Alcatraz was only a prison??

Island (/ˈælkəˌtræz/) is located in San Francisco Bay, 1.25 miles (2.01 km) offshore from San Francisco, California, United States.[1] The small island was developed with facilities for a lighthouse, a military fortification, a military prison, and a federal prison from 1934 until 1963.[4] 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.
