A mysterious underground chamber has been found inside the Chinese imperial tomb guarded by the famous Terracotta Army, Chinese archaeologists say.
The unopened chamber was found at the site near the old imperial capital of Xian using remote sensing technology.
One expert says it may have been built for the soul of the emperor.
More than 2,000 years old, the chamber is buried inside a pyramidal earth mound 51m (170 feet) high on top of Qin’s tomb.
It is situated near the life-size terracotta warriors and has four stair-like walls, says Duan Qingbo, a researcher with the Shaanxi Institute of Archaeology.
