The Tsuklakhang Royal Chapel is the most sacred Buddhist site in Gangtok, the former palace monastery of the Chogyal dynasty that ruled Sikkim until 1975. The building is an impressive example of traditional Sikkimese architecture, its interior decorated with exquisite thangkas, murals, and statues accumulated over generations of royal patronage.
The chapel is opened to the public during major festivals, most notably Losar (Tibetan New Year) and Dasain, when it fills with monks and devotees. At other times access may be restricted — it is worth asking locally. The palace grounds command fine views over the town and valley below.
