What defines a rib vault?

A rib vault is a significant architectural feature characterized by its use of ribs, or framework, which is typically made of stone or masonry to support the weight of the vault. This structure allows for the creation of a more complex and aesthetically pleasing ceiling while also distributing weight across the ribs, which can be more efficient than traditional vaulting methods. The ribs act as a skeleton, allowing the infill between them to be lighter and often embellished with intricate designs, such as patterns or murals. This innovation was particularly influential in the development of Gothic architecture, where rib vaults enabled the construction of larger and more magnificent cathedrals with soaring ceilings and expansive windows.

The incorrect options describe elements that do not accurately define a rib vault. Covering roofs with tiles pertains to roofing styles rather than the specific function and structure of a rib vault. Designs using wooden beams are applicable to timber framing and are not associated with the stone and masonry focus of rib vault construction. A type of dome structure generally refers to a different architectural form that is rounded and does not incorporate the ribbed framework that characterizes rib vaults.
