Talatal Ghar: Palace with underground storeys and secret tunnels
Talatal Ghar is a seven-story palace with tunnels and mazes in Rangpur, Assam. Built using a mixture of sticky rice and swan eggs, it is said to conceal the Rajbharal, the royal treasury of the Ahom dynasty, which ruled Assam for 600 years. Local stories also tell of people getting lost in the maze-like underground chambers.
