The Rang Ghar is a two-storied building which once served as the royal sports-pavilion where Ahom kings and nobles were spectators at games like buffalo fights and other sports at Rupahi Pathar (pathar meaning "field" in Assamese) - particularly during the Rongali Bihu festival in the Ahom capital of Rangpur.
It is 3 km away from the center of the Sivasagar Town. Situated by the side of the Assam Trunk Road, it lies to the northeast of the Rangpur Palace, a seven-storied royal complex comprising the Talatal Ghar and the Kareng Ghar.
