The Do-drul Chorten or Stupa was built by the Venerable Trullshi Rimpoche, head of the Nyingma order of Tibetan Buddhism, in 1945.

Inside the Stupa, there are complete mandala set of Dorjee Phurba (Vajra Kilaya), a set of KangOyur relics (Holy Books), complete 'Zung' (mantras) and other religious objects. Around the Chorten, which is one of the most important Stupas in Sikkim, are 108 Mani Lhakor (Prayer wheels).

These Prayer Wheels are turned by the devout Buddhist while chanting 'Hail to the Jewel in the Lotus', to invoke the Bodhisattva. The Chorten is surrounded by Chorten Lakahang and Guru Lakhang, where there are two huge statues of Guru Rimpoche (Guru Padamsambhava).
