Tantondreeswara Temple was constructed by the rulers of Chola. The main deity of the temple is Tantondreeswara (Lord Shiva). The area of Nedungadu got its name from Nedunthuyar Theertha Nayaki, the consort of Tantondreeswara. Her name means the one who redressed the long grievances of the people.

In 1948, architectural excavations were conducted in this temple. The officials excavated about 14 Bronze sculptures belonging to 14th century. The excavated bronze idols were of Thirugnanasambandhar, Lord Vinayaga, Manickavasagar, Lord Murugan, Goddess Uma and dancing postures of Lord Shiva such as Ananda Tandavam. This temple from 1971 is regarded as a protected monument.

The entire temple is made up of Red sandstone. The sanctum enshrines the tall idol of Shivalinga which is the main deity, Tantondreeswara. The temple has many inscriptions in the outer walls of the sanctum.

The idols of Nataraja, Sivagamasundari and Manikkavacakar belonging to the temple were stolen in 1959. The Nataraja idol was found 15 days later and reinstalled. A volunteer-collective India Pride Project has traced the remaining idols to few museums/institutions in the Western world.

Similar idol theft was reported from the Varatharaja Perumal temple in the nearby Melakasakudy, beyond the Nattar River, sometime between 1959 and 1962.
