Angel Island is an island in San Francisco Bay. The entire island is included within Angel Island State Park, administered by California State Parks. The island, a California Historical Landmark, has been used by humans for a variety of purposes, including seasonal hunting and gathering by indigenous peoples, water and timber supply for European ships, ranching by Mexicans, United States military installations, a United States Public Health Service Quarantine Station, and a U.S. Bureau of Immigration inspection and detention facility. The Angel Island Immigration Station, on the northeast corner of the island, which has been designated a National Historic Landmark, was where officials detained, inspected, and examined approximately one million immigrants, who primarily came from Asia. Under the Chinese Exclusion Act of 1882, the first United States law to restrict a group of immigrants based on their race, nationality, and class, all arriving Chinese immigrants were to be examined by immigration or customs agents.

Angel Island Immigration Station was an immigration station in San Francisco Bay which operated from January 21, 1910, to November 5, 1940, where immigrants entering the United States were detained and interrogated. Angel Island is an island in San Francisco Bay. It is currently a State Park administered by California State Parks and a California Historical Landmark. The island was originally a fishing and hunting site for Coastal Miwok Indians, then it was a haven for Spanish explorer Juan Manuel de Ayala. Later, it was developed as a cattle ranch, then, starting with the Civil War, the island served as a U.S. Army post. During the island's Immigration Station period, the island held hundreds of thousands of immigrants, the majority from China, Japan, India, Mexico and the Philippines. The detention facility was considered ideal because of its isolated location, making it very easy to control immigrants, contain outbreaks of disease, and enforce the new immigration laws. The station is listed on the National Register of Historic Places under the title Angel Island, U.S. Immigration Station, and is a National Historic Landmark. The station is open to the public as a museum – "a place for reflection and discovery of our shared history as a nation of immigrants".

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."

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 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.

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.

The New Industries Building is a building on the western end of Alcatraz Island off the coast of San Francisco, United States. It was constructed in 1939 for $186,000 as part of a $1.1 million modernization scheme which also included the water tower, power house, officers quarters and remodeling of the D-block.The ground floor of the two-story 306 ft long building contained a clothing factory, dry cleaning plant, furniture plant, brush factory, and an office, where prisoners of the federal penitentiary could work for money. They made items such as gloves, furniture mats, and army uniforms. The laundry room occupied the entire upper floor, the largest in San Francisco at the time. Each window has 9 panes and there are 17 bays on each floor on either side. In recent years the building has been updated to address the erosion of the concrete and rust had caused, strengthen the walls and floors, repairing the roof and adding weatherproofed windows and door openings. The Guard Tower on the top of the building was also renovated and remounted.

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.
