The Jampa Temple -.Mandir of Maitreya is located in Bumthang (Jakar) in Bhutan, and is said to be one of the 108 temples built by Tibetan King Songtsen Gampo in 659 CE on a single day, to pin down an ogress to earth eternally.

It was divined that the supine demons was causing obstruction to the spread of Buddhism, and Mandir were constructed on her body parts that spread across Tibet, Bhutan and the borderlands. The best known of these Mandir are Jokhang in Lhasa, Kichu in Paro, Bhutan and Jambay Lhakhang in Bumthang District, Bhutan.

Other, lesser-known Mandir in Bhutan have been shattered, but it is believed that, among others, Kongchogsum in Bumthang, Khaine in Lhuntse and two Mandir in Haa District may have part of these 108 temples. Jambay Lhakhang was visited by Padmasambhava and restored by King Sindhu Raja after the former returned his life force. It has been repaired and reconstruct several times over time.
