The figures, dating from approximately the late third century BCE, were discovered in 1974 by local farmers in Lintong District, Xi'an, Shaanxi province. The figures vary in height according to their roles, with the tallest being the generals. The figures include warriors, chariots and horses.
Estimates from 2007 were that the three pits containing the Terracotta Army held more than 8,000 soldiers, 130 chariots with 520 horses and 150 cavalry horses, the majority of which remained buried in the pits nearby Qin Shi Huang's mausoleum. Other terracotta non-military figures were found in other pits, including officials, acrobats, strongmen and musicians.
The Terracotta Army was discovered on 29 March 1974 to the east of Xi'an in Shaanxi province by farmers digging a water well approximately 1.5 kilometres (0.93 mi) east of the Qin Emperor's tomb mound at Mount Li (Lishan),[ a region riddled with underground springs and watercourses. For centuries, occasional reports mentioned pieces of terracotta figures and fragments of the Qin necropolis – roofing tiles, bricks and chunks of masonry. This discovery prompted Chinese archaeologists to investigate, revealing the largest pottery figurine group ever found in China.
A museum complex has since been constructed over the area, with the largest pit enclosed within with a large structure.
