Alcatraz Island is located in San Francisco Bay, 1.25 miles offshore from San Francisco, California. The small island was developed with facilities for a lighthouse, a military fortification, a military prison (1868), and a federal prison from 1934 until 1963. Beginning in November 1969, the island was occupied for more than 19 months by a group of Native Americans from San Francisco, who were part of a wave of Native activism across the nation, with public protests through the 1970s. In 1972, Alcatraz became part of a national recreation area and received designation as a National Historic Landmark in 1986.
Alcatraz Island is home to the abandoned prison, the site of the oldest operating lighthouse on the West Coast of the United States, early military fortifications, and natural features such as rock pools and a seabird colony (mostly western gulls, cormorants, and egrets).
Landmarks on the island include the Main Cellhouse, Dining Hall, Library, Lighthouse, the ruins of the Warden’s House and Officers’ Club, Parade Grounds, Building 64, Water Tower, New Industries Building, Model Industries Building, and the Recreation Yard.
