It is one of the Pancha Bootha Sthalam [five elements of Nature] representing Prithivi [Earth]. The Single Mango Tree in the outer court is revered as most sacred and it is believed, if worshipped by childless couple, will be blessed with a child. Hence Lord Shiva is called as Ekambareswarar. It has almost 60 m tall tower that is visible even from the highway while entering into the city.
The temple is dedicated to Lord Shiva. You will be left spellbound after seeing very high gopuram showcasing Dravidian architecture at the entrance. Inside the temple complex there is a long passage with meticulously carved pillars which is a photographer's delight.
