Numaligarh is prominently known as one of the archaeologically rich places of the state because of the historical remains of the ancient temple and sculptures that were excavated from the top of the Deopahar.

[3] Deopahar, also called Deoparvat, is situated by the side of the Asean Highway 1(NH -129) in Numaligarh, Golaghat district, Assam, India.

[1] Inscriptions of the Kamarupi kings were found on an ancient copper plate which suggested it belonged to a place called 'Joyscandavar in Happaka'.

[1] Suhunmung Dihingia Raja (1497-1539) alias Swargadeo Swarganarayan built the fort of Numaligarh in this area under the influence of an evil spirit.

[6][7] An English tea planter named Thomas Guardthei was the first to highlight the significance and complexity of the unique sculpture and architecture of the broken Shiva temple at Deopahar.

The temple has a big ceiling slab engraved with a large lotus bearing a relief of Vidyadhara holding a scarf and a necklace by both hands.

Other sculptural representation found are of Kirtimukha, Kalamakaras, Fangananm Shiva, Sridhar Rudra, Lakshmi-Narayana, Hara-Gauri Rashlila, Sarpadevata, Pranayam dhyan, Padma Sakra, Ram and Ravana, Sugriva etc.
