According to the art historian George Michell, the temple is a typical 9th-10th century Nolamba construction with pilasters on the outer walls of the shrines, perforated decorative stone windows which contain figures, of a dancing Shiva (south wall of the Arunachaleshwara shrine) and Durga standing on a buffalo head (north wall of Bhoga Nandeshwara shrine). Pyramidal and tiered towers (shikhara) rise from the two major shrines. Each major shrine has a large linga in the sanctum (the universal symbol of the god Shiva) with a sculpture of Nandi (the bull) in a pavilion facing the shrine. According to Michell, during the 16th century Vijayanagara period, a pavilion with elegant pillars was added in between the two major shrines. The pillars crafted out of grey-green granite have relief sculptures of attendant maidens. Michell feels the minor "Uma-Maheshwara" shrine was added in between the two major shrines (behind the pavilion) during the post Vijayanagara rule of the Gowdas of the Yelahanka dynasty. The minor shrine has a procession of deities and sages in wall relief. The wall that links the two major shrines was cleverly constructed so as to be in-distinguishable from the two original shrines. A spacious pillared hall was also added in front of the two major shrines.
