The main sanctury is surrounded by an outer and inner gallery, with arched gateways.
The last Naga Bridge links the middle arched gateway of the inner gallery with the antechamber of the principal tower.
The principal tower stands exactly at the center of the ancient temple complex. While the eastern side is formed by the Mandapa or antechamber, there are double porches built in the north, south and west of the tower. In the inner sanctum the Shiva Lingam was located. The Somasutra, or water conduit, used to drain away sacred water during religious rites, still is there.
