The granite cave encloses a one-celled shrine with a loose sculpture of Vinandhara Dakshinamurthi. The outer wall of the cave depicts half-complete reliefs of the Hindu God Shiva with Goddess Parvathi.
It is about 17 kilometers from the city centre. The cave was left unnoticed for a number of years.
