What to know

Alcatraz Island, famously nicknamed 'The Rock,' is a National Historic Landmark situated in the middle of San Francisco Bay. Long before its fame as a federal prison, the island was named 'Alcatraces' by Spanish explorer Juan Manuel de Ayala in 1775. Its strategic location led to a presidential order in 1850 setting the land aside for military use, where it served as a Civil War fortress and the site of the first lighthouse on the West Coast. From 1909 through 1911, military prisoners constructed a new facility designated as the Pacific Branch, U.S. Disciplinary Barracks for the U.S. Army. The U.S. Army operated the site until 1933, at which point it transferred to the Department of Justice. From August 1934 until March 21, 1963, it functioned as a federal penitentiary for incorrigible inmates, including the notorious Prohibition-era crime boss Al Capone. The facility eventually closed due to the high costs of transporting fresh water to the island and removing waste. In 1972, the site was added to the Golden Gate National Recreation Area and opened to the public in 1973. Beyond the cellblocks, the island holds significance as the birthplace of the American Indian Red Power movement. Today, visitors explore a blend of history and nature. The island features historic gardens, tide pools, and nesting bird habitats. Modern exhibits now address environmental and social issues, transforming the former prison into a cultural attraction that welcomes approximately 1.4 million visitors annually.
