Takthok Monastery, Buddhist monastery in Sakti, India

Takthok Monastery stands on a mountainside in Sakti village, about 46 km east of Leh. Its name means "stone roof": rock forms both the walls and, in places, the roof. The main temple has a low rock ceiling blackened by centuries of butter lamps, and the du-khang holds statues of Maitreya, Padmasambhava and Dorje Takposal.

The monastery was founded in the mid-16th century under the reign of Tshewang Namgyal. One of the caves at the site has been associated since the 8th century with Padmasambhava, a central figure in Tibetan Buddhism, who is believed to have meditated there.

The monastery's name, Takthok, means "rock roof" in Tibetan, because rock forms both its walls and, in places, its roof. Its annual Tak Tok Festival (Takthok Tsechu) falls around July–August, moved to summer so pilgrims and tourists can attend; sacred dances are performed on the 9th–10th day of the sixth Tibetan month.

The monastery is located about 46 kilometers east of Leh and is best reached by local transport after arriving in town by plane or bus. Being at high elevation, visitors should allow time for acclimatization and bring warm clothing, especially during winter months.

The monastery keeps the 108-volume Kanjur, the collected teachings of the Buddha, among its holdings. A small cave behind the new temple, consecrated by the 14th Dalai Lama in 1980, is held to be where Padmasambhava lived and meditated for three years.
