Viper Island is adjacent to Port Blair. It is named after the British trading ship that was wrecked nearby in the 19th century. A path leads to the remnants of the yellow coloured brick jail and the gallows built by the British in 1867.
Viper Island is of much historical importance because the first jail was constructed at this island where the offenders were sent to serve their punishment. After the Cellular Jail was made, the convicts were transferred there.
You can go and explore the cells where the prisoners were kept in Viper Island at Andaman and Nicobar Islands. The gallows is sited at the top of the mound. It is the place where the people sentenced to death were hanged till death. One of the very famous freedom fighter Sher Ali, who killed the Lord Mayo, the Viceroy of India in 1872 , was hanged here.
