (also known as the "European Megalopolis"), and one of the Four Motors for Europe . Milan is a major international tourist destination, appearing among

14454-516: The inside walls of the lock with wood, so as not to abrade the boats. This was done, for instance, on the Chesapeake and Ohio Canal with the locks near the Paw Paw Tunnel . and also the Chenango Canal On large modern canals, especially very large ones such as ship canals , the gates and paddles are too large to be hand operated, and are operated by hydraulic or electrical equipment. On

14600-536: The insurgents and organised a plebiscite that ratified by a huge majority the unification of Lombardy with Piedmont–Sardinia. But just a few months later the Austrians were able to send fresh forces that routed the Piedmontese army at the Battle of Custoza on 24 July and to reassert Austrian control over northern Italy. About ten years later, however, Italian nationalist politicians, officers and intellectuals such as Cavour , Garibaldi and Mazzini were able to gather

14746-414: The intermediate pounds have disappeared, and the upper gate of one lock is also the lower gate of the one above it. However, it is incorrect to use the terms staircase and flight interchangeably: because of the absence of intermediate pounds, operating a staircase is very different from operating a flight. It can be more useful to think of a staircase as a single lock with intermediate levels (the top gate

14892-450: The lock caused the upstream gates to slam shut, breaking them also, and sending a cascade of water over the boat, sinking it. This suspended navigation on the canal for 48 hours until the lock gates could be replaced and the boat removed from the lock. To economise, especially where good stone would be prohibitively expensive or difficult to obtain, composite locks were made, i.e. they were constructed using rubble or inferior stone, dressing

15038-413: The lock on their level and therefore set the lock in their favour – saving about 5 to 10 minutes. However, this is not true for staircase locks, where it is quicker for boats to go through in convoy, and it also uses less water. The rise is the change in water-level in the lock. The two deepest locks on the English canal system are Bath deep lock on the Kennet and Avon Canal and Tuel Lane Lock on

15184-462: The major South European rail hub for goods and passenger transport. Indeed, Milan and Venice were among the main stops of the Orient Express that started operating from 1919. Abundant hydroelectric resources allowed the development of a strong steel and textile sector and, as Milanese banks dominated Italy's financial sphere, the city became the country's leading financial centre. In May 1898, Milan

15330-416: The mass media to nickname the metropolis "Milano da bere" , literally "Milan to be drunk". But in the 1990s Milan was badly affected by Tangentopoli , a political scandal in which many politicians and businessmen were tried for corruption. The city was also affected by a severe financial crisis and a steady decline in textiles, automobile and steel production. Berlusconi's Milano 2 and Milano 3 projects were

15476-563: The modern Pavia ), and left early-medieval Milan to the governance of its archbishops . After the siege of the city by the Visigoths in 402, the imperial residence moved to Ravenna . Attila , King of the Huns , sacked and devastated the city in 452 AD. In 539 the Ostrogoths conquered and destroyed Milan during the Gothic War against Byzantine Emperor Justinian I . In the summer of 569

15622-411: The most important housing projects of the 1980s and 1990s in Milan and brought to the city new economical and social energy. In the early 21st century Milan underwent a series of sweeping redevelopments over huge former industrial areas. Two new business districts, Porta Nuova and CityLife , were built in the space of a decade, radically changing the skyline of the city. Its exhibition centre moved to

15768-459: The most visited cities in the world, ranking second in Italy after Rome, fifth in Europe and sixteenth in the world. Milan is a major cultural centre, with museums and art galleries that include some of the most important collections in the world, such as major works by Leonardo da Vinci . It also hosts numerous educational institutions, academies and universities, with 11% of the national total of enrolled students. Founded around 590 BC under

15914-483: The name Medhelanon by a Celtic tribe belonging to the Insubres group and belonging to the Golasecca culture , it was conquered by the ancient Romans in 222 BC, who Latinized the name of the city into Mediolanum . The city's role as a major political centre dates back to the late antiquity , when it served as the capital of the Western Roman Empire . From the 12th century until the 16th century, Milan

16060-459: The name element -lanon is the Celtic equivalent of Latin -planum "plain", thus *Mediolanon (Latinized as Mediolānum ) meant "(settlement) in the midst of the plain". Mediolanum became the most important center of Cisalpine Gaul and, in the wake of economic development, in 49 BC, was elevated, within the Lex Roscia , to the status of municipium . The ancient Celtic settlement was, from

16206-509: The name to the scrofa semilanuta ("half-woolly sow") an ancient emblem of the city, fancifully accounted for in Andrea Alciato 's Emblemata (1584), beneath a woodcut of the first raising of the city walls, where a boar is seen lifted from the excavation, and the etymology of Mediolanum given as "half-wool", explained in Latin and in French. According to this theory, the foundation of Milan

16352-656: The new canal was low. This resulted in a sequential pair of locks, with gates pointing in opposite directions: one example was at Hall Green near Kidsgrove , where the southern terminus of the Macclesfield Canal joined the Hall Green Branch of the earlier Trent and Mersey Canal . The four gate stop lock near Kings Norton Junction, between the Stratford-upon-Avon Canal and the Worcester and Birmingham Canal

16498-441: The new political power of the cities and their will to fight against all feudal powers. Milan was no exception. It did not take long, however, for the Italian city-states to begin fighting each other to try to limit neighbouring powers. The Milanese destroyed Lodi and continuously warred with Pavia, Cremona and Como, who in turn asked Frederick I Barbarossa for help. In a sally they captured Empress Beatrice and forced her to ride

16644-594: The north, the Ticino river to the west and the Adda to the east. The city's land is flat, the highest point being at 122 m (400.26 ft) above sea level . The administrative comune covers an area of about 181 square kilometres (70 sq mi), with a population, in 2013, of 1,324,169 and a population density of 7,315 inhabitants per square kilometre (18,950/sq mi). The Metropolitan City of Milan covers 1,575 square kilometres (608 sq mi) and in 2015 had

16790-479: The other Italian statelets and proclaim the birth of the Kingdom of Italy on 17 March 1861. The political unification of Italy enhanced Milan's economic dominance over northern Italy. A dense rail network, whose construction had started under Austrian patronage, was completed in a brief time, making Milan the rail hub of northern Italy and, with the opening of the Gotthard (1882) and Simplon (1906) railway tunnels,

16936-475: The people of Milan, but they also gave a great impulse to culture, with the creation of the Biblioteca Ambrosiana , in a building designed by Francesco Maria Richini , and the nearby Pinacoteca Ambrosiana . Many notable churches and Baroque mansions were built in the city during this period by the architects, Pellegrino Tibaldi , Galeazzo Alessi and Richini himself. Empress Maria Theresa of Austria

17082-604: The plain", or of "place between watercourses" (Celtic medhe = "in the middle, central"; land or lan = "land"), given the presence of the Olona , Lambro , Seveso rivers and the Nirone and Pudiga streams. The Latin name Mediolanum comes from the Latin words medio (in the middle) and planus (plain). However, some scholars believe that lanum comes from the Celtic root lan , meaning an enclosure or demarcated territory (source of

17228-805: The popular patron saint of the city. Both the Guelph and the Ghibelline factions worked together to bring about the Ambrosian Republic in Milan. Nonetheless, the Republic collapsed when, in 1450, Milan was conquered by Francesco I of the House of Sforza , which made Milan one of the leading cities of the Italian Renaissance . Under the House of Sforza, Milan experienced a period of great prosperity, which in particular saw

17374-461: The required level was reached, and then when the time came it was allowed to flow out. The water level could differ by 4 or 5 feet (1.2 or 1.5 m) at each lock and in the Grand Canal the level was raised in this way by 138 feet (42 m). In medieval Europe a sort of pound lock was built in 1373 at Vreeswijk , Netherlands. This pound lock serviced many ships at once in a large basin . Yet

17520-497: The sea. During winter daily average temperatures can fall below freezing (0 °C [32 °F]) and accumulations of snow can occur: the historic average of Milan's area is 25 centimetres (10 in) in the period between 1961 and 1990, with a record of 90 centimetres (35 in) in January 1985. In the suburbs the average can reach 36 centimetres (14 in). The city receives on average seven days of snow per year. The city

17666-471: The seat of an elegant Renaissance court surrounded by a walled hunting park. Notable architects involved in the project included the Florentine Filarete , who was commissioned to build the high central entrance tower, and the military specialist Bartolomeo Gadio. The alliance between Francesco Sforza and Florence's Cosimo de' Medici bore to Milan Tuscan models of Renaissance architecture, apparent in

17812-437: The soil , causing Milan to be one of Europe's most polluted cities. Summers in Milan are hot and humidity levels are high with peak temperatures reaching above 35 °C (95 °F). Due to the high humidity, urban heat effect and lack of wind, nighttimes often remain muggy during the summer months. Usually the summer enjoys clearer skies with an average of more than 13 hours of daylight: when precipitation occurs though, it

17958-624: The solid part of the lock cill. On the Oxford Canal it is called a babbie; on the Grand Union Canal it is referred to as the cill bumper. Some canal operation authorities, primarily in the United States and Canada, call the ledge a miter sill (mitre sill in Canada). Gates are the watertight doors which seal off the chamber from the upper and lower pounds. Each end of the chamber is equipped with

18104-407: The spilled grain. In 984 Qiao installed a pair of sluice-gates two hundred and fifty feet apart, the entire structure roofed over like a building. By siting two staunch gates so close to one another, Qiao had created a short stretch of canal, effectively a pound-lock, filled from the canal above by raising individual wooden baulks in the top gate and emptied into the canal below by lowering baulks in

18250-585: The spire), and the 209 m Allianz Tower , a 50-story tower. The largest parks in the central area of Milan are Sempione Park , at the north-western edge, and Montanelli Gardens , situated north-east of the city. English-style Sempione Park, built in 1890, contains the Civic Arena , the Civic Aquarium of Milan (which is the third oldest aquarium in Europe ), a steel lattice panoramic tower, an art exhibition centre,

18396-411: The staircase by moving sideways around each other; or at peak times, one can have all the chambers full simultaneously with boats travelling in the same direction. When variable conditions meant that a higher water level in the new canal could not be guaranteed, then the older company would also build a stop lock (under its own control, with gates pointing towards its own canal) which could be closed when

18542-413: The sump to a lower stream or drain, or (less wastefully) by pumping water back up to the canal. Particularly in the two-chamber type, there would be a need for a bypass culvert, to allow water to move along the interrupted pound and so supply locks further down the canal. In the case of the single-chamber type, this can be achieved by keeping the lock full and leaving the gates open while not in use. While

18688-639: The symbol of Spanish bad rule and decadence and is considered one of the last outbreaks of the centuries-long pandemic of plague that began with the Black Death . In 1700, the Spanish line of Habsburgs was extinguished with the death of Charles II . After his death, the War of the Spanish Succession began in 1701. In 1706, the French were defeated in Ramillies and Turin and were forced to yield northern Italy to

18834-488: The title for largest volume. In 2022 the IJmuiden sea lock serving the Port of Amsterdam became the world's largest lock by surface area. The lock is 500 m (1,600 ft) long, 70 m (230 ft) wide and has sliding lock gates creating a usable depth of 18 m (59 ft). The size of locks cannot be compared without considering the difference in water level that they are designed to operate under. For example,

18980-400: The top gate and raising ones in the lower. A turf-sided lock is an early form of canal lock design that uses earth banks to form the lock chamber, subsequently attracting grasses and other vegetation, instead of the now more familiar and widespread brick, stone, or concrete lock wall constructions. This early lock design was most often used on river navigations in the early 18th century before

19126-404: The upstream lock to give them an extra heavy swell, which consisted of opening all the paddles on the lock gate, creating a surge that affected the whole pound below. On the Erie Canal, some loaded boats needed a swell to get out of the lock. Particularly lumber boats, being top heavy, would list to one side and get stuck in the lock, and needed a swell to get them out. Some lockkeepers would give

19272-529: The urban area of Milan is one of the 15 Metropolitan municipalities ( città metropolitane ), new administrative bodies fully operative since 1 January 2015. The new Metro municipalities, giving large urban areas the administrative powers of a province, are conceived for improving the performance of local administrations and to slash local spending by better co-ordinating the municipalities in providing basic services (including transport, school and social programs) and environment protection. In this policy framework,

19418-405: The windlass (or handle) out of one's hands, or if one was standing in the wrong place, could knock one into the canal, leading to injuries and drownings. On the Chesapeake and Ohio Canal, the lockkeepers were required to remove the windlasses from all lock paddles at night, to prevent unauthorized use. A swell was caused by opening suddenly the paddle valves in the lock gates, or when emptying

19564-449: Was aligned towards the heliacal rising of Antares , while the other towards the heliacal rising of Capella . The latter coincided with a Celtic spring festival celebrated on 24 March, while the heliacal rising of Antares corresponded with 11 November, which opened and closed the Celtic year and which coincided with the point where the Sun rose on the winter solstice . About two centuries after

19710-456: Was all that need be emptied when a boat passed through. This type of lock, called a pound lock was known in Imperial China and ancient Europe and was used by Greek engineers in the Canal of the Pharaohs under Ptolemy II (284 to 246 BC), when engineers solved the problem of overcoming the difference in height through canal locks . Pound locks were first used in medieval China during

19856-416: Was also a doubled set of locks. Five twinned locks allowed east- and west-bound boats to climb or descend the 60 feet (18 m) Niagara Escarpment , a considerable engineering feat in the nineteenth century. While Lockport today has two large steel locks, half of the old twin stair acts as an emergency spillway and can still be seen, with the original lock gates having been restored in early 2016. Loosely,

20002-453: Was based on these early paths, and on the shape of the sanctuary, reached, in some cases, up to the 19th century and even beyond. For example, the route of the modern Corso Vittorio Emanuele, Piazza del Duomo , Piazza Cordusio and Via Broletto, which is curvilinear, could correspond to the south side of the ellipse of the ancient sanctuary of Medhelanon. One axis of the Medhelanon sanctuary

20148-470: Was demolished using 400 linear shaped charges . In 1999 a new bridge was constructed just down stream of the 1880 crossing. The new bridge is the first in Ohio to use the cast-in-place reinforced concrete box with the balanced cantilever method of construction. The new bridge, while of a new design, incorporates architectural details of the older bridge. The new bridge cost US$ 11.4 million. The bridge connects

20294-510: Was developed around a sanctuary , which was the oldest area of the village. The sanctuary, which consisted of a wooded area in the shape of an ellipse with a central clearing, was aligned according to precise astronomical points. For this reason, it was used for religious gatherings, especially in particular celebratory moments. The sanctuary of Medhelanon was an ellipse with axes of 443 m (1,453 ft) and 323 m (1,060 ft) located near Piazza della Scala . The urban planning profile

20440-565: Was often shrouded in thick cloud or fog during winter, although the removal of rice paddies from the southern neighbourhoods and the urban heat island effect have greatly reduced this occurrence since the turn of the 21st century. Occasionally, the Foehn winds cause the temperatures to rise unexpectedly: on 22 January 2012 the daily high reached 16 °C (61 °F) while on 22 February 2012 it reached 21 °C (70 °F). Air pollution levels rise significantly in wintertime when cold air clings to

20586-651: Was one of the largest European cities and a major trade and commercial centre, as the capital of the Duchy of Milan , one of the greatest political, artistic and fashion forces in the Renaissance . Having become one of the main centres of the Italian Enlightenment during the early modern period , it then became one of the most active centres during the Restoration , until its entry into the unified Kingdom of Italy . From

20732-615: Was rapidly rebuilt, with the construction of several innovative and modernist skyscrapers, such as the Torre Velasca and the Pirelli Tower , that soon became the symbols of this new era of prosperity. The economic prosperity was, however, overshadowed in the late 1960s and early 1970s during the so-called Years of lead , when Milan witnessed an unprecedented wave of street violence, labour strikes and political terrorism . The apex of this period of turmoil occurred on 12 December 1969, when

20878-539: Was replaced in 1914 by a pair of guillotine lock gates which stopped the water flow regardless of which canal was higher. These gates have been permanently open since nationalisation. The best known example of a round lock is the Agde Round Lock on the Canal du Midi in France. This serves as a lock on the main line of the canal and allows access to the Hérault River . A second French round lock can be found in

21024-427: Was responsible for the significant renovations carried out in Milan during the 18th century. This urban and artistic renewal included the establishment of Teatro alla Scala , inaugurated in 1778, and the renovation of the Royal Palace . The late 1700s Palazzo Belgioioso by Giuseppe Piermarini and Royal Villa of Milan by Leopoldo Pollack , later the official residence of Austrian viceroys, are often regarded among

21170-477: Was shaken by the Bava Beccaris massacre , a riot related to soaring cost of living. Milan's northern location in Italy closer to Europe, secured also a leading role for the city on the political scene. It was in Milan that Benito Mussolini built his political and journalistic careers, and his fascist Blackshirts rallied for the first time in the city's Piazza San Sepolcro ; here the future Fascist dictator launched his March on Rome on 28 October 1922. During
