The Quad
The Quad is the nickname for the open plaza on the southern end of Barnard's campus. It is also Barnard's official designation for the grouping of the first-year residence halls (Hewitt Hall, Reid Hall, Sulzberger Tower, and Brooks Hall).
This is not to be confused with Van Am Quad, which is on Columbia's campus and called Van Am for short. Nobody ever calls Van Am the Quad. Ever.
