The Y-12 National Security Complex is a United States Department of Energy National Nuclear Security Administration facility located in Oak Ridge, Tennessee, near the Oak Ridge National Laboratory. It was built as part of the Manhattan Project for the purpose of enriching uranium for the first atomic bombs. It is considered the birthplace of the atomic bomb. In the years after World War II, it has been operated as a manufacturing facility for nuclear weapons components and related defense purposes. Y-12 is managed and operated under contract by Consolidated Nuclear Security, LLC (CNS), which is composed of member companies Bechtel National Inc., Leidos Inc., Orbital ATK, Inc, and SOC LLC, with Booz Allen Hamilton Inc. as a teaming subcontractor. CNS also operates Pantex Plant in Texas.

The American Museum of Science and Energy (AMSE) is a science museum in Oak Ridge, Tennessee, designed to teach children and adults about energy, especially nuclear power, and to document the role Oak Ridge played in the Manhattan Project. The museum opened as the American Museum of Atomic Energy in 1949 in an old World War II cafeteria on Jefferson Circle. It moved to its second facility in 1975 and was renamed AMSE in 1978.

Solway is an unincorporated community in Knox County, Tennessee, United States. The United States Geographic Names System classifies Solway as a populated place. The area is located between Oak Ridge and Knoxville, just southeast of the Clinch River (Melton Hill Lake), which forms the Anderson County line. It lies on Oak Ridge Highway, also known as Tennessee State Route 62, just north of its intersection with Pellissippi Parkway. Beaver Creek flows through the area. In 1999, Solway was proposed by Knox County and Oak Ridge planning officials to be included in a 1,000 acre area inside of Oak Ridge's urban growth boundary, which would have allowed the community to be annexed into the municipal limits of the city of Oak Ridge. However, this was voted down shortly after its proposal.

The United Church, Chapel on the Hill in Oak Ridge, Tennessee was the city's main church during World War II. Dedicated on September 30, 1943, and completed late in October 1943, it was originally a multi-denominational chapel shared by Catholic, Protestant and Jewish congregations.

The Clinton Engineer Works (CEW) was the production installation of the Manhattan Project that during World War II produced the enriched uranium used in the 1945 bombing of Hiroshima, as well as the first examples of reactor-produced plutonium. It consisted of production facilities arranged at three major sites, various utilities including a power plant, and the town of Oak Ridge. It was in East Tennessee, about 18 miles (29 km) west of Knoxville, and was named after the town of Clinton, eight miles (13 km) to the north. The production facilities were mainly in Roane County, and the northern part of the site was in Anderson County. The Manhattan District Engineer, Kenneth Nichols, moved the Manhattan District headquarters from Manhattan to Oak Ridge in August 1943. During the war, Clinton's advanced research was managed for the government by the University of Chicago. Construction workers were housed in a community known as Happy Valley. Built by the Army Corps of Engineers in 1943, this temporary community housed 15,000 people. The township of Oak Ridge was established to house the production staff. The operating force peaked at 50,000 workers just after the end of the war. The construction labor force peaked at 75,000 and the combined employment peak was 80,000. The town was developed by the federal government as a segregated community; black residents lived only in an area known as Gamble Valley, in government-built "hutments" (one-room shacks) on the south side of what is now Tuskegee Drive.

Oak Ridge High School is the public high school for Oak Ridge, Tennessee, enrolling grades 9 through 12. It was established in 1943 to educate the children of Manhattan Project workers.

Oak Ridge Historic District (also known as Clinton Engineer Works Townsite) is a historic district in Oak Ridge, Tennessee, that is listed on the National Register of Historic Places. Roughly bounded by East Drive, Outer and West Outer Drives, Louisiana Avenue, and Tennessee Avenue, the district comprises much of Oak Ridge's original Manhattan Project townsite, laid out by Skidmore, Owings and Merrill. Contributing properties in the historic district include United Church, The Chapel on the Hill, the Alexander Inn, and Highland View Elementary School, which houses the Children's Museum of Oak Ridge. The district was added to the National Register in 1991.

Oak Ridge is a city in Anderson and Roane counties in the eastern part of the U.S. state of Tennessee, about 25 miles (40 km) west of downtown Knoxville. Oak Ridge's population was 31,402 at the 2020 census. It is part of the Knoxville Metropolitan Area. Oak Ridge's nicknames include the Atomic City, the Secret City, the Ridge, the Town the Atomic Bomb Built, and the City Behind the Fence.In 1942, the United States federal government purchased nearly 60,000 acres (240 km2) of farmland in the Clinch River Valley for the development of a planned city supporting 75,000 residents. It was constructed with assistance from architectural and engineering firm Skidmore, Owings & Merrill, from 1942 to 1943. Oak Ridge was established in 1942 as a production site for the Manhattan Project—the massive American, British, and Canadian operation that developed the atomic bomb. Being the site of Oak Ridge National Laboratory and Y-12 National Security Complex, scientific and technological development still plays a crucial role in the city's economy and culture in general.

The Luther Brannon House was a stone bungalow structure at 151 Oak Ridge Turnpike in Oak Ridge, Tennessee, United States, where it was one of the few buildings remaining from before World War II. The house was built in 1941 by Owen Hackworth and just months later was acquired by the U.S. Army for the Manhattan Project. It was one of about 180 existing structures that were spared from demolition after the area was acquired for Manhattan Project production activities. The house is believed to have been used as headquarters for local project operations and living quarters for General Leslie Groves until the Army completed construction of new administration buildings.After the war, when most other remaining pre-war structures in Oak Ridge were torn down, the house was left standing. As of 1991, it was one of only three pre-World War II houses remaining in Oak Ridge, the others being Freels Cabin and the J. B. Jones House. It was listed on the National Register of Historic Places due to its association with General Groves and the early development of Oak Ridge.The house suffered significant damage from a fire in July 2014. As of April 2020, the fire damage still had not been repaired, and the property was listed for sale. As of February 2021, the house has been demolished, and was removed from the National Register in October, 2021

The J. B. Jones House in Oak Ridge, Tennessee, United States, is a farmhouse that is listed on the National Register of Historic Places as one of the very small number of pre-Manhattan Project residences remaining in the city.The house is on Old Edgemoor Road near Haw Ridge Park, across the Clinch River from the TVA Bull Run Steam Plant. It is a rectangular frame bungalow structure of one-and-one-half stories, built around 1920. It has a brick foundation, an asphalt-shingled roof, and weatherboard siding. The Jones House was one of 180 pre-World War II houses in Oak Ridge that were used by the U.S. Army during the Manhattan Project. Almost all of these houses were razed in the late 1940s; the Jones House, the Luther Brannon House, and Freels Cabin were the only survivors. The Anderson County Board of Education bought the Jones House from the U.S. Atomic Energy Commission in 1956, when Oak Ridge property first became available for sale. The building and grounds have subsequently been used for a variety of civic purposes. It was listed on the National Register in 1991.

Robertsville was a farming community in Anderson County, Tennessee, that was disbanded in 1942 when the area was acquired for the Manhattan Project. Its site is now part of the city of Oak Ridge, Tennessee. Robertsville was established in 1804 by a merchant named Collins Roberts, who received a 4,000-acre (16 km2) land grant. The community was located on the Old Emory Coach Road, and a natural spring in Robertsville called Cross Spring was a rest stop where travelers on that road could water and rest their horses. During the 19th century, Robertsville was also the site of a slave block. During the Civil War, however, community residents generally supported the Union cause.Notable residents included Swiss-German immigrant Henry Sienknecht, a Confederate Army physician who practiced medicine in Robertsville for several decades after the Civil War, before moving in 1890 to Oliver Springs, where he operated a store.The community continued to exist until 1942, when the United States government acquired the land as a part of the Manhattan Project. The residents of Robertsville were displaced, along with the residents of several other communities. Robertsville is now in the residential and commercial portion of the city of Oak Ridge. The present Robertsville Middle School is located on the site of the old Robertsville High School, which was built in about 1915. The high school gymnasium was retained to become the middle school's gym. Collins Roberts is buried in the Robertsville Baptist Cemetery. In the 1930s Cross Spring was dammed by a local farmer to form a small lake that the Army Corps of Engineers lined with concrete during World War II to convert it to a large swimming pool. The site of the lake is still the location of Oak Ridge's unusually large outdoor municipal swimming pool.
