QIN SHI HUANG’S TOMB
Currently the tomb remains unexcavated, archaeologists choosing to wait until they can safely do so without damaging any of the contents. Non-invasive studies that locate magnetic anomalies have been able to discern a tomb chamber some 80 metres in length, 50 metres in width and 15 metres high. Ancient Chinese historian Sima Qian describes an underground palace with rivers of mercury.
