Mausoleum of Qin Emperor

Entry into the tomb of Chinese Emporer Qin Shi Huang Di is forbidden. Although his Terracotta Warriors have been excavated, no one has ever entered his tomb. He was the most tyrannical and violent leader in Chinese history, so there is a lot of superstition about evil spirits around his tomb. Ancient historians wrote that the tomb contains rivers of mercury mechanically operated to flow like real rivers. Modern tests have reported mercury levels in the soil over 100 times what occurs naturally, so it could prove dangerous to open it. The Chinese government does not allow the tomb to be opened and restricts people from access to the land surrounding the tomb.
