Named after the vessel by the name of Viper who carried Lieutenant Archibald Blair to this island in the year of 1789, this island, though beautiful, has a dark past. The palace was used to imprison political prisoners and torture them till they were hung at the gallows. The place was abandoned when the Cellular Jail was established. Those dilapidated; the jail still stands here to remind one of the past glory and torture faced by the Indian freedom fighters. This place should be included on your list of things to do when one is in Andaman and Nicobar Islands. The place is beautiful and is many tourists pay it a visit.
