The Van Wickle Gates, dedicated on June 18, 1901, have a pair of smaller side gates that are open year-round, and a large central gate that is opened two days a year for Convocation and Commencement. At Convocation the gate opens inward to admit the procession of new students. At Commencement the gate opens outward for the procession of graduates.  A Brown superstition is that students who walk through the central gate a second time prematurely will not graduate, although walking backwards is said to cancel the hex. Members of the Brown University Band famously flout the superstition by walking through the gate three times too many, as they annually play their role in the Commencement parade.
