Khoymorsky datsan, Buddhist monastery in Arshan, Buryatia, Russia

Khoymorsky datsan is a Buddhist monastery in Arshan, Tunkinsky District, Buryatia, founded in 1917 by Agvan Dorzhiev at the foot of Mount Mundarga. The complex, rebuilt in the early 1990s on the "Holy Glade" site, includes two stupas and the former personal house of Dorzhiev, which now serves as the main temple.

In 1917, at the request of monks and laypeople of the Tunka Valley who wanted to move the Kyrensky datsan, the Khambo Lama Agvan Dorzhiev chose a site at the foot of Mount Mundarga in the Tunka Goltsy. The datsan was closed in 1936 and most of its clergy were repressed in the 1930s; its property went to kolkhozes and its main building to the kolkhoz of Galbay. Reopened in 1991 on the "Holy Glade" near Arshan, it was consecrated by Danzan-Khaibzun Samaev and named Bodhidharma.

The monastery serves as a living center of Tibetan Buddhist practice where visitors can observe daily rituals and ceremonies. The community gathers here for prayer, study, and celebrations that reflect the spiritual traditions of the region.

The datsan stands on the "Holy Glade" site near the village of Arshan, in the Tunkinsky District of Buryatia, at the foot of Mount Mundarga in the Tunka Goltsy range. The complex is reached from Arshan, where the former house of Agvan Dorzhiev, moved here from Nomto-Khobok, serves as the main temple. Two stupas stand on the grounds.

Before 1917, at Agvan Dorzhiev's insistence, the datsan's property was held as collective ownership by a community of monks numbering up to 200, who ran their own farm and were taught Russian alongside the Buddhist curriculum. The current clergy keeps these customs where possible.
