Harvard's 209-acre main campus is centered on Harvard Yard ("the Yard") in Cambridge, about 3 miles west-northwest of downtown Boston, and extends into the surrounding Harvard Square neighborhood. The Yard contains administrative offices such as University Hall and Massachusetts Hall; libraries such as Widener, Pusey, Houghton, and Lamont; and Memorial Church.
The Yard and adjacent areas include the main academic buildings of the Faculty of Arts and Sciences, including the college, such as Sever Hall and Harvard Hall.

Memorial Church
Freshman dormitories are in, or adjacent to, the Yard. Upperclassmen live in the twelve residential houses – nine south of the Yard near the Charles River, the others half a mile northwest of the Yard at the Radcliffe Quadrangle (which formerly housed Radcliffe College students). Each house is a community of undergraduates, faculty deans, and resident tutors, with its own dining hall, library, and recreational facilities.

Also in Cambridge are the Law, Divinity (theology), Engineering and Applied Science, Design (architecture), Education, Kennedy (public policy), and Extension schools, as well as the Radcliffe Institute for Advanced Study in Radcliffe Yard. Harvard also has commercial real estate holdings in Cambridge.
