The heart of Harvard Square is the junction of Massachusetts Avenue and Brattle Street. Massachusetts Avenue enters from the southeast (a few miles after crossing the Charles River from Boston at MIT), and turns sharply to the north at the intersection, which is dominated by a large pedestrian space incorporating the MBTA subway entrance, an international newsstand, a visitor information kiosk, and a small open-air performance space ("The Pit"). Brattle Street and John F. Kennedy Street merge from the southwest, joining Massachusetts Avenue at "Nini's Corner", where another newsstand used to be located. The Harvard/MIT Cooperative Society main building forms the western streetwall at the intersection, along with a bank and some retail shops
