Vandiyur Mariamman Teppakulam is the pond located near about 2 km from the Meenakshi Amman Temple. The pond is connected to Vaigai River through an ingenious system of underground Channels. It has total of 12 long stairs (steps) made of granite on all four sides. The temple as well as the stairs was built by the King Thirumalai Nayak. In the centre of the tank there is a Mandapam called Maiya Mandapam (Central Mandapam) with Vinayakar temple and garden. This is the location where the king Thirumalai Naicker excavated the soil to fabricate the bricks required for constructing his palace. The pit that was thus formed is seen as tank now.
