The Do-Drul-Chorten is a Buddhist stupa located in Gangtok, Sikkim, India. Built in 1945 by Trulshik Rinpoche, it is one of the largest stupas in Sikkim, adorned with gold-topped spires and prayer wheels. The stupa is a revered pilgrimage site and a symbol of Buddhist faith and culture in the region.

Since it is one of the three open trading border posts between India and China, Nathu La Pass has played a key role in the Sino-Indian Trade. It has also shortened the distance between the important Buddhist and Hindu pilgrimage sites, thus strengthening the economy and improving border relations with China.
