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.
Gothic architecture is an architectural style that was prevalent in Europe from the late 12th to the 16th century, during the 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 architecture of classical antiquity.
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.
An ogive is the roundly tapered end of a two- or three-dimensional object. Ogive curves and surfaces are used in engineering, architecture, woodworking, and ballistics.
The flying 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, in order 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.
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.
The term Norman architecture is used to categorise styles of Romanesque architecture developed by the Normans in the various lands under their dominion or influence in the 11th and 12th centuries. In particular the term is traditionally used for English Romanesque architecture. The Normans introduced large numbers of castles and fortifications including Norman keeps, and at the same time monasteries, abbeys, churches and cathedrals, in a style characterised by the usual Romanesque rounded arches and especially massive proportions compared to other regional variations of the style.
Tracery is an architectural device by which windows are divided into sections of various proportions by stone bars or ribs of moulding. Most commonly, it refers to the stonework elements that support the glass in a window. The purpose of the device is practical as well as decorative, because the increasingly large windows of Gothic buildings needed maximum support against the wind. The term probably derives from the tracing floors on which the complex patterns of windows were laid out in late Gothic architecture. Tracery can be found on the exterior of buildings as well as the interior.
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.
A four-centred arch or four-centered arch is a low, wide type of arch with a pointed apex. Its structure is achieved by drafting two arcs which rise steeply from each springing point on a small radius, and then turning into two arches with a wide radius and much lower springing point. It is a pointed sub-type of the general flattened depressed arch. This type of arch uses space efficiently and decoratively when used for doorways. It is also employed as a wall decoration in which arcade and window openings form part of the whole decorative surface. Two of the most notable types are known as the Persian arch, which is moderately "depressed" and found in Islamic architecture, and the Tudor arch, which is much flatter and found in English architecture. Another variant, the keel arch, has partially straight rather than curved sides and developed in Fatimid architecture.
French architecture consists of architectural styles that either originated in France or elsewhere and were developed within the territories of France.
Spanish Gothic architecture is the style of architecture prevalent in Spain in the Late Medieval period.
Early Gothic is the term for the first period of Gothic architecture which lasted from about 1120 until about 1200. The early Gothic builders used innovative technologies to resolve the problem of masonry ceilings which were too heavy for the traditional arched barrel vault. The solutions to the problem came in the form of the rib vault, where thin stone ribs passed the weight of the ceiling to rows of columns and outside the walls to another innovation, the flying buttress.
The Primatial Cathedral of Tarragona is a Roman Catholic church in Tarragona, Catalonia, Spain. The edifice is located in a site previously occupied by a Roman temple dating to the time of Tiberius, a Visigothic cathedral, and a Moorish mosque. It was declared a national monument in 1905.
Romanesque architecture in Spain is the architectural style reflective of Romanesque architecture, with peculiar influences both from architectural styles outside the Iberian Peninsula via Italy and France as well as traditional architectural patterns from within the peninsula. Romanesque architecture was developed in and propagated throughout Europe for more than two centuries, ranging approximately from the late tenth century until the thirteenth century.
Interlaced arches is a scheme of decoration employed in Romanesque and Gothic architecture, where arches spring from alternate piers, interlacing or intersecting one another. In the former case, the first arch archivolt is carried alternately over and under the second, in the latter the archivolts actually intersect and stop one another. An example of the former exists in St Peter-in-the-East in Oxford and of the latter in St. Joseph’s chapel in Glastonbury, and in the Bristol Cathedral. The arches in the interlacing arcade can be either semicircular or pointed, and usually form purely decorative blind arcades.
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.
In architecture, a semicircular arch is an arch with an intrados shaped like a semicircle. This type of arch was adopted and very widely used by the Romans, thus becoming permanently associated with Roman architecture.
