Karakorum

Karakorum (Classical Mongolian: ᠬᠠᠷᠠᠬᠣᠷᠣᠮ Qara Qorum, Khalkha Mongolian: Хархорум Kharkhorum) was the capital of the Mongol Empire between 1235 and 1260, and of the Northern Yuan in the 14–15th centuries. It was built as a fortress between 1218 and 1220 at the order of Temujin, Genghis Khan. Its ruins lie in the northwestern corner of the Övörkhangai Province of Mongolia, near today's town of Kharkhorin, and adjacent to the Erdene Zuu monastery. They are part of the upper part of the World Heritage Site Orkhon Valley Cultural Landscape.
