Clerestory Roof
In architecture, a clerestory ( ; , also clearstory, clearstorey, or overstorey) is a high section of wall that contains windows above eye level. Its purpose is to admit light, fresh air, or both. Historically, ''clerestory'' denoted an upper level of a Roman basilica or of the nave of a Romanesque or Gothic church, the walls of which rise above the rooflines of the lower aisles and are pierced with windows. Similar structures have been used in transportation vehicles to provide additional lighting, ventilation, or headroom. History Ancient world The technology of the clerestory appears to originate in the temples of ancient Egypt. The term "clerestory" is applicable to Egyptian temples, where the lighting of the hall of columns was obtained over the stone roofs of the adjoining aisles, through gaps left in the vertical slabs of stone. Clerestory appeared in Egypt at least as early as the Amarna period. In the Minoan palaces of Crete such as Knossos, by contrast, lightwel ...

Lightwell
In architecture, a lightwell,light well, light-well sky-well,skywell, sky well or air shaft is an unroofed or roofed external space provided within the volume of a large building to allow light and air to reach what would otherwise be a dark or unventilated area. Lightwells may be lined with glazed bricks to increase the reflection of sunlight within the space. Lightwells may have sunlight reflecting mirrors on the top of light well. Lightwells serve to reduce the necessity for electric lighting, add a central space within the building, and provide an internal open space for windows to give an illusion of having a view outside. Area or areaway A subterranean lightwell by any frontage of a building for light to a basement is also called an area (or areaway in North American usage). Ancient history The lightwell was used in ancient civilizations, such as the Egyptians and at the Palace of Knossos on Minoan Crete. There are also instances of lightwell use by the Romans, the impl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bavaria
Bavaria ( ; ), officially the Free State of Bavaria (german: Freistaat Bayern, link=no ), is a state in the south-east of Germany. With an area of , Bavaria is the largest German state by land area, comprising roughly a fifth of the total land area of Germany. With over 13 million inhabitants, it is second in population only to North Rhine-Westphalia, but due to its large size its population density is below the German average. Bavaria's main cities are Munich (its capital and largest city and also the third largest city in Germany), Nuremberg, and Augsburg. The history of Bavaria includes its earliest settlement by Iron Age Celtic tribes, followed by the conquests of the Roman Empire in the 1st century BC, when the territory was incorporated into the provinces of Raetia and Noricum. It became the Duchy of Bavaria (a stem duchy) in the 6th century AD following the collapse of the Western Roman Empire. It was later incorporated into the Holy Roman Empire, became an ind ...

Augsburg Cathedral
The Cathedral of Augsburg (German: ''Dom Mariä Heimsuchung'') is a Roman Catholic church in Augsburg, Bavaria, Germany, founded in the 11th century in Romanesque style, but with 14th-century Gothic additions. Together with the Basilica of St. Ulrich and Afra, it is one of the city's main attractions. It measures 113 x 40 m, and its towers are 62 m high. It is dedicated to the Visitation of Virgin Mary. History The cathedral is perhaps located on the site of a pre-existing 4th-century building, not necessarily a church, whose foundations have been excavated beneath the current level; the site is included within the ancient Roman walls of ''Augusta Vindelicorum''. The first known church in the place is documented from 822, but dating to the late 8th century reigns of bishops Wikterp and Simpert. The edifice was damaged by the Magyars and was restored in 923 under bishop Ulrich. Another repairing intervention occurred in 994 when the western apse crumbled down; the re ...

Triforium
A triforium is an interior gallery, opening onto the tall central space of a building at an upper level. In a church, it opens onto the nave from above the side aisles; it may occur at the level of the clerestory windows, or it may be located as a separate level below the clerestory. Masonry triforia are generally vaulted and separated from the central space by arcades. Early triforia were often wide and spacious, but later ones tend to be shallow, within the thickness of an inner wall, and may be blind arcades not wide enough to walk along. The outer wall of the triforium may itself have windows (glazed or unglazed openings), or it may be solid stone. A narrow triforium may also be called a "blind-storey", and looks like a row of window frames. History ''Triforium'' is derived from the Latin ''tres'', ''tria'' "three", and ''foris'', "door, entrance"; its Greek equivalent is τρίθυρον, which originally referred to a building with three doors.

Arcade (architecture)
An arcade is a succession of contiguous arches, with each arch supported by a colonnade of columns or piers. Exterior arcades are designed to provide a sheltered walkway for pedestrians. The walkway may be lined with retail stores. An arcade may feature arches on both sides of the walkway. Alternatively, a blind arcade superimposes arcading against a solid wall. Blind arcades are a feature of Romanesque architecture that influenced Gothic architecture. In the Gothic architectural tradition, the arcade can be located in the interior, in the lowest part of the wall of the nave, supporting the triforium and the clerestory in a cathedral, or on the exterior, in which they are usually part of the walkways that surround the courtyard and cloisters. Many medieval arcades housed shops or stalls, either in the arcaded space itself, or set into the main wall behind. From this, "arcade" has become a general word for a group of shops in a single building, regardless of the architectural f ...

Ribbed Vault
A rib vault or ribbed vault is an architectural feature for covering a wide space, such as a church nave, composed of a framework of crossed or diagonal arched ribs. Variations were used in Roman architecture, Byzantine architecture, Islamic architecture, Romanesque architecture, and especially Gothic architecture. Thin stone panels fill the space between the ribs. This greatly reduced the weight and thus the outward thrust of the vault. The ribs transmit the load downward and outward to specific points, usually rows of columns or piers. This feature allowed architects of Gothic cathedrals to make higher and thinner walls and much larger windows. It is a type of arcuated, or arched, vault in which the severies, or panels in the bays of the vault's underside are separated from one another by ribs which conceal the groins, or the intersections of the panels. Rib vaults are, like groin vaults, formed from two or three intersecting barrel vaults; the ribs conceal the junction of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groin Vault
A groin vault or groined vault (also sometimes known as a double barrel vault or cross vault) is produced by the intersection at right angles of two barrel vaults. Honour, H. and J. Fleming, (2009) ''A World History of Art''. 7th edn. London: Laurence King Publishing, p. 949. The word "groin" refers to the edge between the intersecting vaults. Sometimes the arches of groin vaults are pointed instead of round. In comparison with a barrel vault, a groin vault provides good economies of material and labor. The thrust is concentrated along the groins or arrises (the four diagonal edges formed along the points where the barrel vaults intersect), so the vault need only be abutted at its four corners. Groin vault construction was first exploited by the Romans, but then fell into relative obscurity in Europe until the resurgence of quality stone building brought about by Carolingian and Romanesque architecture. It was superseded by the more flexible rib vaults of Gothic architectur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrel-vaulted
A barrel vault, also known as a tunnel vault, wagon vault or wagonhead vault, is an architectural element formed by the extrusion of a single curve (or pair of curves, in the case of a pointed barrel vault) along a given distance. The curves are typically circular in shape, lending a semi-cylindrical appearance to the total design. The barrel vault is the simplest form of a vault: effectively a series of arches placed side by side (i.e., one after another). It is a form of barrel roof. As with all arch-based constructions, there is an outward thrust generated against the walls underneath a barrel vault. There are several mechanisms for absorbing this thrust. One is to make the walls exceedingly thick and strong – this is a primitive and sometimes unacceptable method. A more elegant method is to build two or more vaults parallel to each other; the forces of their outward thrusts will thus negate each other. This method was most often used in construction of churches, where sev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malmesbury
Malmesbury () is a town and civil parish in north Wiltshire, England, which lies approximately west of Swindon, northeast of Bristol, and north of Chippenham. The older part of the town is on a hilltop which is almost surrounded by the upper waters of the Bristol Avon and one of its tributaries. Once the site of an Iron Age fort, in the early medieval period Malmesbury became the site Malmesbury Abbey, a monastery famed for its learning. It was later home to one of Alfred the Great's fortified burhs for defence against the Vikings. Æthelstan, the first king of all England, was buried in Malmesbury Abbey when he died in 939. As a market town, it became prominent in the Middle Ages as a centre for learning, focused on and around the abbey. In modern times, Malmesbury is best known for its abbey, the bulk of which forms a rare survival of the dissolution of the monasteries. The economy benefits mostly from agriculture, as well as tourism to the Cotswolds, and a Dyson facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Christianity
Early Christianity (up to the First Council of Nicaea in 325) spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora. The first followers of Christianity were Jews or proselytes, commonly referred to as Jewish Christians and God-fearers. The Apostolic sees claim to have been founded by one or more of the apostles of Jesus, who are said to have dispersed from Jerusalem sometime after the crucifixion of Jesus, c. 26–36, perhaps following the Great Commission. Early Christians gathered in small private homes, known as house churches, but a city's whole Christian community would also be called a church – the Greek noun ἐκκλησία (''ekklesia'') literally means assembly, gathering, or congregation but is translated as church in most English translations of the New Testament. Many early Christians were merchants and others who had prac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greeks
Ancient Greece ( el, Ἑλλάς, Hellás) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity ( AD 600), that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC (though this excludes a number of Greek city-states free from Alexander's jurisdiction in the western Mediterranean, around the Black Sea, Cyprus, and Cyrenaica). In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
