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.
Romanesque architecture is an architectural style of medieval Europe that was predominant in the 11th and 12th centuries. The style eventually developed into the Gothic style with the shape of the arches providing a simple distinction: the Romanesque is characterized by semicircular arches, while the Gothic is marked by the pointed arches. The Romanesque emerged nearly simultaneously in multiple countries ; its examples can be found across the continent, making it the first pan-European architectural style since Imperial Roman architecture. Similarly to Gothic, the name of the style was transferred onto the contemporary Romanesque art.
A dome is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them.
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.
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.
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 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. It is a form of barrel roof.
A groin vault or groined vault is produced by the intersection at right angles of two barrel vaults. 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, so the vault need only be abutted at its four corners.
Speyer Cathedral, officially the Imperial Cathedral Basilica of the Assumption and St Stephen, in Latin: Domus sanctae Mariae Spirae in Speyer, Germany, is the seat of the Roman Catholic Bishop of Speyer and is suffragan to the Roman Catholic Archdiocese of Bamberg. The cathedral, which is dedicated to St. Mary, patron saint of Speyer and St. Stephen is generally known as the Kaiserdom zu Speyer. Pope Pius XI raised Speyer Cathedral to the rank of a minor basilica of the Roman Catholic Church in 1925.
The Abbey of Fontenay is a former Cistercian abbey located in the commune of Marmagne, near Montbard, in the département of Côte-d'Or in France. It was founded by Saint Bernard of Clairvaux in 1118, and built in the Romanesque style. It is one of the oldest and most complete Cistercian abbeys in Europe, and became a UNESCO World Heritage Site in 1981. Of the original complex comprising church, dormitory, cloister, chapter house, caldarium, refectory, dovecote and forge, all remain intact except the refectory and are well maintained. The Abbey of Fontenay, along with other Cistercian abbeys, forms a connecting link between Romanesque and Gothic architecture.
In architecture, a vault is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. Until the topmost voussoir, the keystone, is positioned, the vault is not self-supporting. Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or segmental head, which supports the voussoirs until the ring of the whole arch is completed.
The Plantagenet style or Angevine Gothic is an architectural style of western France, mainly of the second half of 12th and the 13th century. By Eugène Viollet-le-Duc it was called "Style ogivale Plantagenêt", something like "Plantagenet Ribs Style". It is named by the House of Anjou-Plantagenet. It is characterized by cross-ribbed vaults and extremely curved relatively domelike vaults.
Domes built in the 16th, 17th, and 18th centuries relied primarily on empirical techniques and oral traditions rather than the architectural treatises of the time, but the study of dome structures changed radically due to developments in mathematics and the study of statics. Analytical approaches were developed and the ideal shape for a dome was debated, but these approaches were often considered too theoretical to be used in construction.
The Basilica of the Assumption of Our Lady in Old Brno Abbey is a high Gothic, monumental convent temple. It was founded in 980-1020 by the unknown lord or monarch in Moravia. It was built on the site of an ancient sanctuary from the late 10th century in a short time in the years 1323 to 1334 at the instigation of Queen Elizabeth Richeza. It is the best preserved stylistically coherent and unified temple in Lands of Bohemian Crown.
St. Castulus church is a Gothic church with Romanesque and Baroque elements. It is located on the Castulus square, in Old town near Convent of Saint Agnes. It is the only church in the Czech Republic consecrated to Saint Castulus.
Romanesque architecture appeared in France at the end of the 10th century, with the development of feudal society and the rise and spread of monastic orders, particularly the Benedictines, which built many important abbeys and monasteries in the style. It continued to dominate religious architecture until the appearance of French Gothic architecture in the Île-de-France between about 1140 and 1150.
A pointed arch, ogival arch, or Gothic arch is an arch with a pointed crown meet at an angle at the top of the arch. Also known as a two-centred arch, its form is derived from the intersection of two circles. This architectural element was particularly important in Gothic architecture. The earliest use of a pointed arch dates back to bronze-age Nippur. As a structural feature, it was first used in eastern Christian architecture, Byzantine architecture and Sasanian architecture, but in the 12th century it came into use in France and England as an important structural element, in combination with other elements, such as the rib vault and later the flying buttress. These allowed the construction of cathedrals, palaces and other buildings with dramatically greater height and larger windows which filled them with light.
Alternation of supports is a trait of Romanesque architecture, where the supports in a colonnade or arcade have different types. For example, periodic change between the strong supports (piers) and the weak ones (columns) provides visually obvious alternating supports. More subtle alternation can result, for example, from variations of the column shafts.
The ramping arch is an asymmetrical arch that has its springers located at substantially different heights. Frequently a ramping arch is associated with a ramp or stairs.
