Jambay Lhakhang, Tibetan Buddhist monastery in Jakar, Bhutan.

Jambay Lhakhang is a Buddhist lhakhang in Bumthang, about one kilometre before Kurjey Lhakhang on the road to Jakar. It is one of the 108 temples King Songtsen Gampo ordered built in a single day in 659 CE, and it stands on the left knee of the supine ogress. The temple was visited by Padmasambhava and later restored by King Sindhu Raja.

Construction of this monastery dates to 659 CE when King Songtsen Gampo built it as part of a larger building program. It was one of approximately 108 temples created across the Himalayan region during this period.

Jambay Lhakhang Drup is held over five days, from the 15th to the 19th of the 9th Bhutanese month, in the monastery courtyard. It marks the founding of the lhakhang and honours Guru Rinpoche, who consecrated it. The festival is known for its masked dances, including the Tercham performed at night.

The monastery is accessible via road connections from Thimphu or Paro, and guided tours allow visitors to explore the grounds thoroughly. Planning ahead is helpful, especially if you want to attend festival events.

Jambay Lhakhang is said to pin down the left knee of the supine ogress that blocked the spread of Buddhism, one of 108 temples Songtsen Gampo raised in a single day in 659 CE. Of the twelve built to exact calculations, it is one of only two in Bhutan, with Kichu Lhakhang in Paro.
