Old Ikh Khüree, once the city was set up as a permanent capital, had a number of palaces and noble residences in an area called "Öndgiin sürgiin nutag". The Jebtsundamba Khutughtu, who was later crowned Bogd Khan, had four main imperial residences, which were located between the Middle ("Dund gol") and Tuul rivers. The summer palace was called "Erdmiin dalai buyan chuulgan süm" or "Bogd khaanii serüün ord". Other palaces were the White palace ("Tsagaan süm" or "Gьngaa dejidlin"), and the Pandelin palace (also called "Naro Kha Chod süm"), which was situated in the left bank of Tuul River. Some of the palaces were also used for religious purposes.
