Isn't that the top stone in an arched or rounded doorway?  I remember that from a Ken Follet novel.

I knew this one but thought a graphic might help explain it. NOT just "a stone" but the single stone that takes all the pressure where the arch meets.

I remember this from a history class long ago, it was an important inovation that allowed much larger buildings and openings with an ARCH, and at the top of the arch is the Keystone.

A keystone is the wedge-shaped stone piece at the apex of a masonry arch, the generally round one at the apex of a vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight. In both arches and vaults, keystones are often enlarged beyond the structural requirements, and often decorated in some way. Keystones are often placed in the centre of the flat top of openings such as doors and windows, essentially for decorative effect.
