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.
When two semicircular barrel vaults of the same diameter cross one another their intersection (a true ellipse) is known as a groin vault, down which the thrust of the vault is carried to the cross walls; if a series of two or more barrel vaults intersect one another, the weight is carried on to the piers at their intersection and the thrust is ...
Annular vault – A Barrel vault springing from two concentric walls. Barrel vault – An architecture tunnel vault or barrel vault is a semicircular arch extended in depth: a continuous series of arches, one behind the other. The simplest form of an architecture vault, consisting of a continuous surface of semicircular or pointed sections.
Only few of the older hall churches have groined vaults, though crypts had been constructed as halls of groined cross vaults since long ago. In some single Angevine buildings, ribs were used for barrel vaults and upon chapels and choirs with ceilings consisting of a barrel and half a dome, resulting in early kinds of net-vaulting.
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. Groin vaults are frequently separated by transverse arched ribs of low profile as at Speyer and Santiago de Compostela.
The domed trellis vault of Parish of Our Lady of the Consolation in Seville, Spain by Hernán Ruiz is dated to the 1560s. [62] Barrel vaults and domes are introduced into the gothic church style of the island of Sardinia in the second half of the 16th century by engineers working for the Spanish Crown and the Society of Jesus.

Bartizan An overhanging, wall-mounted turret projecting from the walls, usually at the corners, of medieval fortifications or churches. Basement
The barrel vaults supporting these two new domes were also extended out over the side aisles, creating cross-domed units. [188] By bracing the dome with broad arches on all four sides, the cross-domed unit provided a more secure structural system. [184]
