Terracotta Warriors in Xi'an

18. The Pits

The four pits associated with the dig are about 1.5km east of the burial ground and are about 7 meters deep. The outside walls of the tomb complex are as if placed there to protect the tomb from the east, where all the conquered states lay. They are solidly built with rammed earth walls and ground layers as hard as concrete. Pit one, 230 meters long, contains the main army, estimated at 8,000 figures. Pit One has 11 corridors, most of which are over 3 meters wide, and paved with small bricks with a wooden ceiling supported by large beams and posts. This design was also used for the tombs of noblemen and would have resembled palace hallways.

The wooden ceilings were covered with reed mats and layers of clay for waterproofing, and then mounded with more soil making them, when built about 2 to 3 meters higher than ground level. Pit two has cavalry and infantry units as well as war chariots, and is thought to represent a military guard. Pit three is the command post, with high ranking officers and a war chariot. Pit four is empty, seemingly left unfinished by its builders.
