Erdene Zuu Monastery

The Erdene Zuu monastery is probably the most ancient Buddhist monastery in Mongolia. It is in Övörkhangai Province, near the town of Kharkhorin and adjacent to the ancient city of Karakorum. It is part of the World Heritage Site entitled Orkhon Valley Cultural Landscape.
The monastery was built in 1585 by Abtai Sain Khan, upon the introduction of Buddhism into Mongolia as the state religion. Stones from the ruins of Karakorum were used in construction. It is surrounded by a wall featuring 108 stupas, 108 being a sacred number in Buddhism, and the number of beads in a Buddhist rosary.
The monastery was damaged by warfare in the 1680s, but was rebuilt in
the 18th century and by 1872 had a full 62 temples inside.
