Drigung Thil Monastery (Wylie: 'bri gung mthil 'og min byang chub gling) is a monastery in Maizhokunggar County, Lhasa, Tibet founded in 1179. Traditionally it has been the main seat of the Drikung Kagyu tradition of Tibetan Buddhism. In its early years the monastery played an important role in both religion and politics, but it was destroyed in 1290 by Mongol troops under the direction of a rival sect. The monastery was rebuilt and regained some of its former strength, but was primarily a center of meditative studies. The monastery was destroyed after 1959, but has since been partly rebuilt. As of 2015 there were about 250 resident monks.
