Menri, the main Bon monastery located in Namling county in central Tibet, was founded in 1404 or 1405 by Nyamme Sherab Gyeltsen. At one time it housed 350 monks, four colleges, a school of dialectics, and an assembly hall. It was largely destroyed during the cultural revolution, and although some restoration has occured, the site still has extensive ruins and only a small cohort of monks.
