Additionally, the groin cross vault’s shape provides natural light from the sides and its angles create interesting geometric patterns. Groin cross vaults also benefit from their unique shape, which creates more area for roofing materials to be used, which helps to further support and protect a building. Groin cross vaults require just two parallel walls, while barrel vaults need at least four walls.

The main advantages of the groin cross vault over the barrel vault are that they provide more strength and stability, can span larger distances, and require less support to construct. What are the main advantages of the groin cross vault over the barrel vault? Groin vaults also require more materials to construct than a barrel vault, and usually require four ribs or arches to support them which can make them more expensive.

In comparison to the curved shape of a barrel vault, a groin vault has a more angular visual appearance due to the intersections of four arches at the same point. This design creates square or rectangular openings in the middle of the vault, which is why it is sometimes referred to as a “cross vault”. It is typically curved or rounded in its structure, resembling a tunnel that curves through a structure.Ī groin vault, on the other hand, is a type of vault consisting of two barrel vaults intersecting each other at right angles.

A barrel vault is a continuous arch-shaped structure that forms a ceiling or roof along the length of a building.
