The Thanthania Kalibari was founded by Shankar Ghosh (whose grandson was Swami Subhodhananda,[2] a direct disciple of 19th century mystic Ramakrishna) in 1803, as mentioned in the temple building itself.[3] However, according to a different tradition it was built in 1703. The image of the presiding deity Siddheshwari is made of clay and the idol is painted every year with the colors red and black. Tuesdays and Saturdays are considered auspicious for a visit to the temple. The temple is 300+ years old and the idol is even older.
