Arlington National Cemetary

Arlington National Cemetery, located in Arlington, Virginia, across the Potomac River from Washington, D.C., is one of the United States' most hallowed burial grounds. Established during the Civil War in 1864 on the estate of Confederate General Robert E. Lee, it spans approximately 639 acres and serves as the final resting place for over 400,000 military personnel, veterans, and their families. Notable sites within the cemetery include the Tomb of the Unknown Soldier, which is continuously guarded by the 3rd U.S. Infantry Regiment, and the graves of President John F. Kennedy, marked by an eternal flame, and President William Howard Taft. The cemetery is also home to numerous memorials, such as the Space Shuttle Challenger Memorial and the USS Maine Mast Memorial. Managed by the U.S. Army, Arlington hosts annual ceremonies on Memorial Day and other significant events, drawing millions of visitors each year who come to honor the service and sacrifice of America's armed forces.
