The Cellular Jail, also known as Kala Pani literally ‘black water’, in the sense of deep sea and hence exile, was a colonial prison situated in the Andaman and Nicobar Islands, India. The prison was used by the British especially to exile political prisoners to the remote archipelago. Many notable freedom fighters such as Batukeshwar Dutt and Veer Savarkar, among others, were imprisoned here during the struggle for India’s independence. Today, the complex serves as a national memorial monument.
Although the prison complex itself was constructed between 1896 and 1906, the British had been using the Andaman islands as a prison since the days in the immediate aftermath of the Sepoy Mutiny of 1857.
