Twenty-two acre Alcatraz Island in the San Francisco Bay was once a military fortification and then a Federal Prison from 1933 to 1963. It was meant for the most incorrigible criminals in the US and rehabilitation had no part of the prisoner’s sentence. It was strictly a place to remove criminals from US society.
It is a sobering place to tour. The cells had beautiful views of the city of San Francisco and on quiet nights the sounds of the city would reach the island, apparently rubbing salt in the prisoner’s wounds.
