Alcatraz Island, San Francisco Bay, California, United States

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. The water currents around the island were high at all times, which presumably decreased the chance of an inmate escaping.

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 activists organizing public protests across the US through the 1970s. In 1972, Alcatraz became part of Golden Gate National Recreation Area and received designation as a National Historic Landmark in 1986.

Today, the island's facilities are managed by the National Park Service as part of Golden Gate National Recreation Area; it is open to tours. Visitors can reach the island in a little under 15 minutes by ferry ride from Pier 33, located between the San Francisco Ferry Building and Fisherman's Wharf, San Francisco. Hornblower Cruises and Events, operating under the name Alcatraz Cruises, is the official ferry provider to and from the island.

Alcatraz Island is home to the abandoned prison, the site of the oldest operating lighthouse on the West Coast of the United States, early military fortifications, and natural features such as rock pools and a seabird colony (mostly western gulls, cormorants, and egrets). According to a 1971 documentary on the history of Alcatraz, the island measures 1,675 feet (511 m) by 590 feet (180 m) and is 135 feet (41 m) at highest point during mean tide.The total area of the island is reported to be 22 acres (8.9 ha).

Landmarks on the island include the Main Cellhouse, Dining Hall, Lighthouse, the ruins of the Warden's House and Social Hall, Parade Grounds, Building 64, Water Tower, New Industries Building, Model Industries Building, and the Recreation Yard.

The first European to document the islands of San Francisco Bay was Spanish naval officer and explorer Juan Manuel de Ayala during Spanish rule of California, who charted San Francisco Bay in 1775. He named today's Yerba Buena Island "La Isla de los Alcatraces", which translates as "The Island of the Gannets" but is commonly believed to translate as "The Island of the Pelicans (Spanish for Pelicans is Pelícanos)",from the archaic Spanish alcatraz ("pelican"). Yerba Buena Island's name appeared on Ayala's 1775 chart of San Francisco Bay as "Isla de Alcatraces", but was later transferred to the rock now known as Alcatraz Island by Captain Beechey, an English naval officer and explorer.

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 is not known to nest on the island today. The Spanish built several small buildings on the island and other minor structures.

The earliest recorded private owner of the island of Alcatraz is Julian Workman, to whom it was given by Mexican governor Pio Pico in June 1846, with the understanding that Workman would build a lighthouse on it. Julian Workman is the baptismal name of William Workman, co-owner of Rancho La Puente and personal friend of Pio Pico. Later in 1846, acting in his capacity as Military Governor of California, John C. Frémont, champion of Manifest Destiny and leader of the Bear Flag Republic, bought the island for $5,000 in the name of the United States government from Francis Temple. In 1850, President Millard Fillmore ordered that Alcatraz Island be set aside specifically as a United States military reservation, for military purposes based upon the U.S. acquisition of California from Mexico following the Mexican–American War.Frémont had expected a large compensation for his initiative in purchasing and securing Alcatraz Island for the U.S. government, but the U.S. government later invalidated the sale and paid Frémont nothing. Frémont and his heirs sued for compensation during protracted but unsuccessful legal battles that extended into the 1890s.

Following the acquisition of California by the United States as a result of the Treaty of Guadalupe Hidalgo (1848) which ended the Mexican–American War, and the onset of the California Gold Rush the following year, the U.S. Army began studying the suitability of Alcatraz Island for the positioning of coastal batteries to protect the approaches to San Francisco Bay. In 1853, under the direction of Zealous B. Tower, the United States Army Corps of Engineers began fortifying the island, work which continued until 1858, when the initial version of Fort Alcatraz was complete. The island's first garrison, numbering about 200 soldiers, arrived at the end of that year.

When the American Civil War broke out in 1861, the island mounted 85 cannons (increased to 105 cannons by 1866) in casemates around its perimeter, though the small size of the garrison meant only a fraction of the guns could be used at one time. At this time it also served as the San Francisco Arsenal for storage of firearms to prevent them falling into the hands of Confederate sympathizers.Alcatraz, built as a "heavily fortified military site on the West Coast", was to form a "triangle of defense" with Fort Point and Lime Point, but the contemplated work on Lime Point was never built. The first operational lighthouse on the West Coast of the United States was also built on Alcatraz. During the war, Fort Alcatraz was used to imprison Confederate sympathizers and privateers on the west coast, but never fired its guns at an enemy.

“Binghamton University archaeologist Timothy de Smet and colleagues located historical remains beneath the former recreation yard of the Alcatraz Federal Penitentiary.” Using ground-penetrating radar data and georectifications, Smet and colleagues uncovered structures, including “a “bombproof” earthwork traverse along with its underlying vaulted brick masonry tunnel and ventilation ducts,” in surprisingly good condition. Archaeologists also found the remains of ammunition magazines, and tunnels below the penitentiary that was built later.

Because of its isolation from the outside by the cold, strong, tremendous currents of the waters of San Francisco Bay, Alcatraz was used to house soldiers who were guilty of crimes as early as 1859. By 1861, the fort was the military prison for the Department of the Pacific and housed Civil War prisoners of war (POWs) as early as that year. Starting in 1863, the military also held private citizens accused of treason, after the writ of habeas corpus in the United States was suspended.

The United States Disciplinary Barracks on Alcatraz were acquired by the United States Department of Justice on October 12, 1933, and the island became a federal prison in August 1934. Alcatraz was designed to hold prisoners who continuously caused trouble at other federal prisons. At 9:40 am on August 11, 1934, the first batch of 137 prisoners arrived at Alcatraz, arriving by railroad from the United States Penitentiary in Leavenworth, Kansas to Santa Venetia, California, before being escorted to Alcatraz, handcuffed in high security coaches and guarded by 60 special FBI agents, U.S. Marshals and railway security officials.

Most of the prisoners were notorious bank robbers and murderers. The prison initially had a staff of 155, including the first warden James A. Johnston and associate warden J. E. Shuttleworth, both considered to be "iron men". The staff were highly trained in security, but not rehabilitation.

During the 29 years it was in use, the jail held some of the most notorious criminals in American history, such as Al Capone, Robert Franklin Stroud (the "Birdman of Alcatraz"), George "Machine Gun" Kelly, Bumpy Johnson, Rafael Cancel Miranda (a member of the Puerto Rican Nationalist Party who attacked the United States Capitol building in 1954), Mickey Cohen, Arthur R. "Doc" Barker, and Alvin "Creepy" Karpis (who served more time at Alcatraz than any other inmate). It also provided housing for the Bureau of Prisons staff and their families.

There are several reasons that Alcatraz closed as a penitentiary in 1963: 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); half a century of salt water saturation had severely eroded the buildings; and three people had escaped in 1962.

Today, American Indigenous groups, such as the International Indian Treaty Council, hold ceremonies on the island, most notably, their "Sunrise Gatherings" every Columbus Day and Thanksgiving Day.

The Global Peace Foundation proposed to raze the prison and build a peace center in its place. During the previous year, supporters collected 10,350 signatures that placed it on the presidential primary ballots in San Francisco for February 5, 2008. The proposed plan was estimated at $1 billion. For the plan to pass, Congress would have to have taken Alcatraz out of the National Park Service. Critics of the plan said that Alcatraz is too rich in history to be destroyed. On February 6, 2008, the Alcatraz Island Global Peace Center Proposition C failed to pass, with 72% of voters rejecting the proposition.

The coastal environment of the San Francisco Bay Area has caused deterioration and corrosion of building materials throughout Alcatraz. Beginning in 2011, the National Park Service began major renovations on the island, including the installation of solar panels on the cell house roof, slope stabilization near the Warden's House and the stabilization and rehabilitation of the outer cell house walls.

One of San Francisco's major tourist attractions, Alcatraz drew some 1.7 million visitors annually according to a 2018 report. Visitors arrive by ferry, operated under contract by Alcatraz Cruises LLC at Pier 33. The 2018 report indicated that "former prison buildings are being conserved and seismically upgraded and additional areas of the Island are opened to the public as safety hazards are removed"
