Assyrian Building Voussoirs

View looking down on the top of the arches of several of the buildings that date to the Assyrian Period (7th century B.C.).  The mud–brick voussoirs of the very early mud–brick vaults are clearly visible!   See below.

The Encyclopedia of Archaeological Excavations in the Holy Land states that this ". . . is one of the most remarkable structures ever found in Israel because it preserves vaulted mud-brick ceilings that were erected with keystone-shaped bricks, or voussoirs, marking the earliest known use of voussoirs in world architecture" (p. 670).

Unfortunately the protective roof was ripped off, by winds, and all of these structures have been destroyed as they have been exposed to the rains.
