Solution to Last Week's Puzzler
Architecture Puzzler #483

Question

What is a groined vault?

Answer

A common form in Gothic cathedral roofs, a groined vault consists of two intersecting cylindrical vaults at right angles to each other. This roof form is supported by the arches of the two intersecting vaults. The curved diagonal folds at the intersecting joints of the vault are called "groins."
