The first Paranthaka Chozha alias Veeranarayanan renewed Sri Mannanarkoil by brick construction. But there is authority to prove that Mannanar Perumal Temple was in existence even before the Chozha king paranthakan (Uthama Chozhan's 16th year stone inscription).

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. Hot weather prevails in the summer months from March to June, and the maximum temperature varies from 30–38 °C. Being close to the coast cyclones that strike the area have a profound impact, resulting in heavy rains. Two rainfall monitoring stations are located in Veeranam Tank one at its right bank i.e. Kattumannarkoil and another at left bank i.e. Sethiathope. The average rainfall in these stations is more than the state average of 950 mm. During the last 18 years the average annual rainfall in Kattumannarkoil is 1025 mm. In Sethiathope, the average annual rainfall during the last 25 years is 1273 mm. But due to the vagaries of the North-East monsoon, Veeranam tank often has to depend on water from Mettur dam.

Veeranam Tank is one of the biggest tanks in Tamil Nadu and also an age old one. This tank has been referred briefly in the book called " Ponniyen Selvan" Written by the famous author ‘Kalki’ in the year 1950. This book gives the information on the age of this tank and it has been mentioned that the tank was formed at a period of more than 1000 years by the Prince Rajathithar Son of Parandage Chola. The tank was originally called as Veeranarayanan Tank.

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. He formed a village called as ‘Veera Narayana Sathurvethi Mangalam. This Village was gifted to the Scholars who were well versed in the Four Vedhas. This Village is now called as Kattumannarkoil which is situated in the right flank of Veeranam Tank. He then formed the biggest tank and named it as ‘Veera Narayanan Eri’ ‘Veera Narayanan’ is the nickname given to king Paranthaga Cholan I for his Valour. Subsequently, this tank is now called Veeranam Tank.

During the later period of Chola Kingdom, King Rajendra Cholan I who ruled during the period 1012 AD to 1044 AD, Spread his kingdom up to Ganges. He conquered the lands up to River Ganges. In Memory of his Victory he formed the Village ‘ Gangai Konda Cholapuram’ during the year 1024 AD. 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’. He made a link between ‘Chola gangam’ and Veeranarayanan Eri so that the former surpluses into the later. The tank ‘Chola Gangam’ is now called as ‘ Ponneri Tank’ which is situated at the road connecting Jeyamkondam and Gangaikonda Cholapuram. These details were collected from Saraswathi Mahal Library at Tanjore.
