Nadarajar Temple or better known as Sri Nadarajah Alayam was built in the 1930’s, like most temples then it started out  initially as a small shrine and over the years this temple extended it’s structure to accommodate it’s devotees. The main deity is also known as Lord Nadarajar. Lord Nadarajar is a depiction of the Hindu God Shiva as the divine dancer. His dance is called Tandavam.  According to Wikipedia, It typically shows Shiva dancing in one of the Natya Shastra poses, holding Agni (fire) in his left back hand, the front hand in gajahasta (elephant hand) or dandahasta (stick hand) mudra, the front right hand with a wrapped snake that is in abhaya (fear not) mudra while pointing to a Sutra text, and the back hand holding a musical instrument, usually a damaru.
