Sera Tekchen Ling is one of the three main Geluk monasteries in Lhasa. It was founded in 1419 by Jamchen Choje Shakya Yeshe, a disciple of Tsongkhapa. Three monastic colleges survive: Sera Me, Sera Je, and the Ngakpa Dratsang. Above the monastery are a number of important hermitages established by Tsongkhapa and other Geluk masters. These include Sera Utse, Pabongkha, and Purbuchok.
