Located in Chummey Valley in Bumthang, Nimalung Dratshang is at an approximately 15 minutes drive from the road that branches off from Chummey Village. The Dratshang was co-founded Dasho Gonpo Dorji and Doring Trulku Jamyang Kunzang, the third mind reincarnation of Terton Jigme Lingpa in the year 1935. During the visit of Doring Tulku to Bhutan, he met Dasho Gonpo Dorji during the funeral ceremonies of Dasho Jamyang, the father-in-law of the Second King Jigme Wangchuck and immediately thought of laying the foundation of a Lhakhang and along with Doring Trulku he decided to open a monastic institution to uphold the school of Buddhism enriched by Kuenkhen Longchen and Jigme Lingpa. This is a two storied temple decorated with murals of the Nyingmapa and Drukpa traditions and its main relic is the statu of Guru Rinpochhe. There are also paintings of Guru Rinpoche and his disciples, the lineage of Terton Pema Lingpa, and several masters affiliated with the monastery.
Nimalung tshechhu is one of the most important festivals held at the Lhakhang. During the festival a nine meters high and twelve meters wide Guru Rinpoche Thongdrol (large Scroll Painting) is unfurled. The Thongdrol was donated by Lopen Pemala was consecrated in June 1994 in the presence of a large crowd of villagers by Lhalung Thuksey Rinpoche, the mind reincarnation of Pema Lingpa. A series of mask dances are also performed during the festival.
