Cabot Science Library

The Harvard University Science Center is Harvard's main classroom and laboratory building for undergraduate science and mathematics, in addition to housing numerous other facilities and services. Located just north of Harvard Yard, the Science Center was built in 1972 and opened in 1973 after a design by Josep Lluís Sert (then dean of the Harvard Graduate School of Design).

Harvard University's Collection of Historical Scientific Instruments (CHSI), established 1948, is "one of the three largest university collections of its kind in the world". Waywiser, the online catalog of the collection, lists over 60% of the collection's 20,000 objects as of 2014. The collection was originally curated by Mr. David P Wheatland in his office to prevent obsolete equipment from being cannibalized for its component parts and materials.A selection of instruments and artifacts from the collection is on permanent display in the Putnam Gallery on the first floor of the Harvard Science Center, which is free and open to the public on weekdays. In addition, rotating temporary exhibitions drawn from the collection are shown in the Special Exhibitions Gallery on the second floor, and a more modest Foyer Gallery space on the third floor.The CHSI includes a number of scientific instruments and demonstration apparatus purchased circa 1765 under the advice of Benjamin Franklin, to replace original equipment which had been lost in a disastrous fire which also destroyed the university's library in the original Harvard Hall. A number of items on display in the Putnam Gallery are labeled as originally having been specified by Franklin. One of the larger items in the collection is the Harvard Mark I, a historic room-sized electromechanical computer commissioned in 1944, which was exhibited next to the central stairwell in the main lobby of the Science Center, and has since been moved to the Harvard John A. Paulson School of Engineering and Applied Sciences. The collection continues to be expanded, under the supervision of a Director and several curators and technicians. Originally a part of the Harvard Library system, the CHSI is now affiliated with the Harvard Department of the History of Science, and is one of the four Harvard Museums of Science and Culture. The CHSI is also affiliated with the American Alliance of Museums.A strategic plan has been developed to expand the CHSI's missions of preservation, education, research, and display, including expanded educational outreach and higher-profile public exhibitions.

Bradstreet Gate, on the perimeter of Harvard Yard in Cambridge, Massachusetts, is a wrought-iron gate opposite Memorial Hall.

Memorial Hall, immediately north of Harvard Yard in Cambridge, Massachusetts, is an imposing High Victorian Gothic building honoring Harvard men's sacrifices in defense of the Union during the American Civil War‍—‌"a symbol of Boston's commitment to the Unionist cause and the abolitionist movement in America."Built on a former playing field known as the Delta, it was described by Henry James as consisting of three main divisions: one of them a theater, for academic ceremonies; another a vast refectory, covered with a timbered roof, hung about with portraits and lighted by stained windows, like the halls of the colleges of Oxford; and the third, the most interesting, a chamber high, dim and severe, consecrated to the sons of the university who fell in the long Civil War. James's "three divisions" are known today as (respectively) Sanders Theatre; Annenberg Hall (formerly Alumni Hall or the Great Hall); and Memorial Transept. Beneath Annenberg Hall, Loker Commons offers a number of student facilities.

The Lyman Laboratory of Physics (named for the physicist Theodore Lyman) is a building at Harvard University located between the Jefferson and Cruft Laboratories in the North Yard. It was built in the early 1930s, to a design by Coolidge, Shepley, Bulfinch and Abbott.Among those who have done research at Lyman are Sheldon Glashow, Higgins Professor of Physics, Emeritus and Richard Wilson, Mallinckrodt Professor of Physics, Emeritus. Here, Ranga Dias (Post-Doctoral Fellow) and Isaac F. Silvera (Thomas D. Cabot Professor of the Natural Sciences) claim to have gathered experimental evidence that solid metallic hydrogen had been synthesised.
