Alcatraz Island is located in San Francisco Bay, 1.25 miles (2.01 km) offshore from San Francisco, California, United States. The small island was developed with facilities for a lighthouse, a military fortification, a military prison, and a federal prison from 1934 until 21 March 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 American activism across the U.S., with public protests through the 1970s. In 1972, Alcatraz became part of Golden Gate National Recreation Area and received designation as a National Historic Landmark in 1986.
