Alcatraz, the maximum-security federal prison on an island in San Francisco Bay, housed notorious criminals like Al Capone and inspired myths about impossible escapes.
About this subject
Alcatraz Island, located in San Francisco Bay, California, was originally a military fort before becoming a military prison in the mid-19th century. In 1934, the U.S. federal government repurposed it as the Alcatraz Federal Penitentiary, designed to hold the most dangerous and habitual criminals in the federal prison system. The facility operated until 1963, when it was closed due to high operational costs and deteriorating infrastructure.
During its 29 years of operation, Alcatraz housed approximately 1,500 prisoners, including legendary crime figures such as Al Capone, George "Machine Gun" Kelly, and Robert Stroud, the "Birdman of Alcatraz". Conditions were extremely harsh: inmates were confined to individual cells measuring just 2.7 m², with limited visits and activities. Discipline was enforced through isolation and severe punishments, which cemented Alcatraz's reputation as an inescapable prison.
Despite its reputation, there were 14 escape attempts. The most famous occurred in June 1962, when Frank Morris and brothers John and Clarence Anglin escaped through a tunnel carved into their cells. They were never found, sparking decades of speculation. The FBI concluded they drowned in the cold bay waters, but no definitive confirmation ever emerged.
After the prison closed, the island was occupied by Native American activists from 1969 to 1971. In 1973, Alcatraz became part of the Golden Gate National Recreation Area and is now one of the most visited tourist attractions in the United States, receiving over 1.4 million visitors annually. Guided tours include the cells, dining hall, and isolation areas, preserving the somber atmosphere that marked its history.
