Kyichu and Jambay Lhakhangs are one of the oldest and most sacred temples in Bhutan built in the 659 AD in the seventh century by Tibetan King Songtsen Gyampo. Jambay Lhakhang is located in Bumthang and Kyichu Lhakhang in Paro. Both the Lhakhangs are two of the 108 Lhakhangs that King Songsten Gyampo built in a single day. According to legend, the King built all 108 Lhakhangs over the body of a giant demoness to pin her on the earth forever. The Lhakhangs were built on her body parts spanning Bhutan, Tibet and border areas. The Jambay Lhakhang Drup is one of the most unique and different festivals of Bhutan. The most popular and legendary Tercham (Dance of Treasure) is performed during the festival. The dancers perform the dance completely naked wearing only a mask around a bonfire. It is believed that witnessing this dance blesses infertile men and women with children. This dance is performed only at night. The Kyichu Lhakhang houses some of the oldest relics and an original 7th century statue of Buddha Sakyamuni. The wooden floor of the main Lhakhang is inlaid with turquoise and other precious gems and stones.
