This vault opened to visitors in 1979. It measures about 210 meters long and 62 meters wide and the bottom of the pit varies from 4.5 meters to 6.5 meters below ground level. Ten earthen walls were built at intervals of 2.5 meters, forming 9 circling corridors. About 6000 terracotta figures of soldiersand horses face east in a rectangular array, each one either armed long spear, dragger or halberd. The vanguard appears to be three rows of infantry who stand at the easternmost end of the army. Close behind is the main force of armored soldiers holding weapons, accompanied by 38 horse-driven chariots.
On the southern, northern and western side there stand one row of figures serving as the army's defense wing. Standing in front of such grand ancient army array, one would feel the footstep of the marching soldiers.
