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 (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.
The first Spaniard to document the island was Juan Manuel de Ayala in 1775, who charted San Francisco Bay and named one of the three islands he identified as the "La Isla de los Alcatraces," which translates as "The Island of the Pelicans," from the archaic Spanish alcatraz (in English: "pelican").
Over the years, the Spanish version "Alcatraz" became popular and is now widely used. In August 1827, French Captain Auguste Bernard Duhaut-Cilly wrote "... running past Alcatraze's (Pelicans) Island ... covered with a countless number of these birds.
A gun fired over the feathered legions caused them to fly up in a great cloud and with a noise like a hurricane."The California brown pelican (Pelecanus occidentalis californicus) is not known to nest on the island today. The Spanish built several small buildings on the island and other minor structures.
Because the penitentiary cost much more to operate than other prisons (nearly $10 per prisoner per day, as opposed to $3 per prisoner per day at Atlanta),[27] and half a century of salt water saturation had severely eroded the buildings, then Attorney General Robert F. Kennedy ordered the penitentiary closed on March 21, 1963.
In addition, citizens were increasingly protesting the environmental effects of sewage released into San Francisco Bay from the approximately 250 inmates and 60 Bureau of Prisons families on the island.
