What is the name of the Island located in San Francisco Bay, 1.25 miles offshore, with facilities for a lighthouse, a military prison, and the Parade Grounds, a large concrete open area?
Alcatraz Island Alcatraz Island ( ) is located in San Francisco Bay, 1.25 mi offshore from San Francisco, California, United States. 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.
