Sri Kamakshi Temple
There is a very ancient Kamakshi Temple here. It is called Moongilanai Kamakshi temple. The main door of this temple is never opened and poojas are performed only to the door. The name Devadanapatti stands for devadanam + patti, which means donated to God in Tamil. Maha Shivaratri (Tamil month of Masi) on March is the only festival which is celebrated in this temple. This temple story is described in the Tamil movie "Mahashakti Mariamman". 
Nearby this temple, there is a temple for Lord Karupannaswamy.
There is saying that buttermilk will not be available in this town even it has three time harvests in a year. A story is behind this saying. It goes like this: Once a monk visited this village and went on begging. But no body gave alms. In angry mood the monk cursed the village as it will not flourish even it has great natural resources. People here believe it.
North and east side of the town has panoramic view as there is irrigated landscape. There is a scene of paddy fields, sugar hand, plantain fields and coconut tree groves. Water for agriculture is supplied through the canal and the check dams across the river from Manjalar Dam which is built down under the Kodaikanal hills. Water from the rivers Varattaru, Thalaiyaru and Iruttaaru fill the dam.
As families, villagers from nearby Genguvarpatti come by 'maattu vandi'[bullok cart] during summer every year , cook at the temple premises, take bath in the nearby falls and then conduct uchchi kaala pooja at the amman temple and partake common cooked food for all. At this pooja they pray for rains as well as welfare of all villages in and around. As soon as the aarthi is done, without fail a 'palli' will answer the prayers which can be witnessed personally. The pleasure of having bath under the water source nearby is better experienced than can be explained which is equivalent to taking three baths in courtalam aruvi itself. !!
