The Cellular Jail, also known as "Kala Pani," was a colonial prison built by the British in the Andaman Islands to exile and punish Indian freedom fighters. Constructed in 1906, its solitary confinement cells aimed to break prisoners mentally. Revolutionaries like Veer Savarkar and Batukeshwar Dutt were imprisoned here.

The jail symbolizes colonial brutality and India’s struggle for independence. Today, it serves as a national memorial, with a museum and light-and-sound show narrating stories of sacrifice, inspiring patriotism and remembrance among visitors.
