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 .
Ploughshare vault – A Rib vault where the wall ribs spring from a higher position than those of the diagonal ribs. Quadripartite vault – A Rib vault where the bay is divided by diagonal and transverse ribs into four cells or webs. Rampant vault – A Barrel vault where one springing in point is higher than the opposite springing point.
In later buildings employing ribbed vaultings, groin vaults are most frequently used for the less visible and smaller vaults, particularly in crypts and aisles. A groin vault is almost always square in plan and is constructed of two barrel vaults intersecting at right angles. Unlike a ribbed vault, the entire arch is a structural member.

In architecture, a vault (French voûte, from Italian volta) is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof.
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.
A pattern of three stages—vault, arcade and clerestory—was established in the 11th century. [9] Masonry vaults were preferred for larger churches, and were initially barrel or groin vaults, often with arches spanning the nave between the vaults. Vaulted bays are square. [9] The earliest ribbed high vault in France is at Saint-Etienne, Caen ...
A common association of vaulting in cathedrals of the Middle Ages involves a nave of barrel vault design with transepts of groined vaulting. [8] Rib vaults resemble groin vaults but introduce structural ribs running along the angles which carry much of the weight, making possible much greater variations of proportion.
The rib vault quickly replaced the Romanesque barrel vault in the construction of cathedrals, palaces, and other large structures. In a barrel vault, the round arch over the nave pressed down directly onto the walls, which had to be very thick, with few windows, to support the weight. In the rib vault, the thin stone ribs of the pointed arches ...
