Ananthapura Lake Temple in Kasaragod, built in 9th century, is the only lake temple in Kerala and is the moolasthanam (original abode) of Ananthapadmanabha, the deity of Sree Padmanabhaswamy Temple in Thiruvananthapuram. The sanctum sanctorum of temple is reachable only by a bridge. A crocodile at the temple pond, said to be 150 years old, is a major attraction.
The temple’s lake is also home to a crocodile named Babiya, which is supposed to be the guard of the temple.
The Temple lake or tank in which the Sanctum is situated is a large structure measuring 302 feet square (about 2 acres). There is a cave to the right corner of the lake, which has a gate.
