In the area of ancient Karakorum,
four granite tortoises each
of which once bore an inscribed
stela on its back can be found.
Their age and origin are disputed,
but one of them seems to guard
the hillock covering the remains
of the palace that was built by
Ugedei, son of Genghis Khan.
A team of Mongolian and
German archaeologists are now
excavating part of the palace.
