Uline Arena, renamed the Washington Coliseum, is an indoor arena in Washington, D.C. located on Third Street, NE, directly adjacent to the railroad tracks just north of Union Station and bounded by L and M Streets. It held 7,000 to 9,000 people for events. It hosted the Basketball Association of America's Washington Capitols, coached by Red Auerbach, and the American Basketball Association's Washington Caps. It was also the site of the very first concert by The Beatles in the United States.
