into Tibet from Assam. Architecture and ruins The entire area of Sadiya was a well developed city in the medieval times. The ruins like Bhismaknagar, Rukmininagar, Tamreswari temple, Shiva temple, Pratima garh, Bura-buri temple built during the Chutia period. Tamreswari (Kechai-Khati) Temple This was the most notable among the temples built by Chutia kings. The temple was dedicated to Kechaikhati, a primordial female tribal deity commonly found among different Bodo-Kachari groups. As per the Kalika Purana, the main temple was octagonal in shape surrounded by eight dwarapals in eight directions. When the British visited the temple complex, the main temples has disappeared and only a small square structure remained. The wall and doors of the temple were well designed with beautiful works. There were two giant elephant sculptures with silver tusks at the main door of the complex. The walls were made without any mortar and instead used iron dowels and brackets.

According to S.F. Hannay, the temple complex was as near as possible square with the doorway to the west. There was a substantial brick wall, about 4.5 feet thick rising to the height of 8 feet, on the foundation of rudely cut blocks of sandstone.
