Achalpuram Temple, situated in the village of Achalapuram, is about 25 km from the temple city of Chidambaram. Lord Shiva is the main deity worshipped in this temple, and the idol worshiped here is to be particularly noted. It is in the form of a Shiva Linga entwined by a snake, made in gold, the hood of which covers the linga, protecting it. Lord Shiva is worshipped as Sri Shivalokathyageshwar in this temple and as always, is accompanied by his consort Goddess Parvathi as Tiruvenneetrumai Ammai.

The temple architecture is reminiscent of the golden age of Tamil temple architecture. Every other temple in Chidambaram exudes the same aura in equal measure and this place proves to be no exception. The temple is located 8 kilometers away from Chidambaram, on the route to Seerkazhi.
