Recent excavations of ruins of Hindu temples, such as the 14th-century Malinithan at the foot of the Siang hills in West Siang, indicate they were built during the Sutia reign. Another notable heritage site, Bhismaknagar (built in the 8th century), has led to suggestions that the Chutia people had an advanced culture and administration. The third heritage site, the 400-year-old Tawang Monastery in the extreme north-west of the state, provides some historical evidence of the Buddhist tribal people.
