===Mobile monastery===Founded in 1639 as a yurt monastery, Ulan Bator, then Örgöö (palace-yurt), was first located at Lake Shireet Tsagaan nuur (75 km directly east of the imperial capital Karakorum) in what is now Burd sum, Övörkhangai, around south-west from the present site of Ulan Bator, and was intended by the Mongol nobles to be the seat of the first Jebtsundamba Khutughtu, Zanabazar, son of Tusheet Khan Gombodorj (1597-1655).
Nukhtiin Am na jugu Ulan Batorja, kjer je bil Zanabazar (1635-1723) posvečen in je meditiral pod drevesom, se je imenoval Janchivsembe, senca, ki je bila izbrana lokacija za postavitev samostana Gandan leta 1838.
