The Arch commemorates the centennial of George Washington's 1789 inauguration as President of the United States, and forms the southern terminus of Fifth Avenue. Washington Arch, constructed of white Tuckahoe marble, was conceived by Stanford White, who imitated a Roman triumphal arch, namely the Arch of Titus, iconic monuments which Roman emperors built throughout the empire to celebrate a victory or event. The iconography of the Arch centers on images of war and peace. On the frieze are 13 large stars and 42 small stars, interspersed with capital "W"s. The spandrels contain figures of Victory. MacNeil was the artist for Washington as commander in chief; Calder sculpted Washington as civilian.
