The erection of the Cellular Jail Port Blair , Andaman and Nicobar Island , India commenced in 1898 and finished in 1906. An earthquake in 1941 and the Japanese occupation from March 1942 to October 1954 affected the jail building. At present there are merely three wings and these stand as a quiet monument to the great patriots and martyrs who were captive in this Jail, and sacrificed their lives at the altar of the freedom. In one of the three existing wings of the Jail is located in the District Jail.
The inside walls of the hexagonal brick built construction, of the second floor of the Central Tower of the Cellular Jail, one can unearth the names of more than 336 freedom fighters and revolutionaries who were imprisoned in the Cellular Jail for their patriotic dedication. Every one of these is displayed on the marble slabs. The main entrance, edged by castellated round towers has been renovated.
