Alcatraz Federal Penitentiary 🇺🇸

Step onto Alcatraz Island, located 1.25 miles off the San Francisco coast, to explore one of America's most infamous historical landmarks. Originally established as an 1850s military fort and military prison, the site was modernized and transformed in 1934 into a maximum-security federal penitentiary designed to hold the nation's most difficult prisoners. Today, this former prison operates as a public museum managed by the National Park Service's Golden Gate National Recreation Area, attracting around 1.5 million visitors annually.

As you walk through the three-story main cellhouse, you will discover cell blocks A through D, where inmates lived in primitive nine-by-five-foot cells lacking privacy. Walk down interior corridors named after famous U.S. streets like Broadway and Michigan Avenue, and peek inside essential facilities including the dining hall, kitchen, library, barber shop, visitation room, and upstairs hospital. You can also see D-Block's severe isolation cells known as "The Hole," used for punishing behavioral problems, alongside historical work structures like the Model Industries Building and New Industries Building where privileged inmates once worked.

A visit offers you a candid look into the intense history and daily realities of this legendary island fortress.
