Arlington Memorial Amphitheater, Washington D.C.

Memorial Amphitheater in Arlington National Cemetery replaced an older wooden amphitheater in 1913. It now serves as an open-air venue with an amphitheater, exhibition hall, and chapel. It's located amidst various monuments and landscape elements, like the USS Maine Mast Memorial to the west, the Spanish–American War Memorial to the south, and a formal Italian-style garden to the east.

On October 13, 1915, President Woodrow Wilson laid the cornerstone for a new amphitheater, which held a copper box with 15 significant items, such as the US Constitution, Declaration of Independence, Bible, American flag, coins, stamps, Congressional directory, DC telephone book, President Wilson's photo, and Arlington National Cemetery mementos.

The amphitheater itself was predominantly constructed using Imperial Danby marble sourced from Vermont and Botticino stone imported from Italy. It was officially dedicated on May 15, 1920, and underwent several renovations throughout the years, including those in 1956, 1974, 1995–1996, and 2012.

This venue hosts regular memorial services, including those on Memorial Day and Veterans Day, sponsored by the U.S. Army Military District of Washington. These events often feature the President or Vice President. Since 1931, it's been the site of the popular annual Easter sunrise service, initially organized by the Knights Templar and attended by President Herbert Hoover. Additionally, many military organizations hold annual memorial services here, with nearly 5,000 attendees each year.

Memorial Amphitheater hosts state funerals for distinguished Americans, including General John J. "Black Jack" Pershing, Secretary of Defense James Forrestal, and Rear Admiral Richard E. Byrd. It's also the resting place for an unknown Vietnam War soldier (1984), 30 unidentified 9/11 Pentagon attack victims (2002), and the last WWI American veteran (2011).
