Harvard Yard, in Cambridge, Massachusetts, is the oldest part of the Harvard University campus, its historic center and modern crossroads. It contains most of the freshman dormitories, Harvard's most important libraries, Memorial Church, several classroom and departmental buildings, and the offices of senior University officials including the President of Harvard University. The Yard grew over the centuries around Harvard College's first parcel of land, purchased in 1637. Today it is a grassy area of bounded principally by Massachusetts Avenue, Cambridge Street, Broadway, and Quincy Street. Its perimeter fencingprincipally iron, with some stretches of brickhas twenty-seven gates. Subdivisions The center of the Yard, known as Tercentenary Theatre, is a wide grassy area bounded by Widener Library, Memorial Church, University Hall, and Sever Hall. Tercentenary Theatre is the site of annual commencement exercises and other convocations. The western third of Harvard Yard, which opens onto Peabody Street (often mistaken for nearby Massachusetts Avenue) at Johnston Gate and abuts the center of Harvard Square to the south, is known as the Old Yard. Most of the freshman dormitories cluster around the Old Yard, including Massachusetts Hall (1720), Harvard's oldest building and the second-oldest academic building in the United States. Massachusetts Hall also houses the offices of the President of Harvard University. The original Harvard Hall in the Old Yard housed the College library, including the books donated by John Harvardall but one of which were destroyed when the building burned in 1764. Rebuilt in 1766, the current Harvard Hall now houses classrooms. Across the Old Yard from Johnston Gate is University Hall (1815), whose white-granite facade was the first to challenge the red-brick Georgian style until then ascendant; between its twin west staircases stands the John Harvard statue. University Hall contains major administrative offices, including those of the Dean of the Faculty of Arts and Sciences and the Dean of Harvard College. Buildings Libraries in the Yard are Widener Library, its connected Pusey Library annex, Houghton Library for rare books and manuscripts, and Lamont Library, the main undergraduate library. Classroom and departmental buildings include Emerson Hall, Sever Hall, Robinson Hall, and Boylston Hall. The Harvard Bixi, a Chinese stele with inscribed text, is located near Widener.
