About this subject
Alcatraz Island, located in San Francisco Bay, California, served as a military fort before becoming the most feared federal prison in the United States. Known as "The Rock," the penitentiary housed notorious criminals such as Al Capone, George "Machine Gun" Kelly, and Robert Stroud, the "Birdman of Alcatraz." The island was chosen for its natural isolation: the cold waters and strong currents made escape nearly impossible.
Built as the prison of last resort, Alcatraz operated under a regime of solitary confinement and strict discipline. Inmates spent up to 23 hours a day in cells measuring 9 feet by 5 feet. Despite the security, there were 14 recorded escape attempts; the most famous was in 1962, when Frank Morris and the Anglin brothers escaped using makeshift rafts. The case was popularized by the film "Escape from Alcatraz" starring Clint Eastwood. To this day, the three have never been found, and the FBI closed the case in 1979.
The prison closed in 1963 due to high operating costs and facility deterioration. In 1972, the island became part of the Golden Gate National Recreation Area, and today it is one of San Francisco's most visited tourist attractions. Visitors can explore the cells, cafeteria, and library, and listen to recordings from former inmates and guards recounting daily life. The panoramic view of the city and the Golden Gate Bridge contrasts with the site's grim atmosphere.
Alcatraz also has ecological importance: it hosts one of the largest nesting colonies of the black-crowned night heron in North America. Since 2019, the island has hosted a light installation called the "Alcatraz Light Show," projecting messages of hope and freedom onto the prison walls at night.
