Dro-dul Chorten (Stupa) The Dro-Dul Chorten or Stupa is one of the most important Stupas of Sikkim, was built in 1945 by the Venerable Trullshi Rimpoche, head of the Nyingma order of Tibetan Buddhism. Inside the Chorten there are complete set of Dorjee Phurba ( Vajra Kilaya), a set of Kang oyur  ( Holi Book) relics, complete "Zung" ( Mantras) and other religious objects. Around the chorten, there 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 Boddhisattava. The chorten is surrounded by Chorten Lhakhang and Guru Lhakhang, where there are two huge statues of Guru Rimpoche (Guru Padsambhava).
