Mariamman Theppakulam was built in 1636.This huge tank also known as the Mariamman tank is at the eastern end of the city and is almost equal in area to that of the Meenakshi Amman temple. There is a mandapam in the centre of the tank enshrining Lord Vigneswara.
This idol was found here when earth was being dug for the Thirumalai Nayakar Mahal. A tank was created in this area with the Ganesha idol. This tank is fed with water from the Vaigai through an ingenious system of underground channels. A colorful float festival is held on Thai Poosam day (in January/February) to celebrate the birth anniversary of Tirumalai Nayakar.
