DO Drul Chorten is one of the top tourist attraction in Gangtok.It is believed that this entire place was once haunted by evil spirits and many people who wandered around this place became victims and died. Later a very respected and celebrated lama of Tibet Trulshig Rinpoche who followed Nyingma Order of Buddhism came to this place for hermitage. He built this stupa in 1946 to drive away the spirits.
The stupa is surrounded by 108 prayer wheels all of which have mantras inscribed on them in Tibetan. If you rotate the prayer wheels, do it in clockwise direction. Inside the Chorten Stupa are Kanjur holy books, relics, complete mantras and several other religious objects. The stupa is surrounded by Chorten Lakahang and Guru Lakhang, where two statues of Guru Rinponche are worshipped. There is a butter lamp room located beside the chorten, where you can offer donation and light a butterlamp.
