"Existing architectural remains, decorated mouldings on the walls, karna-ratha and prati-ratha of central chamber, a large decorated entrance gate with torana on the eastern wall of the western chamber, a small entrance with mutilated image on lalatbimba, birds and animals carved for decoration in and outside suggest that the western wall is remaining part of a Hindu temple. Based on art and architecture, this pre-existing structure can be identified as a Hindu temple."
