Upon ascending the throne at the age of 13 (in 246 BC), Qin Shi Huang, later the first Emperor of all China, had begun to work for 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 archaeologists 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).

The State Council authorized to build a museum on site in 1975. When completed, people from far and near came to visit. Xian and the Museum of Qin Terra Cotta Warriors and Horses have become landmarks on all travelers' itinerary.

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. They were tagged in the order of their discoveries. No. 1 Pit is the largest, first opened to the public on China's National Day, 1979. There are columns of soldiers at the front, followed by war chariots at the back.

Terra Cotta Warriors and Horses Museum, Xian, China No. 2 Pit, found in 1976, is 20 meters northeast of No. 1 Pit. It contained over a thousand warriors and 90 chariots of wood. It was unveiled to the public in 1994. Archaeologists came upon No. 3 Pit also in 1976, 25 meters northwest of No. 1 Pit. It looked like to be the command center of the armed forces. It went on display in 1989, with 68 warriors, a war chariot and four horses.

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.
