Sho Monastery, belonging to the Martsang Kagyu tradition, located in Kham, was founded in 1167 by Marpa Sherab Yeshe. At one point it is said that 10,000 monks resided there. While many area monasteries were being converted to Geluk, the Marstangpas fled to Pelyul, a major Nyingma Monastery, where their tradition was absorbed. A Drukpa Kagyu monastery took its place for a time, housing monks and nuns into the 1940s. It was destroyed during the Cultural Revolution and at present the site is largely in ruins.
