Bhismaknagar Fort

Bhismaknagar Fort is an ancient brick fort ruin located about 30 km from Roing in Lower Dibang Valley, Arunachal Pradesh. Believed to date to the 8th century and associated with the Chutiya kingdom, it is one of the oldest archaeological sites in the state. The fort features extensive brick ramparts, gateways and central complex remains set amid forested hills, and is protected by the Archaeological Survey of India.

Visitors can expect extensive ruins of a large fortified settlement spread over a hillock surrounded by dense forest. Remains include high brick walls, bastions, gateways, and foundations of the central complex and residential areas. The site is largely open-air with uneven ground, scattered brick structures, and interpretive signage. The surroundings are quiet and natural, offering views of the valley and opportunities for photography and leisurely exploration of the archaeological remains.

Bhismaknagar Fort is attributed to the Chutiya kingdom and dated to around the 8th century CE based on archaeological excavations. Excavations by the Archaeological Survey of India revealed extensive brick fortifications, pottery, terracotta and other artifacts indicating an early medieval fortified urban settlement. Local legend associates the site with King Bhismaka from the Mahabharata and his daughter Rukmini.

The fort holds cultural significance due to its association with the legend of King Bhismaka and Rukmini, and as an important heritage symbol of the Idu Mishmi and Chutiya cultural history of Arunachal Pradesh. It is a protected archaeological site representing early brick architecture in Northeast India.
