Answer 1

Alcatraz Island is located in the San Francisco Bay, 1.5 miles (2.4 km) offshore from San Francisco, California, United States.

"The Rock" the small island was developed as a lighthouse, a military fortification, a military prison (1868), and a federal prison from 1933 until 1963. In November 1969, the island became occupied for more than 19 months by a group of Aboriginal Peoples 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 a national recreation area and received designation as a National Historic Landmark in 1986.
