Lonely Planet review
The main temple stands on the eastern side of the hilltop. Constructed of laterite and brick with carved lintels of sandstone, the complex is surrounded by the partially ruined walls of a 2.5m-wide gallery with windows.
Inscriptions found here date from the 11th century, when this site was known as Suryagiri. The wooden doors to the sanctuary in the centre of the complex, which open to the east, are decorated with carvings of figures standing on pigs. Inside the sanctuary are statues of Buddha.
Curiously the USaround US$3 charge is not levied at the bottom of the hill, but at the temple, so it is technically free to visit if you pass on the old brick structure.
