The Tamchinsky datsan (Buriat: Тамчын дасан, Tamchyn Dasan), also called the Tamchinskii datsan or Gusinoozyorsk Datsan, is a Buddhist monastery founded in the mid-18th century in the village of Gusinoye Ozero, located on the south-western shore of Lake Gusinoye, Buryat Republic, Russia.
In 1809, the monastery became "the center of Buddhism in eastern Siberia".[1]
Lama Dashi-Dorzho Itigilov received his medical training here.[2]
The temple, which was ransacked in the 1930s, was being restored as of 2013 "as part of the revival of the Buddhist cultural and spiritual legacy in Buriatiia."[1]
Ceremonies at the temple were filmed in the Pudovkin's fictional drama Storm Over Asia (1928 film).
