Gréber designed the Parkway in 1917 to emulate the Champs-Élysées in Paris, France. The route was determined by an axis drawn from City Hall Tower to a fixed point on the hill that William Penn called "Fairmount", now the site of the Philadelphia Museum of Art. The Champs-Élysées terminates at the Arc de Triomphe, and the Parkway's terminating at the Art Museum gives the notion of "a slice of Paris in Philadelphia." The Parkway contains flags of countries from around the world.
