Sarpa Kavu
A sarpa kavu or naga banna is a traditional sacred grove found near ancestral homes in Kerala and Tulunad regions of South India. These groves are believed to be inhabited by snakes, and typically contain representations of a nagaraja and other serpentine deities within stone houses. Ritual offerings and ceremonies are conducted at these sites, which are maintained and revered by communities such as the Bunts and Nairs. Access to the groves is generally restricted except during religious observances.Legend
According to the Keralolpati, the land of Kerala was reclaimed from the Arabian Sea by Parashurama, the sixth avatar of Vishnu. Following his extermination of the Kshatriya class, Parashurama established sixty-four villages for Brahmins in the region. The land was, however, inhabited by nagas, a serpent-like race, which posed a threat to the Brahmins. Seeking guidance, Parashurama prayed to Shiva, who advised him to propitiate the serpent king Vasuki by travelling to the subterranean realm of Patala. An accord was reached between humans and nagas: the nagas were instructed to vacate the areas designated for human settlement and occupy anthills and burrows instead. In return, humans were required to designate portions of their homes for the worship of snakes. These preserved areas subsequently evolved into small forested groves known as sarpa kavu.
