Above image:  As you may  see in the image posted above, this temple is on a well-raised platform  above the town and to get into the temple, the devotees have to take the flight of steps. Since the town is at the lower level of  the temple, it is called  Koviladi (in Tamil  Kovil means temple and adi means  below / under)....................

This is believed to be the only Divya Desam  shrine (among the 108) where Neyyappam (a sort of food prepared in ghee) is offered to the Lord every night as neivedhyam. There is a beautiful idol of Santhana Gopalan here. There has been a strong belief that childless couples, upon  holding the small idol of Santhana Gopalakrishnan, sincerely praying and offering butter with sugar to the  deity at the temple  will be  blessed with children.
