The presiding deity is Dharbaranyeswarar(Lord Siva) and is believed to have been made of dharba grass.
 The worship is also centered around the icon of planet saturn, called Shani, originally treated as the door keeper of the shrine.
 According to Hinduism, saturn resides in each rasi(zodiac) for two and half years.
The tradition is to worship Shani before entering the inner sanctum of Lord Siva.
