Genghis Khan united warring tribes in 1206 and became the leader of the Mongols, creating an empire that eventually stretched from China to Hungary. The famed warrior's tomb, however, has remained a mystery ever since his death in 1227.
According to legend, his burial party killed anyone who saw the procession. The slaves and soldiers who attended the funeral were also killed. Horses then trampled evidence of the burial, and a river was diverted to flow over the grave, which is thought to
lie somewhere near Genghis Khan's birthplace in Khentii Aimag.
Expeditions to locate the tomb have been aborted due to concerns that the excavations would disturb the site and destroy the soul that serves as its protector. In 2004, archaeologists uncovered Genghis Khan's palace, shown here, and they suspect the tomb lies nearby.
