Built in the 12th century, this monastery has an old library, which is known as the largest Buddhist library in the country. The library has Kangyur and Tangyur scriptures written in the Bhotia or Sherpa language. The monastery has a vast collection of Thanka paintings, musical instruments such as lutes, drums, horns, and some old weapons. The gompa was renovated in the year 1912 by Lama Norbu Rinpoche.
