Kalapani Cellular Jail is located in Port Blair, the capital city of the Andamans in India. More than 350 km. Mr. The Andaman Islands are a group of 180 islands, both large and small. The cellular prison, built of granite, is built in such a way that prisoners cannot see or communicate with each other. The convicts, who had led the struggle without surrendering to the British under any circumstances, were deported to cellular prisons. The verandas can only be reached by passing through two or three gates with thick iron bars. There is also a circular watchtower that stands out as the focal point of it all.
