The Sands of Beirut were a series of archaeological sites located on the coastline south of Beirut in Lebanon .
106-450: The Sands were a complex of nearly 20 prehistoric sites that were destroyed due to building operations using the soft sandstone in constructing the city of Beirut and Beirut Airport . The large number of open air sites provided a wealth of flint relics from various periods including Natufian remains, unstratified but suggested to date between c. 10000 BC to c 8000 BC. Finds included sickles used for harvesting wild cereals as just prior to
212-404: A golf course, leaving only one standing. The circles were composed of large river boulders, varying in diameters between 8 metres (26 ft) and 15 metres (49 ft). A nearby ramleh outcrop contains a large, square empty cistern or well cut into the sandstone. Flints including Levallois cores, flakes and waste were dispersed across the whole area but gave little evidence regarding the age of
318-470: A thin section using a method like the Gazzi-Dickinson Method . This yields the relative percentages of quartz, feldspar, and lithic grains and the amount of clay matrix. The composition of a sandstone can provide important information on the genesis of the sediments when used with a triangular Q uartz, F eldspar, L ithic fragment ( QFL diagrams ). However, geologist have not been able to agree on
424-475: A cool atmosphere, an advantage in the hot Arab countries. Quotations from the Quran often adorn mosque interiors. These texts are meant to inspire people by their beauty, while also reminding them of the words of Allah. The prayer hall, also known as the muṣallá ( Arabic : مُصَلَّى ), rarely has furniture; chairs and pews are generally absent from the prayer hall so as to allow as many worshipers as possible to line
530-418: A covered building, but can be any place where Islamic prayers are performed, such as an outdoor courtyard. Originally, mosques were simple places of prayer for the early Muslims , and may have been open spaces rather than elaborate buildings. In the first stage of Islamic architecture (650–750 CE), early mosques comprised open and closed covered spaces enclosed by walls, often with minarets , from which
636-1000: A defining feature of South Asian mosque architecture during the Delhi Sultanate and reached their peak under the Mughal Empire. Influenced by Persian and Central Asian traditions, the Mughals introduced the iconic onion-shaped domes, seen in landmarks like the Jama Masjid in Delhi and the Badshahi Mosque in Lahore. These domes were not only visually striking but also represented remarkable engineering, using techniques such as iron dowels for strength and timber centering for precision. The Mughal architectural style still influences mosque design today. Modern Innovations One prime example of modern innovation
742-419: A half meters below the sands. A trace of Neolithic was found along with three Emireh points and a series of styled picks that were given their name from this site, known as Bir Hassan picks . Also called Tell aux Crochets , Tell Mouterde or Cote 52 , it is now built over by a refugee village. Finds from this site were recovered by Jesuits and included flint arrowheads and geometric Mesolithic tools. It

It introduced some of the features still common in today's mosques, including the niche at the front of the prayer space known as the mihrab (first added in the Umayyad period ) and the tiered pulpit called the minbar . The Umayyad Caliphate was particularly instrumental in spreading Islam and establishing mosques within the Levant , as

Dott's (1964) sandstone classification scheme is one of many such schemes used by geologists for classifying sandstones. Dott's scheme is a modification of Gilbert's classification of silicate sandstones, and it incorporates R.L. Folk's dual textural and compositional maturity concepts into one classification system. The philosophy behind combining Gilbert's and R. L. Folk's schemes
1378-459: A set of boundaries separating regions of the QFL triangle. Visual aids are diagrams that allow geologists to interpret different characteristics of a sandstone. For example, a QFL chart can be marked with a provenance model that shows the likely tectonic origin of sandstones with various compositions of framework grains. Likewise, the stage of textural maturity chart illustrates the different stages that

Also recovered were crested blades, two distinct types of arrowhead , awls, scrapers, polished axes , scissors , chisels, borers, scrapers, retouched blades, microburins and a few flaked picks. Jacques Cauvin has termed the collection of flints from this site as a "nucléus naviformes", which he claimed may represent an older type of lithic technology than found in

Although domes normally took on the shape of a hemisphere, the Mughals in India popularized onion-shaped domes in South Asia which has gone on to become characteristic of the Arabic architectural style of dome. Some mosques have multiple, often smaller, domes in addition to the main large dome that resides at
1802-576: A transverse arrowhead found by Auguste Bergy about 750 metres (2,460 ft) east of the minaret . This site is north of Shell petrol station, 8 kilometres (5.0 mi) south of Beirut near the Airport terminal. Some flints similar to the Neolithique Moyen period of Byblos were found at this site alongside Palaeolithic material. A semi-circular site northeast of the Shell petrol station continuing to
1908-445: A twofold classification: Cement is what binds the siliciclastic framework grains together. Cement is a secondary mineral that forms after deposition and during burial of the sandstone. These cementing materials may be either silicate minerals or non-silicate minerals, such as calcite. Sandstone that becomes depleted of its cement binder through weathering gradually becomes friable and unstable. This process can be somewhat reversed by
2014-837: Is a distinction that can be recognized in the field . In turn, the distinction between an orthoquartzite and a metaquartzite is the onset of recrystallization of existing grains. The dividing line may be placed at the point where strained quartz grains begin to be replaced by new, unstrained, small quartz grains, producing a mortar texture that can be identified in thin sections under a polarizing microscope. With increasing grade of metamorphism, further recrystallization produces foam texture , characterized by polygonal grains meeting at triple junctions, and then porphyroblastic texture , characterized by coarse, irregular grains, including some larger grains ( porphyroblasts .) Sandstone has been used since prehistoric times for construction, decorative art works and tools. It has been widely employed around
2120-651: Is a semicircular niche in the wall of a mosque that faces the qiblah (i.e. the "front" of the mosque); the imam stands in this niche and leads prayer. Given that the imam typically stands alone in the frontmost row, this niche's practical effect is to save unused space. The minbar is a pulpit from which the Friday sermon is delivered. While the minbar of Muhammad was a simple chair, later it became larger and attracted artistic attention. Some remained made of wood, albeit exquisitely carved, while others were made of marble and featured friezes . A common feature in mosques
2226-715: Is accorded to, in descending order of importance: al-Masjid al-Haram in the city of Mecca, where Hajj and Umrah are performed; the Prophet's Mosque in the city of Medina , where Muhammad is buried; and al-Aqsa Mosque in the city of Jerusalem , where Muslims believe that Muhammad ascended to heaven to meet God around 621 CE. There's a growing realization among scholars that the present-day perception of mosques doesn't fully align with their original concept. Early Islamic texts and practices highlight mosques as vibrant centers integral to Muslim communities, supporting religious, social, economic, and political affairs. During and after

It is located above the main prayer hall, elevated in the background as stairs-separated gallery or plateau (surface-shortened to the back relative to the bottom main part). It usually has a perforated fence at the front, through which the imam or mullah and the other male worshippers in the main hall can be partially seen. A miḥrāb , also spelled as mehrab
2438-546: Is composed of quartz or feldspar , because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand , sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topographic features, certain colors of sandstone have become strongly identified with certain regions, such as
2544-724: Is credited with having built the Ka'bah in Mecca, and consequently its sanctuary, Al-Masjid al-Haram , which is seen by Muslims as the first mosque that existed. A hadith in Sahih al-Bukhari states that the sanctuary of the Ka'bah was the first mosque on Earth, with the second mosque being Al-Aqsa in Jerusalem , which is also associated with Abraham. Since as early as 638 CE, the Sacred Mosque of Mecca has been expanded on several occasions to accommodate
2650-523: Is likely formed during eogenesis. Deeper burial is accompanied by mesogenesis , during which most of the compaction and lithification takes place. Compaction takes place as the sand comes under increasing pressure from overlying sediments. Sediment grains move into more compact arrangements, ductile grains (such as mica grains) are deformed, and pore space is reduced. In addition to this physical compaction, chemical compaction may take place via pressure solution . Points of contact between grains are under
2756-417: Is often elaborated into a freestanding building in the center of a courtyard. This desire for cleanliness extends to the prayer halls where shoes are disallowed to be worn anywhere other than the cloakroom. Thus, foyers with shelves to put shoes and racks to hold coats are commonplace among mosques. Modern mosques have a variety of amenities available to their congregants. As mosques are supposed to appeal to

Chemical compaction continues to depths of 2,000 meters (6,600 ft), and most cementation takes place at depths of 2,000–5,000 meters (6,600–16,400 ft). Unroofing of buried sandstone is accompanied by telogenesis , the third and final stage of diagenesis. As erosion reduces

Dott's classification scheme is based on the mineralogy of framework grains, and on the type of matrix present in between the framework grains. In this specific classification scheme, Dott has set the boundary between arenite and wackes at 15% matrix. In addition, Dott also breaks up

Outside of the Iberian Peninsula , such instances also occurred in southeastern Europe once regions were no longer under Muslim rule. There are two holidays ( Eids ) in the Islamic calendar : ʿĪd al-Fiṭr and ʿĪd al-Aḍḥā , during which there are special prayers held at mosques in
3180-576: Is the Masjid Raja Haji Fi Sabilillah in Malaysia, which features a Low-E glass dome. The use of Low-E (low emissivity) glass allows for significant energy efficiency by reducing heat gain while still allowing natural light to illuminate the interior space. This technique helps to maintain a comfortable temperature inside the mosque, minimizing reliance on air conditioning, and promoting sustainability . In addition to advancements in materials,
3286-411: Is the minaret, the tall, slender tower that usually is situated at one of the corners of the mosque structure. The top of the minaret is always the highest point in mosques that have one, and often the highest point in the immediate area. The origin of the minaret and its initial functions are not clearly known and have long been a topic of scholarly discussion. The earliest mosques lacked minarets, and

Early Javanese mosques took design cues from Hindu , Buddhist , and Chinese architectural influences, with tall timber, multi-level roofs similar to the pagodas of Balinese Hindu temples ; the ubiquitous Islamic dome did not appear in Indonesia until the 19th century. In turn, the Javanese style influenced the styles of mosques in Indonesia's Austronesian neighbors— Malaysia , Brunei , and

It is typical of mosque buildings to have a special ornamental niche (a mihrab ) set into the wall in the direction of the city of Mecca (the qibla ), which Muslims must face during prayer, as well as a facility for ritual cleansing ( wudu ). The pulpit ( minbar ), from which public sermons ( khutbah ) are delivered on the event of Friday prayer , was, in earlier times, characteristic of

The Iqâmah (Arabic: إِقَـامَـة ), which is similar to the adhan and proclaimed right before the commencement of prayers, is usually not proclaimed from the minaret even if a mosque has one. Domes, often placed directly above the main prayer hall, may signify the vaults of the heaven and sky. As time progressed, domes grew, from occupying

Several of the early mosques in the Ottoman Empire were originally churches or cathedrals from the Byzantine Empire , with the Hagia Sophia (one of those converted cathedrals) informing the architecture of mosques from after the Ottoman conquest of Constantinople . The Ottomans developed their own architectural style characterized by large central domes (sometimes surrounded by multiple smaller domes), pencil-shaped minarets, and open façades. Mosques from

Pore space includes the open spaces within a rock or a soil. The pore space in a rock has a direct relationship to the porosity and permeability of the rock. The porosity and permeability are directly influenced by the way the sand grains are packed together. Sandstones are typically classified by point-counting
5830-406: The call to prayer was often performed from smaller structures or elevated platforms. The early Muslim community of Medina gave the call to prayer from the doorway or the roof of the house of Muhammad , which doubled as a place for prayer. The first confirmed minarets in the form of towers date from the early 9th century under Abbasid rule and they did not become a standard feature of mosques until
5936-717: The center. Structural and Functional Roles Domes not only serve as architectural focal points but also enhance mosque acoustics, amplifying prayers. Structurally, they allow vast interior spaces with minimal internal supports. Their placement above the prayer hall symbolizes the connection between the earthly and the divine, reinforcing the mosque's spiritual purpose. Persian and Byzantine Influence Whilst squinches and pendentives were not first used in mosques, they were later incorporated in dome design and were essential in transitioning from square rooms to circular domes. Squinches, which originated in Persian and Roman architecture, fill
6042-879: The central city mosque, but has since become common in smaller mosques. To varying degrees, mosque buildings are designed so that there are segregated spaces for men and women . This basic pattern of organization has assumed different forms depending on the region, period, and Islamic denomination . In addition to being places of worship in Islam , mosques also serve as locations for funeral services and funeral prayers , marriages ( nikah ), vigils during Ramadan , business agreements, collection and distribution of alms , and homeless shelters. To this end, mosques have historically been multi-purpose buildings functioning as community centres, courts of law, and religious schools . In modern times, they have also preserved their role as places of religious instruction and debate. Special importance

Because of the community contribution necessary to serve iftar dinners, mosques with smaller congregations may not be able to host the iftar dinners daily. Some mosques will also hold Suḥūr meals before dawn to congregants attending the first required prayer of the day, Fajr . As with iftar dinners, congregants usually provide the food for suhoor, although able mosques may provide food instead. Mosques will often invite poorer members of

Pressure solution contributes to cementing, as the mineral dissolved from strained contact points
7950-442: The hardness of individual grains, uniformity of grain size and friability of their structure, some types of sandstone are excellent materials from which to make grindstones , for sharpening blades and other implements. Non-friable sandstone can be used to make grindstones for grinding grain, e.g., gritstone . A type of pure quartz sandstone, orthoquartzite, with more of 90–95 percent of quartz, has been proposed for nomination to
8056-525: The holiday of Eid ul-Fitr , mosques also collect a special zakat that is supposed to assist in helping poor Muslims attend the prayers and celebrations associated with the holiday. The frequency by which Muslims attend mosque services vary greatly around the world. In some countries, weekly attendance at religious services is common among Muslims while in others, attendance is rare. A study of American Muslims did not find differences in mosque attendance by gender or age. Arab-plan or hypostyle mosques are
8162-506: The increasing number of Muslims who either live in the area or make the annual pilgrimage known as Hajj to the city. Either way, after the Quba Mosque, Muhammad went on to establish another mosque in Medina , which is now known as Al-Masjid an-Nabawi ('The Prophet's Mosque'). Built on the site of his home, Muhammad participated in the construction of the mosque himself and helped pioneer
8268-489: The majority, mosques are prohibited from loudly broadcasting the Adhān (Arabic: أَذَان , Call to Prayer), although it is supposed to be said loudly to the surrounding community. The adhan is required before every prayer. Nearly every mosque assigns a muezzin for each prayer to say the adhan as it is a recommended practice or Sunnah ( Arabic : سُـنَّـة ) of the Islamic prophet Muhammad. At mosques that do not have minarets,
8374-412: The majority, will also host Eid prayers outside in courtyards, town squares or on the outskirts of town in an Eidgah . Islam's holiest month, Ramaḍān , is observed through many events. As Muslims must fast during the day during Ramadan, mosques will host Ifṭār dinners after sunset and the fourth required prayer of the day, that is Maghrib . Food is provided, at least in part, by members of
8480-425: The morning. These Eid prayers are supposed to be offered in large groups, and so, in the absence of an outdoor Eidgah , a large mosque will normally host them for their congregants as well as the congregants of smaller local mosques. Some mosques will even rent convention centers or other large public buildings to hold the large number of Muslims who attend. Mosques, especially those in countries where Muslims are
8586-526: The most archaic neolithic levels from Byblos . The site has shown many similarities to Damascus basin sites and compared to the very earliest levels of Tell Ramad , dating to the earliest stage of the PPNB . Sandstone Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains, cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks . Most sandstone
8692-493: The much lower temperatures and pressures associated with diagenesis of sedimentary rock, but diagenesis has cemented the rock so thoroughly that microscopic examination is necessary to distinguish it from metamorphic quartzite. The term orthoquartzite is used to distinguish such sedimentary rock from metaquartzite produced by metamorphism. By extension, the term orthoquartzite has occasionally been more generally applied to any quartz-cemented quartz arenite . Orthoquartzite (in
8798-464: The narrow sense) is often 99% SiO 2 with only very minor amounts of iron oxide and trace resistant minerals such as zircon , rutile and magnetite . Although few fossils are normally present, the original texture and sedimentary structures are preserved. The typical distinction between a true orthoquartzite and an ordinary quartz sandstone is that an orthoquartzite is so highly cemented that it will fracture across grains, not around them. This
8904-514: The opportunities for further development, the mosques consequently losing popularity. The first departure within mosque design started in Persia (Iran). The Persians had inherited a rich architectural legacy from the earlier Persian dynasties, and they began incorporating elements from earlier Parthian and Sassanid designs into their mosques, influenced by buildings such as the Palace of Ardashir and
9010-638: The product of physical and chemical weathering of bedrock. Weathering and erosion are most rapid in areas of high relief, such as volcanic arcs , areas of continental rifting , and orogenic belts . Eroded sand is transported by rivers or by the wind from its source areas to depositional environments where tectonics has created accommodation space for sediments to accumulate. Forearc basins tend to accumulate sand rich in lithic grains and plagioclase . Intracontinental basins and grabens along continental margins are also common environments for deposition of sand. As sediments continue to accumulate in
9116-704: The red rock deserts of Arches National Park and other areas of the American Southwest . Rock formations composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs . Quartz-bearing sandstone can be changed into quartzite through metamorphism , usually related to tectonic compression within orogenic belts . Sandstones are clastic in origin (as opposed to either organic , like chalk and coal , or chemical , like gypsum and jasper ). The silicate sand grains from which they form are
9222-490: The rest of the Muslim community is responsible for providing the participants with food, drinks, and whatever else they need during their stay. The third of the Five Pillars of Islam states that Muslims are required to give approximately one-fortieth of their wealth to charity as Zakat . Since mosques form the center of Muslim communities, they are where Muslims go to both give zakat and, if necessary, collect it. Before
9328-496: The rest of the prayer area, and to the rest of the mosque complex (although such uses may be restricted by the conditions of the waqf that owns the mosque). In many mosques, especially the early congregational mosques, the prayer hall is built in the hypostyle form (the roof held up by a multitude of columns). One of the finest examples of the hypostyle-plan mosques is the Great Mosque of Kairouan in Tunisia . Usually opposite
9434-634: The rise of privately funded mosques, many of which serve as bases for different streams of Islamic revivalism and social activism. The word 'mosque' entered the English language from the French word mosquée , probably derived from Italian moschea (a variant of Italian moscheta ), from either Middle Armenian մզկիթ ( mzkit‘ ), Medieval Greek : μασγίδιον ( masgídion ), or Spanish mezquita , from [مسجد] Error: {{Lang}}: invalid parameter: |3= ( help ) (meaning "site of prostration (in prayer)" and hence
9540-526: The room. Some mosques have Islamic calligraphy and Quranic verses on the walls to create a more religious atmosphere for worshippers. Often, a limited part of the prayer hall is sanctified formally as a masjid in the sharīʿah sense (although the term masjid is also used for the larger mosque complex as well). Once designated, there are onerous limitations on the use of this formally designated masjid , and it may not be used for any purpose other than worship; restrictions that do not necessarily apply to
9646-417: The sandstone are erased by the metamorphism. The grains are so tightly interlocked that when the rock is broken, it fractures through the grains to form an irregular or conchoidal fracture. Geologists had recognized by 1941 that some rocks show the macroscopic characteristics of quartzite, even though they have not undergone metamorphism at high pressure and temperature. These rocks have been subject only to
9752-662: The seventh century, they were not commonplace across the subcontinent until the arrival of the Mughals in the 16th and 17th centuries. Reflecting their Timurid origins, Mughal-style mosques included onion domes , pointed arches , and elaborate circular minarets, features common in the Persian and Central Asian styles . The Jama Masjid in Delhi and the Badshahi Mosque in Lahore , built in
9858-415: The site had been frequented by hunter-gatherer groups forming temporary camps and developed into a village during the early neolithic period. Tell aux Scies or Tell of Saws is located south of Beirut, in the dunes near the coast. Father Auguste Bergy collected PPNB materials from the site in 1932 before it was turned into landfill for rubbish. The large and notable assemblage from the site included
9964-408: The stone circles. Tell Arslan was a more substantial archaeological site in the Sands of Beirut than the open air surface stations, with a full tell mound covering 1 hectare (10,000 m) situated 8.5 kilometres (5.3 mi) south of Beirut and about 800 m east of the beach. It was first excavated by Father Auguste Bergy in 1930. It represents the earliest known neolithic village settlement in
10070-420: The towering gateways at every side, as more important than the actual buildings themselves. They typically took the form of a square-shaped central courtyard with large entrances at each side, giving the impression of gateways to the spiritual world. The Persians also introduced Persian gardens into mosque designs. Soon, a distinctly Persian style of mosques started appearing that would significantly influence
10176-747: The use of geodesic domes offers a modern solution to structural and environmental needs. These domes, with their network of triangular units, distribute weight evenly, allowing for expansive spaces without the need for internal supports. This is particularly useful in creating large, unobstructed prayer halls. Geodesic domes also boast greater energy efficiency due to their minimal surface area relative to volume, which reduces heating and cooling demands. As ritual purification precedes all prayers, mosques often have ablution fountains or other facilities for washing in their entryways or courtyards. Worshippers at much smaller mosques often have to use restrooms to perform their ablutions. In traditional mosques, this function
10282-549: The use of numerous columns and supports . One of the most notable hypostyle mosques is the Great Mosque of Cordoba in Spain, the building being supported by over 850 columns. Frequently, hypostyle mosques have outer arcades ( riwaq ) so that visitors can enjoy the shade. Arab-plan mosques were constructed mostly under the Umayyad and Abbasid dynasties. The simplicity of the Arab plan limited
10388-612: The world in constructing temples, churches, homes and other buildings, and in civil engineering . Although its resistance to weathering varies, sandstone is easy to work. That makes it a common building and paving material, including in asphalt concrete . However, some types that have been used in the past, such as the Collyhurst sandstone used in North West England , have had poor long-term weather resistance, necessitating repair and replacement in older buildings. Because of
10494-482: Was first discovered by Father René Mouterde and material was published by Godefroy Zumoffen in 1910, Auguste Bergy in 1932 and Henri Fleisch in 1956 and 1965. Microliths were found along with trapezoid and crescent arrowheads of the Natufian variety with tangs and notches along with Helwan points . Also found were a Ksar Akil flake , Emireh points and traces of a Neolithic settlement. A Ksar Akil flake (pictured)
10600-450: Was followed by extensive research by Father G. Zumoffen who published in 1893. Henri Fleisch also catalogued and recovered materials from the sites in the 1960s, the destruction of the Sands of Beirut was recently exhibited through Father Fleisch's photography in June 2010 at the Museum of Lebanese Prehistory . Sands of Beirut archaeological sites included: This site was located at the top of
10706-641: Was found here. There are two sites at Khan Khalde, 10 kilometres (6.2 mi) south of Beirut around the Khalde station. Site 1 or 3.A. is located west of the station buildings and contained mostly Middle Paleolithic material with traces of Mesolithic and Neolithic along with one Emireh point. Site 2 or 3.B. is a section in the railway cutting where material studies by Fathers Fleisch and Ramonnay determined to be largely Levalloiso - Mousterian with some Upper Paleolithic and Neolithic traces. They were found by Auguste Bergy, published by Henri Fleisch in 1965 and kept in
10812-619: Was founded by Albanian Americans in 1915, but the continent's oldest surviving mosque, the Mother Mosque of America , was built in 1934. As in Europe, the number of American mosques has rapidly increased in recent decades as Muslim immigrants, particularly from South Asia , have come in the United States. Greater than forty percent of mosques in the United States were constructed after 2000. According to early Muslim historians , towns that surrendered without resistance and made treaties with
10918-465: Was hardened by firing and included flat bases, a strap handle and a few sherds incised with stab marks and parallel lines. Jacques Cauvin concluded the artefacts similar and the site likely contemporary with middle neolithic periods of Byblos. A.M.T. Moore argued that finds such as Amuq points and short axes were more archaic still, possibly even dating into the Upper Paleolithic. He further suggested
11024-471: Was heavily influenced by Byzantine architecture with its use of large central domes. Islam forbids figurative art , on the grounds that the artist must not imitate God's creation. Mosques are, therefore, decorated with abstract patterns and beautiful inscriptions. Decoration is often concentrated around doorways and the miḥrāb . Tiles are used widely in mosques. They lend themselves to pattern-making, can be made with beautiful subtle colors, and can create
11130-467: Was mentioned by Fleisch in 1965, who considered it Levalloiso-Mousterian with a few pieces from the Neolithic. This site is on the right bank at the old mouth of the Nahr Ghedir. Material including an Emireh point, large quantities of Middle Paleolithic tools, a few Upper Paleolithic and a trace of Neolithic were discussed by Fleisch in 1965. This site is 5 kilometres (3.1 mi) south of Beirut also on
11236-516: Was the first mosque built in the Maghreb (northwest Africa), with its present form (dating from the ninth century) serving as a model for other Islamic places of worship in the Maghreb. It was the first in the region to incorporate a square minaret , which was characteristic of later Maghrebi mosques, and includes naves akin to a basilica . Those features can also be found in Andalusi mosques, including
