What is the definition of a groin vault?

Answer:

A groin vault is a structure that has two barrel vaults of the same diameter which cross or intersect one another.

A groin vault is a type of vault formed by the intersection at right angles of two barrel (tunnel) vaults. The arches of groin vaults are often described as meeting at a point, resembling a V shape. This architectural element is commonly used in ceilings and roofs to distribute weight and provide support.

The name "groin vault" comes from the way the two vaults intersect or cross each other, creating a distinct architectural feature that is both functional and aesthetically pleasing. The design of a groin vault allows for the transfer of loads to the corners, making it a stable and durable structure.

Overall, a groin vault is a unique architectural element that adds character and strength to buildings, creating visually striking spaces with a sense of grandeur and elegance.
