Large number of Buddhist monasteries and temples were built throughout Mongolian territory between 1600 and 1800s. In the eastern Mongolia, in 1779 there was an establishment of one important and powerful monastery. At the beginning, the monastery’s name was “Baldandashgomlin” as Tibetan.  During the prosperity of Buddhism in Mongolia, this monastery played the main role to prepare religious staff, especially high educated lamas knowing Tibetan, Indian and Sanskrit and science of astrology. Philosophical creatures of Buddhism, poetries were translated from mentioned languages into Mongolian.

It marked out for monastery’s capacity and how big it was, nearly 1500 inhabitation of Buddhist lamas and 5-7 religious schools and faculties like “Choir”, “Djud”, “Mamba”, “Duinkhor” and etc. Noted handicraftsmen and merchants lived there, except only lamas. Additionally, more than 500 monasteries of the 700 Mongolian monasteries had their own local variations of the ceremony. “Zahra” and “Duinkhor” tsam dance - the most popular religious mask dance were played and the biggest celebration of Buddhism “Maidar ergekh” was held in the Choir monastery as well.

The monastery’s leaders were high mental potential Lamas. The 5th leader was Lama Gonchigdambil, once his camp was on a fire and burnt to the ground but amazingly only single thing was found from camp ashes without any damage. That was the fifth leader’s portrait drawn by him. The portrait is being kept in the Gandan Monastery, present Mongolian biggest Buddhist center. Between 1937 and 1939, religious persecution became common and a political opposition began to form. Almost all monasteries and temples were destroyed. In 1938, this black wind knocked down and set the monastery on fire. Now only the ruin of monastery exists.  The Ruin of Choir Monastery was taken into Mongolian State protection in 1993.
