The U.S. National World War II Memorial is a National Memorial dedicated to Americans who served in the armed forces and as civilians during World War II. Consisting of 56 pillars and a pair of small triumphal arches surrounding a plaza and fountain, it is located on the National Mall in Washington, D.C., on the former site of the Rainbow Pool at the eastern end of the Reflecting Pool, between the Lincoln Memorial and the Washington Monument.
It opened to the public on April 29, 2004, and was dedicated by President George W. Bush on May 29, 2004, two days before Memorial Day. The memorial is administered by the National Park Service under its National Mall and Memorial Parks group. As of 2009, more than 4.4 million people visit the memorial each year.
