Triangular Arch
In architecture, a triangular arch (sometimes ''angular arch'') typically defines an arch where the intrados (inner surface of an arch) consists of two straight segments formed by two stone slabs leaning against each other. In this roof-like arrangement, mitre joint is usually used at the Crown (arch), crown, thus the arch was in the past also called a ''mitre arch''. Brick builders would call triangular any arch with straight inclined sides. Maya civilization, Mayan corbel arches are also sometimes called triangular due to their shape. Since the sides of a triangular arch are experiencing bending stress, it is a false arch in a structural sense (historically preceding the invention of true arches and going back to Neolithic times). The design was used in Anglo-Saxon England until the late 11th century (St Mary Goslany) over small openings.

True Arch
An arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of vaults, with the barrel vault in particular being a continuous arch. Extensive use of arches and vaults characterizes an arcuated construction, as opposed to the trabeated system, where, like in the architectures of ancient Greece, China, and Japan (as well as the modern steel-framed technique), posts and beams dominate. Arches had several advantages over the lintel, especially in the masonry construction: with the same amount of material it can have large ...

Pediment
Pediments are a form of gable in classical architecture, usually of a triangular shape. Pediments are placed above the horizontal structure of the cornice (an elaborated lintel), or entablature if supported by columns.Summerson, 130 In ancient architecture, a wide and low triangular pediment (the side angles 12.5° to 16°) typically formed the top element of the portico of a Greek temple, a style continued in Roman temples. But large pediments were rare on other types of building before Renaissance architecture. For symmetric designs, it provides a center point and is often used to add grandness to entrances. The cornice continues round the top of the pediment, as well as below it; the rising sides are often called the "raking cornice". The tympanum is the triangular area within the pediment, which is often decorated with a pedimental sculpture which may be freestanding or a relief sculpture. The tympanum may hold an inscription, or in modern times, a clock face. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglo-Saxon Architecture
Anglo-Saxon architecture was a period in the history of architecture in England from the mid-5th century until the Norman Conquest of 1066. Anglo-Saxon secular buildings in Britain were generally simple, constructed mainly using timber with thatch for roofing. No universally accepted example survives above ground. Generally preferring not to settle within the old Roman cities, the Anglo-Saxons built small towns near their centres of agriculture, at fords in rivers or sited to serve as ports. In each town, a main hall was in the centre, provided with a central hearth. There are many remains of Anglo-Saxon church architecture. At least fifty churches are of Anglo-Saxon origin with major Anglo-Saxon architectural features, with many more claiming to be, although in some cases the Anglo-Saxon part is small and much-altered. It is often impossible to reliably distinguish between pre- and post-Conquest 11th century work in buildings where most parts are later additions or alterations. T ...

St Peter's Church, Barton-upon-Humber
St Peter's Church is the former parish church of Barton-upon-Humber in North Lincolnshire, England. It is one of the best known Anglo-Saxon buildings, in part due to its role in Thomas Rickman's identification of the style. It has been subject to major excavations. The former Church of England church is now run by English Heritage and houses an exhibition exploring its history. Origins The church lies immediately east of the remains of a near circular enclosure which contained a hall. This is, on average, in diameter and was originally surrounded by a ditch and timber palisade known to date to before 900. An early pagan Saxon cemetery, believed to be linked with this enclosure and dated to the first half of the seventh century, was discovered at Castledyke, south of the church, and was used to bury high-status individuals. In 669 Saint Chad founded a monastery in neighbouring Barrow-upon-Humber. An Anglo-Saxon charter dated 971 suggests that Barton became a grange ...

White Castle, Monmouthshire
White Castle (), also known historically as Llantilio Castle, is a ruined castle near the village of Llantilio Crossenny in Monmouthshire, Wales. The fortification was established by the Normans in the wake of the invasion of England in 1066, to protect the route from Wales to Hereford. Possibly commissioned by William fitz Osbern, the Earl of Hereford, it comprised three large earthworks with timber defences. In 1135, a major Welsh revolt took place and in response King Stephen brought together White Castle and its sister fortifications of Grosmont and Skenfrith to form a lordship known as the " Three Castles", which continued to play a role in defending the region from Welsh attack for several centuries. King John gave the castle to a powerful royal official, Hubert de Burgh, in 1201. Over the next few decades, it passed back and forth between several owners, as Hubert, the rival de Braose family, and the Crown took control of the property. During this period, White Castl ...

Masonry
Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound, and pasted together by mortar (masonry), mortar. The term ''masonry'' can also refer to the building units (stone, brick, etc.) themselves. The common materials of masonry construction are bricks and building stone, rock (geology), rocks such as marble, granite, and limestone, cast stone, concrete masonry unit, concrete blocks, glass brick, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction worker, construction trades. History Masonry is one of the oldest building crafts in the world. The constructio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglo-Saxon England
Anglo-Saxon England or early medieval England covers the period from the end of Roman Empire, Roman imperial rule in Roman Britain, Britain in the 5th century until the Norman Conquest in 1066. Compared to modern England, the territory of the Anglo-Saxons stretched north to present day Lothian in southeastern Scotland, whereas it did not initially include western areas of England such as Cornwall, Herefordshire, Shropshire, Cheshire, Lancashire, and Cumbria. The 5th and 6th centuries involved the collapse of economic networks and political structures and also saw a radical change to a new Anglo-Saxon language and culture. This change was driven by movements of peoples as well as changes which were happening in both northern Gaul and the North Sea coast of what is now Germany and the Netherlands. The Anglo-Saxon language, also known as Old English, was a close relative of languages spoken in the latter regions, and genetic studies have confirmed that there was significant migrat ...

Neolithic
The Neolithic or New Stone Age (from Ancient Greek, Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the History of agriculture, introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of sedentism, settlement. The term 'Neolithic' was coined by John Lubbock, 1st Baron Avebury, Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development ...

Architecture
Architecture is the art and technique of designing and building, as distinguished from the skills associated with construction. It is both the process and the product of sketching, conceiving, planning, designing, and construction, constructing buildings or other Structure#Load-bearing, structures. The term comes ; ; . Architectural works, in the material form of buildings, are often perceived as cultural symbols and as work of art, works of art.
