Iwo Jima Memorial..The Iwo Jima Memorial, also known as the U. S. Marine Corps War Memorial, honors the Marines who have died defending the United States since 1775. The Iwo Jima Memorial is located near Arlington National Cemetery, in Arlington, Virginia, just across the Potomac River from Washington, DC. Very emotional place to visit..especially watching the Sunset Review Parade Tuesdays from 7 to 8:30 p.m., May through August.
