Quizplus · Accepted Answer

A cross vault is formed when two barrel vaults intersect at right angles, creating a four-part or groin vault. This is different from a simple barrel vault, which is formed by a series of arches stacked on top of one another. It is also different from a ribbed vault, which has a framework of ribs that create a more complex and intricate pattern.
