Memorial Amphitheater is an outdoor amphitheater, exhibit hall, and nonsectarian chapel located in Arlington National Cemetery in Arlington County, Virginia, in the United States. It was designed in 1913 as a replacement for the older, wooden amphitheater near Arlington House. Ground was broken for its construction in March 1915 and it was dedicated in May 1920. In the center of its eastern steps is the Tomb of the Unknown Soldier, dedicated in 1921. It has served as the site for numerous Veterans Day and Memorial Day events, as well as for memorial services and funerals for many individuals.
