Lhakhang Karpo was established in the 7th century by Tibetan king Songtsen Gempo in his mission to build 108 monasteries in one day. He built Lhakhang Karpo and Lhakhang Nagpo in the Haa Valley. According to a legend, a black and white pigeon were released to select sites to build the temples.
These two temples stand as the guardian sentinels keeping watch at the south entrance of the valley. The white pigeon landed on the foothills of the three towering mountains worshipped as Rigsum Gonpo and is where the Lhakhang stands today.
The temple was named Karpo (white) as it was built on the site where the white pigeon landed.
Located in Dumchoe village, the monastery was established in the 7th century by King Songtsen Gampo in his mission to build 108 monasteries in one day. It is situated towards the north of Lhakhang Karpo. Legend has it that King Songtsen Gampo released a black and a white pigeon to select sites to build the temples. The black pigeon landed a little north of the white pigeon, indicating the preordained site of the present Lhakhang Nagpo. The temple was named Nagpo (black) as it was built on the site where the black pigeon landed. Built on a lake; an opening in the floor of the temple serves as the channel to the underground lake. Lhakhang Nagpo serves as the seat for the guardian deity Da Do Chen.
