Washington, D.C. residents built a Peristyle Doric Temple to memorialize local heroes who served the nation in World War One. Completed in 1931, the temple is located on the National Mall in West Potomac Park in Washington, D.C. It was the first memorial on the Mall to list all D.C. residents who lost their lives in the war, regardless of their race, class, or gender. The D.C. War Memorial is the only local D.C. memorial on the National Mall. It was entrusted to the U.S. National Park Service. The memorial is forty feet in diameter and large enough to hold the 80-member U.S. Marine Corps Band.
