KharKhorum (Karkorum) was the capital of the Mongolian Empire between 1235 and 1260, and the Northern Yuan in the 14–15th centuries. Erdene Zuu monastery stands near Karakorum. Various construction materials were taken from the ruin to build this monastery.
Dening Hall built in 1270 during the Mongol Yuan Dynasty closely resembles the lost palace architecture of Mongol Dadu (Beijing) and Karakorum.
The actual location of Karakorum was long unclear. First hints that Karakorum was located at Erdene Zuu were already known in the 18th century, but until the 20th century there was a dispute whether or not the ruins of Karabalgasun, or Ordu-Baliq, were in fact those of Karakorum. In 1889, the site was conclusively identified as the former Mongol capital by Nikolai Yadrintsev, who discovered examples of the Orkhon script during the same expedition. Yadrintsev’s conclusions were confirmed by Wilhelm Radloff. Central Tours
