The Cellular Jail (known as Kala Pani) was a colonial prison built in the Andaman and Nicobar Islands, India, between 1896 and 1906.
The structure of the jail consisted of seven wings (3-storey high), made of bricks brought all the way from Burma. These wings intersected in the middle at a tower, which was used for keeping a watch on inmates who were political prisoners fighting for India’s freedom struggle.
Amazing Fact: The jail received its name, ‘Cellular Jail’, from the solitary cells in which prisoners were kept so as to prevent them from communicating.
