[1] The monastery is a huge white building bedecked with prayer flags[2] It is situated on a ridge below the 15,000 foot (4,572 metres) Rangcha peak, at an altitude of 3,500m on the left bank of the Bhaga River, facing the town of Keylong,[3] about 8 km away.

The monastery is believed to have been built in the 12th century and houses a large library of Buddhist literature, including the Kangyur and Tangyur scriptures in the Bhotia or Sherpa language.

There is also a good collection of fine thankas, musical instruments such as lutes, drums, horns, as well as old weapons.

In the first room is a 4-foot (1.23 metres) high silver chaitya or chorten preserving the skull and ashes of Lama Norbu.

[5][6]To the right of it are statues of Padmasambhava and Tara (Devi), and in the back, one of Tagden Shakyashree, guru of Lama Kunga.

[3] The monks spend the summer with their families working their fields, in the winter they return to the monastery.

There is a huge prayer drum in the monastery with the sacred six-syllable mantra, Om mani padme hum, written a million times on strips of paper.

Because the monastery is on the southern bank of the Bhaga River, it gets very little sun, while Keylong on the opposite side gets far more as it is facing south.
