Tamshing Monastery (Tamzhing Lhündrup Monastery) is one of the oldest and most important Nyingma monasteries in Bhutan, founded in 1501 by the treasure-discoverer Pema Lingpa. The main temple houses murals painted under Pema Lingpa's direct supervision — considered among the finest examples of early Bhutanese religious painting still in existence.
The monastery is about 3 km across the valley from Kurjey Lhakhang, and the two are easily visited together. A heavy chain of iron rings inside the temple is believed to have been forged by Pema Lingpa himself; pilgrims carry it as a form of penance and blessing. The annual Tamshing Phala Chhoepa festival, held in the ninth month of the lunar calendar, includes cham (masked dance) performed by the monks.
