Pemayangtse is situated in West Sikkim at Gyalshing (140 Kms. from Gangtok) and commands an impressive view of Mt. Kanchendzonga. It was originally a small Lhekhang build by Lhatsun Chenpo in the 17th century. Later during the rule of the third Chogyal Chakdor Namgyal, Lhatsun Chenpo's third reincarnate jigme Pawo extended it and rebuild the structure. This monastery belongs to the Nyigma order and all other Nyigma order monasteries in Sikkim are subordinate to it. The monks of Pemayangtse are usually from the leading Bhutia families in Sikkim. There are 108 monks in this monastery.
The monastery houses numerous religious idols and other objects of worship, most of which are precious because of their antiquity. On the top floor of the monastery there is a wooden sculpture depicting the Maha Gurus Heavenly Palace "Sanghthokpalri". This master piece was completed by the late Dungzin Rimpoche, who took five years to craft it single handed. The main festival of the monastery is on the 28th & 29th day of the 12th month of the Tibetan calender, normally corressponding to the month of february. During these two days religious dances are performed and pilgrims come from all over Sikkim to watch them.
