Kattumannarkoil is a panchayat town and taluk headquarters in Cuddalore district in the Indian state of Tamil Nadu.

As Lord Vishnu came here as King ‘Mannan’ to hold the hand of Mahalakshmi; and later asked Nathamunigal to share the Divya Prabandham and the Vaishnava Sampradayam to the world at large, he was referred to as ‘ Kattum – Mannan – Aanaar’ (the Lord who came as a king and showed the direction to Nathamuni) and the town later became Kattu Mannar.

Like most of coastal Tamil Nadu, the areas adjoining Veeranam tank has a sub-tropical climate receiving most of the rainfall during the North-East monsoons from Oct - Dec.

[citation needed] Veeranam Lake is a major tank attached to Chidambaram Division of South Arcot.

This tank has been referred briefly in the book called " Ponniyen Selvan" Written by the famous author ‘Kalki’ in the year 1950.

[citation needed] When king Paranthaga Cholan I ruled over Chola Kingdom during the 10th century i.e. 907 to 935 AD he wanted to improve the Irrigation facilities in and around Chidambaram.

In addition to that in order to improve the Irrigation facilities in and around the new Village, he formed a new tank and called it as ‘Chola ‘ Gangam’.

The road runs along the side of the Cauvery Canal from Lalpet village to Kumaratchi and is approximately 8.5 kilometres long towards Chidambaram.

The other side road from Lalpet to Sethiathoppu, which is laid around the largest lake Veeranam for around 13 kilometers, would be a very pleasant experience for travellers.
