Though well-established as a centre of Chhinnamasta by the 18th century, the site is a popular place of worship among tribals since ancient times.

The temples of Mahavidyas built in a series nearby are Tara, Shodashi, Bhuvaneswari, Bhairavi, Bagla, Kamla, Matangi, Dhumavati.

The temple is very old and is flocked by devotees from Bihar, Jharkhand, West Bengal Assam and Nepal for worship of Goddess Chinnamastika.
