Situated on the banks of the Orkhon rive, Kharakhorum is the most important cultural and religious site in Mongolia. It was chosen in 1220 as the site of the capital of the great Mongolian Empire by Genghis Khan and later moved by his grandson, Kublai Khan. Sadly today little remains of what was once a great city but some religious sites such as the grand site of Erdene Zuu which was Mongolia's largest and grandest monastery.
