Kenchogsum Lhakhang is also known as Chhoekhor or Bumthang Tsilung lhakhang. It was built in the early 9th century upon the instruction of Guru Rinpoche. Guru Rinpoche instructed the king Thrisong Deutsen of Tibet to build a three-storied temple similar to Samye Monastery of Tibet in Bumthang to serve as center for flourishing dharma, peace, and happiness as Bumthang was believed to be the land of demons in the past. Accordingly, king Thrisrong Deutsen sent his minister Bamir Thrizer to build the lhakhang. The lhakhang was constructed under the supervision of Bamir Thrizer with the support from the communities of Chhoekhor gewog. Guru himself is said to have visited Bumthang to design and perform the auspicious consecration ceremony after the completion. Later, the lhakhang was renovated by tertoen Pema Lingpa in 1479 after it was destroyed by an earthquake. The wall paintings were painted by Kuenga from Lhodrak, Tibet. As prophesized by Guru, tertoen Pema Lingpa revealed two pieces of gold from the statue of Buddha Vairocana and the gold was enough to paint the statues and wall paintings of the lhakhang. The main treasures or relics are the statue of Buddha Vairocana and the three statues of Due Sum Sangay (Buddha of the past, the present, and the future) which is believed to have flown from Kusumphel, Kurtoe. Thus, the presence of the Buddha statue as the main relic gave the name of the lhakhang “Kenchgosum”. Another sacred relic preserved at the lhakhang is the large broken bell (Choedril) which is believed that the religious bell was offered by a Tsomem (mermaid) to Guru Rinpoche while he was performing salang (foundation laying) ceremony to build the lhakhang. To the grievance of the community of Chhoekhor, in February 2010, the lhakhang was razed to the ground by the fire. However, the nangtens were safely retrieved from the fire disaster. The 11th reincarnation of Tertoen Pema Lingpa, His Holiness Lhalung Sungtrul Rinpoche, Jigdrel Kuenzang Pema Dorji has taken up the task of reconstructing the lhakhang and it was completed in 2014. Currently, it is managed by Lhalung Draktshang under Sungtrul Rinpoche.
