McDonough Gymnasium, sometimes referred to as McDonough Arena when hosting a sports or entertainment event, is a multi-purpose arena on the campus of Georgetown University in Washington, D.C. Officially known as McDonough Memorial Gymnasium, it opened in 1951 and can hold 2,200 spectators for sports events. One source claims that "McDonough Gymnasium" refers to the building as a whole, while "McDonough Arena" refers only to the event space within the building where athletic and social events take place.
