Pit 1, discovered in May 1974, the largest of the three, is in the form of an earth and timber lined rectangle. It is 210 meters (230 yards) from east to west, 62 meters (68 yards) in width and covers a total area of 12,600 square meters (14,350 square yards). The depth fluctuates between 4.5 and 6.5 meters. Five entries were found on each side. Those on the eastern side are the main entrance. Eleven parallel passageways stretch through the vault from east to west. A section of 960 square meters has been fully excavated and marked out as the main attraction of the museum. A three-line vanguard of 204 tunic-infantrymen stands in the front. Immediately behind them are 36 rows of armed soldiers with war chariots at various intervals. A single column of soldiers face north and south flanking the main body of men, while a further column face west as the rear. The functions of the armed soldiers are recognizable by the weapons they carried which include spears, battle-axes, halberds and crossbows.

Visitors enter the pit through the eastern doors and walk towards the south. Track down the southern side of the pit and you can cross a walkway, which affords rear views of the excavated area. Continue down the northern side and you can view the other side of the display. The exit via a small door in the northwest corner leads on to Pit 3.

Typical figures include: An armor clad general, armored soldiers, tunic-infantrymen and war chariots.
