Thiruchendur Murugan Temple is the prime attraction of the town. It is considered to be one of the six holy abodes of Lord Murugan. The temple is dedicated to Lord Murugan and his consorts Valli and Deivanai. The temple also houses shrines dedicated to Lord Shiva and Lord Vishnu. The temple is said to have existed since the Vedic period and has been mentioned in several ancient texts.
The temple has a towering nine-tiered Gopuram or main entrance. A Nazhi Kinaru, a sacred well, constructed around a freshwater spring is found in the temple premises. Lord Murugan, who is expressed as Senthilandavar, faces the east although the entrance of the temple is towards the south. The unique feature of this temple is that it is the only Murugan Temple situated on the seashore while all the rest are located on hill tops and forests in India.
Festivals, such as Brahmotsavam, Vasanthotsavam, Visakha Visakam, Skandha Sasthi, Aavanipperunithirunaal, Maasipperunthirunaal and Oonjal Sevai, are celebrated with pomp and glory and are important pilgrim attractions.
