Buttresses
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient (typically Gothic) buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L-shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses a ...

Gothic Architecture
Gothic architecture is an architectural style that was prevalent in Europe from the late 12th to the 16th century, during the High Middle Ages, High and Late Middle Ages, surviving into the 17th and 18th centuries in some areas. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. It originated in the Île-de-France and Picardy regions of northern France. The style at the time was sometimes known as ''opus Francigenum'' (); the term ''Gothic'' was first applied contemptuously during the later Renaissance, by those ambitious to revive the Classical architecture, architecture of classical antiquity. The defining design element of Gothic architecture is the Pointed arch (architecture), pointed arch. The use of the pointed arch in turn led to the development of the pointed rib vault and flying buttresses, combined with elaborate tracery and stained glass windows. At the Abbey of Basilica of Saint-Denis, Saint-Denis, near Paris, the choir was rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Buttress
The flying buttress (''arc-boutant'', arch buttress) is a specific form of buttress composed of a ramping arch that extends from the upper portion of a wall to a pier of great mass, to convey to the ground the lateral forces that push a wall outwards, which are forces that arise from vaulted ceilings of stone and from wind-loading on roofs. The namesake and defining feature of a flying buttress is that it is not in contact with the wall at ground level, unlike a traditional buttress, and transmits the lateral forces across the span of intervening space between the wall and the pier. To provide lateral support, flying-buttress systems are composed of two parts: (i) a massive pier, a vertical block of masonry situated away from the building wall, and (ii) an arch that bridges the span between the pier and the wall – either a segmental arch or a quadrant arch – the ''flyer'' of the flying buttress. History As a lateral-support system, the flying buttress was developed duri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paoay Church
Saint Augustine Parish Church, commonly known as Paoay Church, is a Roman Catholic church in the municipality of Paoay, Ilocos Norte in the Philippines. It is under the ecclesiastical jurisdiction of the Diocese of Laoag. Completed in 1710, the church is famous for its distinctive architecture, a highlight of which are the enormous buttresses on the sides and the back of the building. It is declared as a National Cultural Treasure by the Philippine government in 1973 and a UNESCO World Heritage Site under the collective group of Baroque Churches of the Philippines in 1993. History The earliest historical record of the area dates back to 1593, becoming an independent Augustinian parish by 1686. The construction of the present church was started in 1694 by Augustinian friar Father Antonio Estavillo and was completed in 1710. It was later on rededicated in 1896. Some portions of the church were damaged in the 1865 and 1885 earthquakes but was later restored under the initia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquake Baroque
Earthquake Baroque, or Seismic Baroque, is a style of Baroque architecture found in the Philippines and in Guatemala, which were Spanish-ruled territories that suffered destructive earthquakes during the 17th and the 18th centuries. Large public buildings, such as churches, were then rebuilt in a Baroque style during the Spanish colonial periods in those countries. Similar events led to the Pombaline architecture in Lisbon following the 1755 Lisbon earthquake and Sicilian Baroque in Sicily following the 1693 earthquake. Characteristics In the Spanish East Indies, destruction of earlier churches from frequent earthquakes have made the church proportion lower and wider; side walls were made thicker and heavily buttressed for stability during shaking. The upper structures were made with lighter materials. Instead of lighter materials thinner walls were introduced by progressively decreasing in thickness to the topmost levels. Bell towers are usually lower and stouter compared ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cathedral Architecture
Cathedrals, collegiate churches, and monastic churches like those of abbeys and priories, often have certain complex structural forms that are found less often in parish churches. They also tend to display a higher level of contemporary architectural style and the work of accomplished craftsmen, and occupy a status both ecclesiastical and social that an ordinary parish church rarely has. Such churches are generally among the finest buildings locally and a source of regional pride. Many are among the world's most renowned works of architecture. These include St Peter's Basilica, Notre-Dame de Paris, Cologne Cathedral, Salisbury Cathedral, Antwerp Cathedral, Prague Cathedral, Lincoln Cathedral, the Basilica of Saint-Denis, Santa Maria Maggiore, the Basilica of San Vitale, St Mark's Basilica, Westminster Abbey, Saint Basil's Cathedral, Antoni Gaudí's incomplete Sagrada Família and the ancient cathedral of Hagia Sophia in Istanbul, now a mosque.

Milan Cathedral
Milan Cathedral ( ; ), or Metropolitan Cathedral-Basilica of the Nativity of Saint Mary (), is the cathedral church of Milan, Lombardy, Italy. Dedicated to the Nativity of Mary, Nativity of St. Mary (), it is the seat of the Roman Catholic Archdiocese of Milan, Archbishop of Milan, currently Archbishop Mario Delpini. The cathedral took nearly six centuries to complete: construction began in 1386, and the final details were completed in 1965. It 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 one of largest in the world. History Milan's layout, with streets either radiating from the Duomo or circling it, reveals that the Duomo occupies what was the most central site in Mediolanum, Roman Mediolanum, that of the public basilica facing the Forum (Roman), forum. The Santa Tecla, Milan, first cathedral, the "new basilica" (') dedicated to Saint Thecla, St Thecla, was completed by 355. It seem ...

Castle Architecture
A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars usually consider a ''castle'' to be the private fortified residence of a lord or noble. This is distinct from a mansion, palace, and villa, whose main purpose was exclusively for ''pleasance'' and are not primarily fortresses but may be fortified. Use of the term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the Middle Ages, when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls, arrowslits, and portcullises, were commonplace. European-style castles originated in the 9th and 10th centuries after the fall of the Carolingian Empire, which resulted in its territory being divided among individual lords and princes. These nobles built castle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fortification (architectural Elements)
A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted as a ...

Retaining Wall
Retaining walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope). They are used to bound soils between two different elevations often in areas of inconveniently steep terrain in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses. A retaining wall that retains soil on the backside and water on the frontside is called a seawall or a bulkhead. Definition A retaining wall is designed to hold in place a mass of earth or the like, such as the edge of a terrace or excavation. The structure is constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. A basement wall is thus one k ...

Pilaster
In architecture, a pilaster is both a load-bearing section of thickened wall or column integrated into a wall, and a purely decorative element in classical architecture which gives the appearance of a supporting column and articulates an extent of wall. As an ornament it consists of a flat surface raised from the main wall surface, usually treated as though it were a column, with a capital at the top, plinth (base) at the bottom, and the various other column elements. In contrast to a Classical pilaster, an engaged column or buttress can support the structure of a wall and roof above. In human anatomy, a pilaster is a ridge that extends vertically across the femur, which is unique to modern humans. Its structural function is unclear. Definition A pilaster is foremost a load-bearing architectural element used widely throughout the world and its history where a structural load is carried by a thickened section of wall or column integrated into a wall. It is also a purel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columns And Entablature
A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. The term ''column'' applies especially to a large round support (the shaft of the column) with a capital and a base or pedestal, which is made of stone, or appearing to be so. A small wooden or metal support is typically called a ''post''. Supports with a rectangular or other non-round section are usually called '' piers''. For the purpose of wind or earthquake engineering, columns may be designed to resist lateral forces. Other compression members are often termed "columns" because of the similar stress conditions. Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest. In architecture, "column" refers to such a structural element that also has certain proportional and decorative featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
