Ross Island Penal Colony Former Andaman Islands convict settlement Ross Island Penal Colony was a convict settlement that was established in 1858 in the remote Andaman Islands by the British colonial government in India, primarily to jail a large number of prisoners from the Indian Rebellion of 1857, also known as the Indian Mutiny. With the establishment of the penal colony at Ross Island, the British administration made it the administrative headquarters for the entire group of Andaman and Nicobar Islands and built bungalows and other facilities on the site. This colony was meant as "manageable models of colonial governance and rehabilitation". The Chief Commissioner's residence was located at the highest point on the island. Over time, several other islands including Chatham and Viper were used for the penal colony. The penal colony became infamous as " Kalapani" or "black water" for the brutalities inflicted by the British authorities on the political prisoners from India, and most of whom had died by 1860 due to illness and torture suffered during the initial stages of the clearance of the forest to establish the colony.
