Currier House is one of twelve undergraduate residential Houses of Harvard College, in Cambridge, Massachusetts, United States. Opened in September 1970, it is named after Audrey Bruce Currier, a member of the Radcliffe College Class of 1956 who, along with her husband, was killed in a plane crash in 1967. The area was formerly used as housing for Radcliffe College, and as such the four towers of Currier House are named for distinguished alumnae of Radcliffe, including the author Barbara Tuchman. Along with Cabot House and Pforzheimer House, Currier is part of the former Radcliffe Quadrangle, known colloquially as simply "the Quad."

Pforzheimer House, nicknamed PfoHo (FOE-hoe) and formerly named North House, is one of twelve undergraduate residential Houses at Harvard University.

The Radcliffe Quadrangle at Harvard University, formerly the residential campus of Radcliffe College, is part of Harvard's undergraduate campus in Cambridge, Massachusetts, United States. Nicknamed the Quad, it is a traditional college quad slightly removed from the main part of campus.

Cabot House is one of twelve undergraduate residential Houses at Harvard University. Cabot House derives from the merger in 1970 of Radcliffe College's South and East House, which took the name South House (also known as "SoHo"), until the name was changed and the House reincorporated in 1984 to honor Harvard benefactors Thomas Cabot and Virginia Cabot. The house is composed of six buildings surrounding Radcliffe Quadrangle; in order of construction, they are Bertram Hall (1901), Eliot Hall (1906), Whitman Hall (1911), Barnard Hall (1912), Briggs Hall (1923), and Cabot Hall (1937). All six of these structures were originally women-only Radcliffe College dormitories until they were integrated in 1970. Along with Currier House and Pforzheimer House, Cabot is part of the Radcliffe Quad. The current Faculty Deans of Cabot House are Ian Miller and Crate Herbert. Prior Masters include then-Radcliffe President Mary Bunting and New Republic publisher Martin Peretz.

The Gray Gardens East and West Historic District is a historic district encompassing an early 20th century residential subdivision in Cambridge, Massachusetts. The subdivision includes all of the properties on Gray Gardens (East and West), as well as the adjacent 91 Garden Street and 60 Raymond Street. The subdivision was created by a group of interested individuals who sought to control development of one of the last estates in the area to be developed. They subdivided the land themselves, and imposed architectural restrictions on what could be built. Most of the houses were built between 1922 and 1930 and are neo-Georgian in style; the principal exception is the Hall Tavern, a Federal style tavern built in the 1790s and moved to the area from Duxbury, Massachusetts. The other unusual house is at 16 Gray Gardens East; it is a Tudor Revival house.The district was listed on the National Register of Historic Places in 1986.

The Sears Tower—Harvard Observatory is a historic astronomical observatory that is part of Harvard Observatory and is located at 60 Garden Street in Cambridge, Massachusetts. Now just a portion of the observatory's Building A, the Sears Tower is the oldest portion of the complex, designed by Isaiah Rogers and constructed in 1843. This structure is a square brick building, with a projecting cornice and a Greek Revival entrance framed by pilasters. The dome was equipped with a 15-inch telescope, the state of the art at the time.The tower was listed on the National Register of Historic Places in 1987.

The Center for Astrophysics | Harvard & Smithsonian (CfA) is an astrophysics research institute jointly operated by the Harvard College Observatory and Smithsonian Astrophysical Observatory. Founded in 1973 and headquartered in Cambridge, Massachusetts, the CfA leads a broad program of research in astronomy, astrophysics, Earth and space sciences, as well as science education. The CfA either leads or participates in the development and operations of more than fifteen ground- and space-based astronomical research observatories across the electromagnetic spectrum, including the forthcoming Giant Magellan Telescope (GMT) and the Chandra X-ray Observatory, one of NASA's Great Observatories. Hosting more than 850 scientists, engineers, and support staff, the CfA is among the largest astronomical research institutes in the world. Its projects have included Nobel Prize-winning advances in cosmology and high energy astrophysics, the discovery of many exoplanets, and the first image of a black hole. The CfA also serves a major role in the global astrophysics research community: the CfA's Astrophysics Data System (ADS), for example, has been universally adopted as the world's online database of astronomy and physics papers. Known for most of its history as the "Harvard-Smithsonian Center for Astrophysics", the CfA rebranded in 2018 to its current name in an effort to reflect its unique status as a joint collaboration between Harvard University and the Smithsonian Institution. The CfA's current director (since 2004) is Charles R. Alcock, who succeeds Irwin I. Shapiro (Director from 1982 to 2004) and George B. Field (Director from 1973 to 1982).

The Smithsonian Astrophysical Observatory (SAO) is a research institute of the Smithsonian Institution, concentrating on astrophysical studies including galactic and extragalactic astronomy, cosmology, solar, earth and planetary sciences, theory and instrumentation, using observations at wavelengths from the highest energy gamma rays to the radio, along with gravitational waves. Established in Washington, D.C., in 1890, the SAO moved its headquarters in 1955 to Cambridge, Massachusetts, where its research is a collaboration with the Harvard College Observatory (HCO) and the Harvard University Department of Astronomy. In 1973, the Smithsonian and Harvard formalized the collaboration as the Center for Astrophysics | Harvard & Smithsonian (CfA) under a single Director.

The Harvard College Observatory (HCO) is an institution managing a complex of buildings and multiple instruments used for astronomical research by the Harvard University Department of Astronomy. It is located in Cambridge, Massachusetts, United States, and was founded in 1839. With the Smithsonian Astrophysical Observatory, it forms part of the Harvard–Smithsonian Center for Astrophysics. HCO houses a collection of approximately 500,000 astronomical plates taken between the mid-1880s and 1989 (with a gap from 1953–1968). This 100-year coverage is a unique resource for studying temporal variations in the universe. The Digital Access to a Sky Century @ Harvard project is digitally scanning and archiving these photographic plates.
