The Rosedale Arch is dedicated to the men of Rosedale, a neighborhood district and former municipality on the southern edge of Kansas City, Kansas, who served in World War I. Inspired by the Arc de Triomphe, the Arch was designed by John LeRoy Marshall, a Rosedale resident, and dedicated in 1924. Located on Mount Marty, the flood-lighted arch is most easily visible at night from the intersection of Rainbow Boulevard and Southwest Boulevard. A historic marker was dedicated under the arch in 1993 to honor the soldiers of World War II, Korean War, and Vietnam War.
