New Industries Building

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."

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.

Little Alcatraz is a small rock in San Francisco Bay roughly 81 yards (74 m) off the Model Industries Building off northwest coast of Alcatraz Island. Due to its proximity to the island it is known by this name, but it was formerly known as Paul Pry Rock due to the steamer Paul Pry striking it on December 22, 1862, with some 150 men on board. On January 14, 1868, the 700 ton British ship, Oliver Cutts, struck the rock and sank. Since it is submerged at high tides, Little Alcatraz is still routinely struck by small pleasure boats.The rock is often a resting ground for Brandt's cormorants. During the last escape attempt from Alcatraz on December 16, 1962, Darl Lee Parker was found on Little Alcatraz; he couldn't swim. Some members of the South End Rowing Club also refer to the pier west of Municipal Pier/Aquatic Park as "Little Alcatraz" because it was the pier that connected prisoners and goods from San Francisco to Alcatraz.

The Model Industries building or Industries Building is a three/four-story building on the northwest corner of Alcatraz Island off the coast of San Francisco, USA. This building was originally built by the U.S. military and was used as a laundry building until the New Industries Building was built as part of a redevelopment program on Alcatraz in 1939 when it was a federal penitentiary. As part of the Alcatraz jail, it held workshops for inmates to work in. On January 10, 1935, the building shifted to within 2.5 feet from the edge of the cliff following a landslide caused by a severe storm. The warden at the time, James A. Johnston, proposed to extend the seawall next to it and asked the Bureau for $6500 to fund it. He would later claim to dislike the building because it was irregularly shaped. A smaller, cheaper riprap was completed by the end of 1935.A guard tower and a catwalk from Hill Tower was added to the roof of the Industries Building in June 1936 and the building was made secure with bars from old cells to bar the windows and grill the roof ventilators and to prevent inmates from escaping from the roof. It ceased use as a laundry in 1939 when it was moved to the upper floor of the New Industries Building. Today the building is heavily rusted due decades of exposure to the salt air and wind and the Hill Tower no longer exists. The guard tower formerly located on top of the building now sits across from the Power plant where it is on display.

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 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.

Barker Beach is a small beach and rocky coastal area on the west side of Alcatraz Island, off the coast of San Francisco, California. It lies south of the long two-story New Industries Building. During the foggy, early morning hours of Friday, January 13, 1939, five inmates - William "Ty" Martin (AZ-370), Henri Young (AZ-244), Rufus McCain (AZ-267), Dale Stamphill (AZ-435), and Arthur "Doc" Barker (AZ-268) - broke out of their D-Block cells and climbed out of a window that had its bars severed in advance, with the sabotage camouflaged with paint and putty. The five men made it to the water's edge and began to look for driftwood to build a raft. In the meantime, their absence was discovered and guards swarmed the island with rifles and machine guns. Dark figures were spotted on the western shore and guards opened fire. Stamphill was shot in the legs multiple times but recovered. Doc Barker was hit in the head and died several hours later. The remaining three inmates gave up immediately and were recaptured without injury. The beach was later named after Doc Barker by the National Park Service.

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 Social Hall, also known as the Officers' Club, was a social club located on the northwestern side of the island of Alcatraz, off the coast of San Francisco, USA. Located in close proximity to the Power House, water tower and Former Military Chapel (Bachelor Quarters), it formerly housed the post exchange. The club was a social venue for the Federal Penitentiary workers and their families on the island to unwind after a hard week's work dealing with America's most hardened criminals after they'd been locked up at 17:30. It was burned down by a fire of disputed origins during the Occupation of Alcatraz in 1970; leaving a shell which still remains.

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.
