Gargaon (Tai-Ahom:Tsé-hung;pronounced [ɡaɹˈɡãʊ]) is a historic city in Assam, India and served as the capital of the Ahom kingdom for many years. It was built by the Ahom king Suklenmung (Gargaiya Roja) in 1540. It lies 13 km east of present-day Sivasagar City, headquarters of the Sivasagar district. The palace structures were made of stone and wood. In 1747 Pramatta Singha, son of Rudra Singha, constructed a brick wall of about 5 km in length surrounding the Gargaon palace and the masonry gate leading to it.
The old palace was destroyed and the present day seven-storied palace was rebuilt around 1752 by Rajeswar Singha (Suremphaa) (1751–1769).
