Groin vaultA 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. 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.
Fan vaultA fan vault is a form of vault used in the Gothic style, in which the ribs are all of the same curve and spaced equidistantly, in a manner resembling a fan. The initiation and propagation of this design element is strongly associated with England. The earliest example, dating from about the year 1351, may be seen in the cloisters of Gloucester Cathedral. The largest fan vault in the world can be found in King's College Chapel, Cambridge. The fan vault is peculiar to England.
Wells CathedralWells Cathedral is an Anglican cathedral in Wells, Somerset, England, dedicated to St Andrew the Apostle. It is the seat of the Bishop of Bath and Wells, whose cathedra it holds as mother church of the Diocese of Bath and Wells. Built as a Roman Catholic cathedral from around 1175 to replace an earlier church on the site since 705, it became an Anglican cathedral when King Henry VIII split from Rome. It is moderately sized for an English cathedral. Its broad west front and large central tower are dominant features.
Notre-Dame de ParisNotre-Dame de Paris (nɔtʁ(ə) dam də paʁi; meaning "Our Lady of Paris"), referred to simply as Notre-Dame, is a medieval Catholic cathedral on the Île de la Cité (an island in the Seine River), in the 4th arrondissement of Paris, France. The cathedral, dedicated to the Virgin Mary, is considered one of the finest examples of French Gothic architecture. Several attributes set it apart from the earlier Romanesque style, particularly its pioneering use of the rib vault and flying buttress, its enormous and colourful rose windows, and the naturalism and abundance of its sculptural decoration.
Bay (architecture)In architecture, a bay is the space between architectural elements, or a recess or compartment. The term bay comes from Old French baie, meaning an opening or hole. NOTOC The spaces between posts, columns, or buttresses in the length of a building, the division in the widths being called aisles. This meaning also applies to overhead vaults (between ribs), in a building using a vaulted structural system. For example, the Gothic architecture period's Chartres Cathedral has a nave (main interior space) that is "seven bays long.
Pier (architecture)A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers. External or free-standing walls may have piers at the ends or on corners. The simplest cross section of the pier is square, or rectangular, but other shapes are also common. In medieval architecture, massive circular supports called drum piers, cruciform (cross-shaped) piers, and compound piers are common architectural elements.
