Kareng Ghar is a palace with three underground floors known as the Talatal Ghar. The upper storeys are known as the Kareng Ghar. This palace was built by king Rudra Singha (1696-1714), and is only 16 km from the present town of Sibsagar. There were two underground tunnels connecting Talatal Ghar and the Gargaon palace with the Dikhow river. These tunnels which served as emergency exits were however later blocked by the East India Company.
