Kali Temple
Kalighat is the temple from which Kalikata takes its name (anglicized to Calcutta). The temple was constructed over an older temple in 1809. A legend narrates that when the corpse of Shiva's wife was cut up one of her fingers fell down. It has been an important pilgrimage site since then.

Kali stands for the destructive side of Shiva's consort and demands sacrifices daily. Every morning goats are slain to satisfy her yearn for blood. Poor people come here during the day for free food.

Mother Teresa's Hospital for the Dying Destitute is right next door to the temple and volunteers and travelers are welcome to visit. The temple is 2km south of St Paul's Cathedral and is easily accessible by metro (Kalighat station).

Belur Math
Belur Math is situated on the West Bank of Hoogly River. It is the headquarters of the Ramakrishna Mission. Ramakrishna preached the unity of all religions. His follower Swami Vivekananda founded the Ramakrishna Mission in 1897. They have branches all over the country. The movement's international headquarters was founded in 1899. It is supposed to represent a church, a mosque and a temple, depending on how you look at it.

Dakshineswar Kali Temple
North of Belur Math is the Kali temple that was built in 1847. This is the very temple where its priest Ramakrishna reached his spiritual vision of the unity of all religions. Twelve more temples dedicated to Lord Shiva surround the temple.
