Rang Ghar (pronounced 'Rong' Ghar by authentic Assamese) is one of the finest pieces of Ahom architecture. The front view with all the garden and landscaping would have you believe that you might be looking at the Taj instead.

Built in the 18th century, this building served as the amphitheater for Ahom royalty, from where they could watch sporting events such as bull fights, buffalo fights, cock fights and wrestling, that were conducted in the adjoining field named Rupahi Pathar.

It is a two storey building with an inverted-boat-shaped roofing. The native building material comprising of thin bricks, rice paste, eggs, fish, lime and pulses, used in the constuction of Rang Ghar, ensured that the interiors were kept significantly cool.
