The entireshrine, from the circuler base to the Sikhara, is built of brick and plaster. No adhistana is visible. The cornice has two rows of simhalalata gables. The circular gala shows paintings of the Nithyasuris and hamsas. Though the garbhagriha is circular, the vimana is oval-shaped, or ellipsoidal, slightly elongated west to east.
The sikhara is topped by a row (West-east) of four kalasas, said to represent Vasudeva,Sankarshana, PradYumna, and Anirudha,. Each gable set in a slight offset carries a kalasa just behind the simhalalata. The gables contain the figures of standing Vishnu in the west (Achyuta), standing Vishnu with the hoods of Adisesha above in the north (Ananta) and Venugopala in the ease (Govinda). On the southern side, the offset is much larger (6 feet in length) and covers the antaralabelow. This is topPed by a row (north-south) of four kalasas and ends up with a gable containing the image of Paravasudeva. The image of Paravasudeva appears above a pedestal and niche. The entire vimana with all the Parts described above are covered with gold plates.
The oval vimana with its southern offset yields the wellknown Pranavakara. The Paramesvara samhita of the Pancaratragama declares that, among the different types of prasadas, the vrittaYata or the ellipsoidail type is the best.
The 1000-pillared MandaPa (Thirumamani MandaPam): This was built, according to the Koil Olugu, by Perumaldevan under the authority of Kampaya Dandanayaka, the chief minister of Hoysla Ramanatha (1263-1295). An inscription dated 1396 says that Annappar Chaundappa repaired the mandapa and consecrated Vitthala therein.
