A 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; cf. ribbed vault. Sometimes the arches of groin vaults are pointed instead of round (see the image of the Gårdslösa Church below). In comparison with a barrel vault, a groin vault provides good economies of material and labour. 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.

Groin vault construction was first exploited by the Romans, but then fell into relative obscurity in Europe until the resurgence of quality stone building brought about by Carolingian and Romanesque architecture. It reached its ultimate expression in the Gothic architecture of the Middle Ages. Difficult to construct neatly because of the geometry of the cross groins (usually elliptical in cross section), the groin vault required great skill in cutting stone to form a neat arris. This difficulty, in addition to the formwork required to create such constructions, led to the rib vault superseding the groin vault as the preferred solution for enclosing space in Gothic architecture.[1]

The construction method was particularly common on the basement level, such as at Myres Castle in Scotland, or at the ground floor level for the storerooms as at Muchalls Castle in Scotland.[2]

While the barrel vault was more common than the groin vault in very early architecture, including Roman and even earlier civilizations, the Romans developed the groin vault widely for applications in a variety of structures, some with significant span widths. However, it was not until the Middle Ages, when the aspirations of church building reached its zenith, that the groin vault was pursued aggressively for its ability to create strength, without massive buttress formations; in addition, it provided the church architects a remedy for the dim illumination inherent in the barrel vault design, since the barrel vault had to minimise fenestration to retain adequate strength.

20th-century structural engineers have studied the static stress forces of the groin vault design and validated the Romans' foresight in an efficient design to accomplish the multiple goals of: minimum materials use, wide span of construction, ability to achieve lateral illumination and avoidance of lateral stresses. A seminal modern design is the largest European train station, Hauptbahnhof in Berlin, which features an entrance building with a glass spanned groin vault design.[3]

Comparison with other vault designs

The construction of a groin vault can be understood most simply by visualising two barrel vault sections at right angles merging to form a squarish unit. The resulting four ribs convey the stress loading to the four corners, or piers.[4] The more complex groin vault is intrinsically a stronger design compared to the barrel vault, since the barrel vault structure must rest on long walls creating less stable lateral stress, whereas the groin vault design can direct stresses almost purely vertically on the piers.[5] A common association of vaulting in cathedrals of the Middle Ages involves a nave of barrel vault design with transepts of groined vaulting.[6] The fan vault is similar to the groin vault in theory, but has a much more elaborate splaying of multiple ribs emanating from each springer, either decoratively or structurally.
