Built in 659 AD by the Tibetan King Songtsen Gampo, Jambay Lhakhang is among the oldest surviving Buddhist sanctuaries in the Himalayas. Established as one of 108 border-taming temples constructed overnight across the Tibetan plateau to pin down an immense mythical demoness, the sanctuary marks her left knee. The inner sanctum preserves an ancient central statue of Jowo Jampa (Maitreya, the Future Buddha), flanked by intricate, centuries-old murals depicting the life of the Buddha and the lineage of great masters.
Unlike larger fortress-monasteries, Jambay Lhakhang retains an intimate, ancient village sanctuary atmosphere. The stone courtyard is paved with smoothed river slate, where local elders from surrounding farmsteads gather daily to circumambulate the temple walls and spin the perimeter prayer wheels. Every autumn, the temple grounds host the renowned Jambay Lhakhang Drup festival, celebrated for its sacred midnight fire dances (Mewang) and traditional cham dances performed to bless the harvest and ward off misfortune.
