Nangkhar Dordhen Chorten (Bodhgaya in Bhutan) is in Nangkhar village under Toedtsho Gewog, Trashi Yangtse. It was founded by the renowned yogic master, Druptho Thogmey Dorji, who was a profound Buddhist master and a practitioner. He visited this region some hundred years back and constructed two sacred stupas to sanctify the region. He is also the founder of Nangkhar Tashi Choling Lhakhang (a.k.a Nangkhar Gonpa) in Toedtsho, Trashi Yangtse and Khabti Gonpa in Bikhar, Trashigang. Nangkhar Gonpa was in the state of ruined until later restored by Lama Drakpa.
