Which neoclassical arch in New York City is located in Washington Square Park?

The neoclassical arch in New York City located in Washington Square Park is the Washington Square Arch. Officially called the Washington Arch, it marks the southern end of Fifth Avenue in Greenwich Village, Manhattan.

Architect Stanford White designed the permanent marble arch in 1891–1892 to commemorate the centennial of George Washington’s 1789 inauguration as president. It replaced a temporary plaster-and-wood arch erected in 1889, whose popularity persuaded New Yorkers to fund a lasting monument. The permanent structure was dedicated in 1895.

The arch is made of white Tuckahoe marble and rises 77 feet. Its form draws on Roman triumphal arches, especially the Arch of Titus. Sculptural additions on its north side, including figures of George Washington, were installed later. It is often associated with New York University because of its prominent position beside the university’s Washington Square campus.
