The Terra Cotta Warriors and Horses are the most significant archeological excavations of the 20th century. Work is ongoing at this site, which is around 1.5 kilometers east of Emperor Qin Shi Huang's Mausoleum, Lintong County, Shaanxi province. It is a sight not to be missed by any visitor to China. Upon ascending the throne at the age of 13 (in 246 BC), Qin Shi Huang, later the first Emperor of all China, had work begun on his mausoleum. It took 11 years to finish. It is speculated that many buried treasures and sacrificial objects had accompanied the emperor in his after life. A group of peasants uncovered some pottery while digging for a well nearby the royal tomb in 1974. It caught the attention of archeologists immediately. They came to Xian in droves to study and to extend the digs. They had established beyond doubt that these artifacts were associated with the Qin Dynasty (211 --206 BC). Life size terracotta figures of warriors and horses arranged in battle formations are the star features at the museum. They are replicas of what the imperial guard should look like in those days of pomp and vigor. The museum covers an area of 16,300 square meters, divided into three sections: No. 1 Pit, No. 2 Pit, and No. 3 Pit respectively. Altogether over 7,000 pottery soldiers, horses, chariots, and even weapons have been unearthed from these pits. Most of them have been restored to their former grandeur. The Terracotta Warriors and Horses is a sensational archeological find of all times. It has put Xian on the map for tourists. It was listed by UNESCO in 1987 as one of the world cultural heritages.
