In celebration of the centennial of George Washington's inauguration in 1889, a temporary wood and plaster arch was erected at Washington Square. Six years later it was replaced by the present seventy-seven-foot marble structure. In 1916 another celebration of sorts was held. A group of artists led by John Sloan and Marcel Duchamp forced open the door to the stairs leading to the top of the arch and held a midwinter party to declare the secession of Greenwich Village from the United States of America. They lit Japanese lanterns, read poems, fired cap pistols, and proclaimed the independence of the state of New Bohemia.
