Rabdentse Ruins are the ruins of the palace which was destroyed by the Nepalese Army. The ruins of the palace as well as the chortens (the place where the prayers were done in the palace) remain as a reminiscence of the former kingdom of Sikkim.
Rabdentse was the second capital of Sikkim, the first capital being Yuksom. The Rabdentse Ruins are a part of Buddhist pilgrimage circuit which consists of many monasteries starting from the Yuksom, which is the Dubdi Monastery.
The ruins of Rabdentse are divided into two wings – the northern wing and the southern wing. The northern wing is where the royal family resided. There is an open quadrangle where the ruins of Dab Lhagang, the place where the royal family used to offer prayers, remain.
The palace is preserved by the Archaeological Survey of India and is also considered to be a monument of national importance in India.
