Social Hall (Alcatraz)

Alcatraz Morgue is the morgue on Alcatraz Island, off the coast of San Francisco, California, United States. It is located on the northwestern side of the island towards the centre, halfway between the Alcatraz Water Tower and the Dining Hall, below the side of the Recreation Yard.

The Former Military Chapel (Bachelor Quarters) is a building on Alcatraz Island off the coast of San Francisco, United States. It is located next to the Sally Port and Dock and the Building 64 residential apartments. It was built in the 1920s in the mission-revival style to accommodate for the officers at the military prison on the island. The ground floor had quarters for the officers and their families who worked at the military prison and the top floor was used as a school and chapel.In 1934, when Alcatraz became a Federal Penitentiary, the building was used as a Bachelor Quarters for unmarried officers.

Alcatraz Dining Hall, often referred to as the Mess Hall, is the dining hall of Alcatraz Federal Penitentiary where the prisoners and staff ate their meals. It is a long wing on the west end of the Main Cellhouse of Alcatraz, situated in the center of the island. It is connected to the block by a corridor known as "Times Square", as it passes beneath a large clock approaching the entrance way to the dining hall. This wing includes the dining hall and the kitchen beyond it.

Alcatraz Hospital is a defunct hospital which was located on Alcatraz Island, California, US. It began operations in the 19th century while the United States Army operated Fort Alcatraz and continued to provide services after the transition to the Alcatraz Federal Penitentiary. Though Alcatraz is now part of the Golden Gate National Recreation Area, the hospital is not included on the general tour.

Alcatraz water tower is on Alcatraz Island in the San Francisco Bay, off the coast of San Francisco, California. It is located on the northwestern side of the island, near Tower No. 3, beyond the Morgue and Recreation Yard. The water tank is situated on six cross-braced steel legs submerged in concrete foundations.

The Recreation Yard was the yard used by inmates of Alcatraz Federal Penitentiary between 1934 and 1963. It is located adjacent to the Dining Hall northwest of the end of D-Block on a raised level surrounded by a high wall and fence above it. Guard Tower #3 lay just to the west of the yard. The gun gallery was situated in the yard, mounted on one of the dining hall's exterior walls. The recreation yard faced the mainland.

United States Penitentiary, Alcatraz Island, also known simply as Alcatraz (English: , Spanish: [alkaˈtɾas] "the gannet") or The Rock, was a maximum security federal prison on Alcatraz Island, 1.25 miles (2.01 km) off the coast of San Francisco, California, United States. The site of a fort since the 1850s, the main prison building was built in 1910–12 as a U.S. Army military prison. The United States Department of Justice acquired the United States Disciplinary Barracks, Pacific Branch, on Alcatraz on October 12, 1933. The island became adapted and used as a prison of the Federal Bureau of Prisons in August 1934 after the buildings were modernized and security increased. Given this high security and the island's location in the cold waters and strong currents of San Francisco Bay, prison operators believed Alcatraz to be escape-proof and America's most secure prison. The three-story cellhouse included the four main cell blocks – A-block through D-block – the warden's office, visitation room, the library, and the barber shop. The prison cells typically measured 9 feet (2.7 m) by 5 ft (1.5 m) and 7 ft (2.1 m) high. The cells were primitive and lacked privacy. They were furnished with a bed, desk, washbasin, a toilet on the back wall, and few items other than a blanket. African Americans were segregated from other inmates in cell designation due to racism during the Jim Crow era. D-Block housed the worst inmates, and six cells at its end were designated "The Hole". Prisoners with behavioral problems were sent to these for periods of often brutal punishment. The dining hall and kitchen extended from the main building. Prisoners and staff ate three meals a day together. The Alcatraz Hospital was located above the dining hall. Prison corridors were named after major U.S. streets, such as Broadway and Michigan Avenue, of New York and Chicago, respectively. Working at the prison was considered a privilege for inmates. Those who earned privileges were employed in the Model Industries Building and New Industries Building during the day, actively involved in providing for the military in jobs such as sewing and woodwork, and performing various maintenance and laundry chores. The prison closed in 1963, but Alcatraz was reopened as a public museum. The island and prison were occupied by Native Americans from 1969 to 1971. It is one of San Francisco's major tourist attractions, attracting some 1.5 million visitors annually. Now operated by the National Park Service's Golden Gate National Recreation Area, the former prison is being restored and maintained.

Fort Alcatraz was a United States Army coastal fortification on Alcatraz Island near the mouth of San Francisco Bay in California, part of the Third System of fixed fortifications, although very different from most other Third System works. Initially completed in 1859, it was also used for mustering and training recruits and new units for the Civil War from 1861 and began secondary use as a long-term military prison in 1868. Major improvements, needed because of changes in artillery, began in the 1870s, but were underfunded and never fully completed, as the post came to be seen less as defense and more as a jail. The site was not used for any major works of the Endicott Board’s plan for the defense of the Bay. A large concrete prison block was erected between 1910 and 1912. In 1933–1934, this was modernized and became the Alcatraz Federal Penitentiary.

In June 1962, inmates Clarence Anglin, John Anglin, and Frank Morris escaped from Alcatraz Federal Penitentiary, a maximum-security prison located on Alcatraz Island in San Francisco Bay. Late on the night of June 11 or early morning of June 12, the three men tucked papier-mâché heads resembling their own likenesses into their beds, broke out of the main prison building via ventilation ducts and an unused utility corridor, and departed the island aboard an improvised inflatable raft to an uncertain fate. A fourth conspirator, Allen West, failed in his escape attempt and remained on the island. Hundreds of leads were pursued by the Federal Bureau of Investigation (FBI) and local law enforcement officials in the ensuing years, but no conclusive evidence has ever surfaced favoring the success or failure of the attempt. Numerous theories of widely varying plausibility have been proposed by authorities, reporters, family members, and amateur enthusiasts. In 1979 the FBI officially concluded, on the basis of circumstantial evidence and a preponderance of expert opinion, that the men drowned in the frigid waters of San Francisco Bay without reaching the mainland. The U.S. Marshals Service case file remains open and active, however, and Morris and the Anglin brothers remain on its wanted list.New circumstantial and material evidence has continued to surface, stoking new debates on whether the inmates managed to survive.

The Occupation of Alcatraz (November 20, 1969 – June 11, 1971) was a 19-month long protest when 89 Native Americans and their supporters occupied Alcatraz Island. The protest was led by Richard Oakes, LaNada Means, and others, while John Trudell served as spokesman. The group lived on the island together until the protest was forcibly ended by the U.S. government. The protest group chose the name Indians of All Tribes (IAT) for themselves. IAT claimed that, under the Treaty of Fort Laramie between the U.S. and the Lakota tribe, all retired, abandoned, or out-of-use federal land was to be returned to the Indigenous peoples who once occupied it. As Alcatraz penitentiary had been closed on March 21, 1963, and the island had been declared surplus federal property in 1964, a number of Red Power activists felt that the island qualified for a reclamation by Indians. The Occupation of Alcatraz had a brief effect on federal Indian Termination policies and established a precedent for Indian activism. Oakes was shot to death in 1972, and the American Indian Movement was later targeted by the federal government and the FBI in COINTELPRO operations.

Alcatraz Island () is a small island 1.25 miles (2.01 km) offshore from San Francisco, California, United States. The island was developed in the mid-19th century with facilities for a lighthouse, a military fortification, and a military prison. In 1934, the island was converted into a federal prison, Alcatraz Federal Penitentiary. The strong currents around the island and cold water temperatures made escape nearly impossible, and the prison became one of the most notorious in American history. The prison closed in 1963, and the island is now a major tourist attraction. Beginning in November 1969, the island was occupied for more than 19 months by a group of Native Americans, initially primarily from San Francisco, who were later joined by AIM and other urban Indians from other parts of the country, who were part of a wave of Native American activists organizing public protests across the US through the 1970s. In 1972, Alcatraz was transferred to the Department of Interior to become part of Golden Gate National Recreation Area. It was designated 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. Visitors can reach the island by ferry ride from Pier 33, located between the San Francisco Ferry Building and Fisherman's Wharf, San Francisco. Hornblower Cruises, operating under the name Alcatraz Cruises, is the official ferry provider to and from the island. Alcatraz Island is the site of the abandoned federal prison, 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 Power House is an electrical supply building on the northwest coast of Alcatraz Island, off the coast of San Francisco, USA. It was constructed in 1939 for $186,000 as part of a $1.1 million modernization scheme which also included the water tower, New Industries Building, officers quarters and remodeling of the D-block. The white powerhouse smokestack and lighthouse were said to give an "appearance of a ship's mast on either side of the island". "A Warning. Keep Off. Only Government permitted within 200 yards" sign lay in front of the powerhouse to deter people landing on the island at the point. Between 1939 and 1963 it supplied power to the Federal Penitentiary and other buildings on the island. The powerhouse had a tower duty station which was guarded with a "30-caliber Winchester rifle with 50 rounds of ammunition, a Colt .45 semiautomatic pistol with three seven-round magazines, three gas grenades, and a gas mask."
