Island in San Francisco Bay, California, US
Alcatraz Island is a small island about 1.25 miles offshore from San Francisco in San Francisco Bay, California, near the Golden Gate Strait. The island was developed in the mid-19th century with facilities for a lighthouse, a military fortification, and a military prison. In 1934, the island was converted into a federal prison, Alcatraz Federal Penitentiary. The strong tidal currents around the island and cold water temperatures made escape nearly impossible, giving the prison one of the most notorious reputations of its kind in American history. The prison closed on March 21, 1963, leaving the island a major tourist attraction today with nearly 1.4 million people visiting the island annually.
Alcatraz reveals stories of American incarceration, justice, and our common humanity. This small island was once a fort, a military prison, and a maximum security federal penitentiary. In 1969, the Indians of All Tribes occupied Alcatraz for 19 months in the name of freedom and Native American civil rights. We invite you to explore Alcatraz's complex history and natural beauty.
