Robert F. Kennedy Memorial Stadium, commonly known as RFK Stadium, is a multi-purpose stadium in Washington, D.C., located about two miles (3 km) due east of the U.S. Capitol building. The stadium opened as District of Columbia Stadium (often shortened to D.C. Stadium) in October 1961, and was constructed as a joint venture of the D.C. Armory Board and the U.S. Department of the Interior. From 1996 to 2017, D.C. United of Major League Soccer played its home matches at RFK Stadium prior to moving to Audi Field for 2018. The stadium was renamed in January 1969 for U.S. Senator and presidential candidate Robert F. Kennedy, who had been assassinated in Los Angeles the previous June. It has a listed capacity of about 46,000 for soccer games. Since the stadium is on a direct sight line with the Washington Monument and the U.S. Capitol, light towers were not allowed; instead, arc lights were placed on its curved, dipping roof.
