Perched on a small hill that rises from the stunning Phobjikha valley is the small village of Gangtey, famous for having the largest Nyingmapa monastery in Bhutan. Gangtey monastery is in fact the only Nyingmapa monastery on the western side of the Black Mountains and is surrounded by a large village inhabited mainly by the families of the 140 gomchens who look after it. The village was founded by Pema Trinley; the grandson of Pema Lingpa, the famous saint of Bhutan; and the monastery was established in 1613. The second Tulku, Tenzin Legpa Dondrup (1645 to 1726), enhanced the size of Gangtey and rebuilt the monastery in the form of a Dzong. To this day, the religious Nyingmapa school of Buddhism still teaches the lessons of Pema Lingpa.
