Frank H. Buhl Mansion , or Buhl Mansion , is a historic home located in Sharon, Pennsylvania , United States, that is listed on the National Register of Historic Places .
42-614: The mansion was built in 1891 for the Buhl family, which owned the Sharon Iron Works. The ashlar sandstone residence has 2 + 1 ⁄ 2 storeys. Noted Youngstown architect Charles Henry Owsley (1846–1935) designed it in the Richardsonian Romanesque style. The mansion features round arches, steep gable wall dormers, an inset porch with heavy arches, stone finials , and several turrets with copper capped spires. Although
84-522: A base of double-wall construction or larger boulders with single-wall construction above. They appear to be rickety, with many holes, which deters livestock (and people) from attempting to cross them. These dykes are principally found in locations with exceptionally high winds, where a solid wall might be at risk of being unsettled by the buffeting. The porous nature of the wall significantly reduces wind force but takes greater skill to construct. They are also found in grazing areas where they are used to maximize
126-414: A great many are still in use and maintained. New ones are often built in gardens and nature conservation areas. Dry stone retaining structures continue to be a subject of research. In northeastern Somalia , on the coastal plain 20 km (12 mi) to Aluula 's east are found ruins of an ancient monument in a platform style. The structure is formed by a rectangular dry stone wall that is low in height;
168-807: A joining material such as mortar to bind the blocks together, although dry ashlar construction, metal ties, and other methods of assembly have been used. The dry ashlar of Inca architecture in Cusco and Machu Picchu is particularly fine and famous. The word is attested in Middle English and derives from the Old French aisselier , from the Latin axilla , a diminutive of axis , meaning "plank". "Clene hewen ashler" often occurs in medieval documents; this means tooled or finely worked, in contradistinction to rough-axed faces. In tile carpet installation "ashlar" refers to
210-444: A type of single wall in which the wall consists primarily of large boulders, around which smaller stones are placed. Single walls work best with large, flatter stones. Ideally, the largest stones are being placed at the bottom and the whole wall tapers toward the top. Sometimes a row of capstones completes the top of a wall, with the long rectangular side of each capstone perpendicular to the wall alignment. Galloway dykes consist of
252-429: A vertical 1/2 offset pattern. Ashlar blocks have been used in the construction of many buildings as an alternative to brick or other materials. In classical architecture , ashlar wall surfaces were often contrasted with rustication . The term is frequently used to describe the dressed stone work of prehistoric Greece and Crete , although the dressed blocks are usually much larger than modern ashlar. For example,
294-405: Is a cut and dressed stone , worked using a chisel to achieve a specific form, typically rectangular in shape. The term can also refer to a structure built from such stones. Ashlar is the finest stone masonry unit, and is generally rectangular ( cuboid ). It was described by Vitruvius as opus isodomum or trapezoidal . Precisely cut "on all faces adjacent to those of other stones", ashlar
336-405: Is almost always used. One type of wall is called a "double" wall and is constructed by placing two rows of stones along the boundary to be walled. The foundation stones are ideally set into the ground so as to rest firmly on the subsoil . The rows are composed of large flattish stones, diminishing in size as the wall rises. Smaller stones may be used as chocks in areas where the natural stone shape
378-469: Is best known in the context of stone walls , traditionally used for the boundaries of fields and churchyards , or as retaining walls for terracing, but dry stone shelters, houses and other structures also exist. The term tends not to be used for the many historic styles which used precisely-shaped stone, but did not use mortar, for example the Greek temple and Inca architecture . The art of dry stone walling
420-399: Is capable of requiring only very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. One such decorative treatment consists of small grooves achieved by the application of a metal comb. Generally used only on softer stone ashlar, this decoration
462-683: Is known as "mason's drag". Ashlar is in contrast to rubble masonry , which employs irregularly shaped stones, sometimes minimally worked or selected for similar size, or both. Ashlar is related but distinct from other stone masonry that is finely dressed but not quadrilateral, such as curvilinear and polygonal masonry . Ashlar may be coursed , which involves lengthy horizontal layers of stone blocks laid in parallel, and therefore with continuous horizontal joints. Ashlar may also be random, which involves stone blocks laid with deliberately discontinuous courses and therefore discontinuous joints both vertically and horizontally. In either case, it generally uses

#1732884090038504-522: Is more rounded. The walls are built up to the desired height layer-by-layer ( course by course ) and, at intervals, large tie-stones or through stones are placed which span both faces of the wall and sometimes project. These have the effect of bonding what would otherwise be two thin walls leaning against each other, greatly increasing the strength of the wall. Diminishing the width of the wall as it gets higher, as traditionally done in Britain, also strengthens
546-530: Is offset by their sturdiness and consequent long, low-maintenance lifetimes. As a result of the increasing appreciation of the landscape and heritage value of dry stone walls, wallers remain in demand, as do the walls themselves. A nationally recognised certification scheme is operated in the UK by the Dry Stone Walling Association, with four grades from Initial to Master Craftsman. Notable examples include
588-457: The tholos tombs of Bronze Age Mycenae use ashlar masonry in the construction of the so-called "beehive" dome. This dome consists of finely cut ashlar blocks that decrease in size and terminate in a central capstone . These domes are not true domes, but are constructed using the corbel arch . Ashlar masonry was also heavily used in the construction of palace facades on Crete , including Knossos and Phaistos . These constructions date to
630-587: The Chambered cairn of Scotland . The cyclopean walls of the acropolis of Mycenae , Greece, have been dated to 1350 BC and those of Tiryns slightly earlier. Similar example is Daorson , in Bosnia , built around a prehistoric central fortified settlement or acropolis (existed there c. 17–16th C. BCE to the end of the Bronze Age , c. 9–8th C. BCE), and surrounded by cyclopean walls (similar to Mycenae ) dated to
672-622: The Liburnian era. Notable examples include the island of Baljenac, which has 23 kilometres (14 mi) of dry stone walls despite being only 14 hectares (35 acres) in area, and the vineyards of Primošten . In Peru in the 15th century AD, the Inca made use of otherwise unusable slopes by building dry stone walls to create terraces . They also employed this mode of construction for freestanding walls. Their ashlar type construction in Machu Picchu uses
714-458: The MM III-LM Ib period, c. 1700 –1450 BC. In modern European masonry the blocks are generally about 35 centimetres (14 in) in height. When shorter than 30 centimetres (12 in), they are usually called small ashlar . In some Masonic groupings, which such societies term jurisdictions , ashlars are used as a symbolic metaphor for how one's personal development relates to
756-748: The Mourne Wall , a 22-mile (35 km) wall in the Mourne Mountains in County Down , Northern Ireland , and the wall around the Ottenby nature reserve, built by Charles X Gustav in the mid-17th century in Öland , Sweden. While the dry stone technique is most commonly used for the construction of double-wall stone walls and single-wall retaining terracing, dry stone sculptures, buildings, fortifications, bridges, and other structures also exist. Traditional turf-roofed Highland blackhouses were constructed using
798-590: The United States they are common in areas with rocky soils, such as New England , New York , New Jersey , and Pennsylvania . They are a notable characteristic of the bluegrass region of central Kentucky , the Ozarks of Arkansas and Missouri , as well as Virginia , where they are usually referred to as rock fences or stone fences , and the Napa Valley in north central California . The technique of construction
840-880: The 4th C. BCE. In Belize , the Mayan ruins at Lubaantun illustrate use of dry stone construction in architecture of the 8th and 9th centuries AD. Great Zimbabwe in Zimbabwe , Africa, is an acropolis-like large city complex constructed in dry stone from the 11th to the 15th centuries AD. It is the largest of structures of similar construction throughout the area. Terminology varies regionally. When used as field boundaries, dry stone structures are more commonly known as dykes in Scotland , where professional dry stone wall builders are referred to as 'dykers'. Dry stone walls are characteristic of upland areas of Britain and Ireland where rock outcrops naturally or large stones exist in quantity in
882-562: The Freemason who, through education and diligence, has learned the lessons of Freemasonry and who lives an upstanding life. Dry stone Dry stone , sometimes called drystack or, in Scotland, drystane , is a building method by which structures are constructed from stones without any mortar to bind them together. A certain amount of binding is obtained through the use of carefully selected interlocking stones. Dry stone construction

#1732884090038924-633: The National Steel Co., which was itself eventually merged into the United States Steel Corporation shortly before Buhl's retirement. Buhl became known as the "Father of the Industrial Shenango Valley" and also founded Sharon Steel and Sharon Steel Castings (also merged into U.S. Steel). Buhl married Julia Forker, daughter of a prominent Sharon family. They had no children and became known for using their fortune to support
966-413: The base width. Different regions have made minor modifications to the general method of construction—sometimes because of limitations of building material available, but also to create a look that is distinctive for that area. Whichever method is used to build a dry stone wall, considerable skill is required. Correcting any mistakes invariably means disassembling down to the level of the error. Selection of
1008-424: The classic Inca architectural style of polished dry stone walls of regular shape. The Incas were masters of this technique, in which blocks of stone are cut to fit together tightly without mortar. Many junctions are so perfect that not even a knife fits between the stones. The structures have persisted in the high earthquake region because of the flexibility of the walls, and because in their double wall architecture,
1050-545: The community as a recreation center. In 1914, the F.H. Buhl Farm opened as a 300-acre park, complete with an 11-acre lake, beaches, 10 tennis courts, a nine-hole golf course , picnic groves, pavilions, playground and a baseball field. The mansion was added to the National Register of Historic Places in 1977 and featured in the 1988 film Tiger Warsaw .

1092-501: The coping stones on a final layer of flat stones slightly wider than the top of the wall proper ( coverbands ). In addition to gates, a wall may contain smaller purposely built gaps for the passage or control of wildlife and livestock such as sheep. The smaller holes usually no more than 200 millimetres (8 in) in height are called "Bolt Holes" or "Smoots". Larger ones may be between 450 and 600 mm (18 and 24 in) in height, which are called "Cripple Holes". Boulder walls are
1134-423: The correct stone for every position in the wall makes an enormous difference to the lifetime of the finished product, and a skilled waller will take time making the selection. As with many older crafts, skilled wallers, today, are few in number. With the advent of modern wire fencing, fields can be fenced with much less time and expense using wire than using stone walls; however, the initial expense of building dykes
1176-467: The double-wall dry stone method. When buildings are constructed using this method, the middle of the wall is generally filled with earth or sand in order to eliminate draughts. During the Iron Age, and perhaps earlier, the technique also was used to build fortifications such as the walls of Eketorp Castle ( Öland , Sweden ), Maiden Castle, North Yorkshire , Reeth , Dunlough Castle in southwest Ireland and
1218-535: The house had been converted to apartments, it was restored. It currently operates as a bed and breakfast and wedding venue. Yale-educated Frank H. Buhl (1848-1918) had returned in 1887 from Detroit , Michigan to help his father run the Iron Works, and in the following year, the Iron Works became Mercer County's largest employer. Buhl founded the Buhl Steel Company in 1896, which three years later merged into
1260-444: The mountain river of Vydra) are often lined by dry stone walls built of field-stones removed from the arable or cultural land. They serve both as cattle/sheep fences and the lot's borders. Sometimes also the dry stone terracing is apparent, often combined with parts of stone masonry (house foundations and shed walls) that are held together by a clay and pine needle "composite" mortar . The dry stone walling tradition of Croatia
1302-486: The rampart of the Long Scar Dyke. Many of the dry-stone walls that exist today in Scotland can be dated to the 14th century or earlier when they were built to divide fields and retain livestock. Some extremely well built examples are found on the lands of Muchalls Castle . Dry stone walls can be built against embankments or even vertical terraces. If they are subjected to lateral earth pressure, they are retaining walls of

1344-632: The soil. They are especially abundant in the West of Ireland, particularly Connemara . They may also be found throughout the Mediterranean , including retaining walls used for terracing. Such constructions are common where large stones are plentiful (for example, in The Burren ) or conditions are too harsh for hedges capable of retaining livestock to be grown as reliable field boundaries. Many thousands of kilometres of such walls exist, most of them centuries old. In
1386-456: The space in between is filled with rubble and manually covered with small stones. Relatively large standing stones are also positioned on the edifice's corners. Near the platform are graves, which are outlined in stones. Measuring 24 by 17 m (79 by 56 ft), the structure is the largest of a string of ancient platform and enclosed platform monuments exclusive to far northeastern Somalia. In Great Britain, Ireland, France and Switzerland, it
1428-539: The surrounding community. Buhl's father had founded the Christian H. Buhl hospital (now the Sharon Regional Hospital). Frank Buhl established the F.H. Buhl club, opened to all Sharon citizens in 1903, and located between this building and the city's downtown. It held music and social rooms, bowling alleys, billiard and games rooms, and a library. It merged with a women's club founded by Julia Buhl, and still serves
1470-536: The tenets of their lodge . As described in the explanation of the First Degree Tracing Board , in Emulation and other Masonic rituals the rough ashlar is a stone as taken directly from the quarry, and allegorically represents the Freemason prior to his initiation; a smooth ashlar (or "perfect ashlar") is a stone that has been smoothed and dressed by the experienced stonemason , and allegorically represents
1512-407: The two portions of the walls incline into each other. The style and method of construction of a wall will vary, depending on the type of stone available, its intended use and local tradition. Many older walls were constructed from stones and boulders cleared from the fields during preparation for agriculture ( field stones ) although some used stone quarried nearby. For modern walls, quarried stone
1554-434: The type gravity wall. The weight of the stones resists the pressure from the retained soil, including any surcharges, and the friction between the stones causes most of them to act as if they were a monolithic gravity wall of the same weight. Dry stone retaining walls were once built in great numbers for agricultural terracing and also to carry paths, roads and railways. Although dry stone is seldom used for these purposes today,
1596-454: The utility of the available stones (where ploughing was not turning up ever more stones). Another variation is the Cornish hedge or Welsh clawdd , which is a stone-clad earth bank topped by turf, scrub, or trees and characterised by a strict inward-curved batter (the slope of the "hedge"). As with many other varieties of wall, the height is the same as the width of the base, and the top is half
1638-415: The wall considerably. The voids between the facing stones are carefully packed with smaller stones ( filling , hearting ). The final layer on the top of the wall also consists of large stones, called capstones , coping stones or copes . As with the tie stones, the capstones span the entire width of the wall and prevent it breaking apart. In some areas, such as South Wales, there is a tradition of placing
1680-598: Was added to the UNESCO Representative List of the Intangible Cultural Heritage of Humanity in November 2018, alongside those of Cyprus, France, Greece, Italy, Slovenia, Spain and Switzerland. In Croatia, dry stone walls ( suhozidi ) were built for a variety of reasons: to clear the earth of stone for crops; to delineate land ownership; or for shelter against the bora wind. Some walls date back to
1722-669: Was brought to America primarily by English and Scots-Irish immigrants. The technique was also taken to Australia (principally western Victoria , some parts of Tasmania , and some parts of New South Wales , particularly around Kiama ) and New Zealand (especially Otago ). Similar walls also are found in the Swiss–Italian border region, where they are often used to enclose the open space under large natural boulders or outcrops. The higher-lying rock-rich fields and pastures in Bohemia 's south-western border range of Šumava (e.g. around

1764-677: Was inscribed in 2018 on the UNESCO representative list of the intangible cultural heritage of humanity , for dry stone walls in countries such as France , Greece , Italy , Slovenia , Croatia , Switzerland and Spain . Some dry stone wall constructions in north-west Europe have been dated back to the Neolithic Age. In County Mayo , Ireland, an entire field system made from dry stone walls, since covered in peat, has been carbon-dated to 3800 BC. These are near contemporary with the, dry stone constructed, neolithic village of Skara Brae , and
