The monastery at Darchen, Darchen Gon, is a part of the Drukpa sect. The two-story monastery structure in the center of the town serves as a trading post and shelter for pilgrims. Within the dukhang assembly hall are new and old thangka paintings and some statues, the main image being Sakyamuni. West of the gompa is the Mani Lhakhang that has a large, new mani prayer wheel. This is the site where the original old flagpole (a darchen is a flagpole for prayer flags) of Darchen was located. When beginning their kora pilgrimage around Kailash, many pilgrims often circumambulate the Darchen Gon monastery and the Mani Lhakhang before setting out.
Though Darchen is really not much more than a tent settlement with only a few permanent buildings, it has traditionally been an important center for wool trade.
