Phare du Monde ("Lighthouse of the world") was an observation tower planned for the
1937 World Fair in Paris, France. The Phare du Monde, advertised as a "Pleasure Tower Half Mile High"[1] was designed by Eugène Freyssinet, and was to be a 701-metre (2,300 feet) tall concrete tower with a light beacon and a restaurant on the top. A spiralling road on the outside of the tower shaft was to be built for driving access to a height of 1,640 feet (500 m), to a parking garage for 500 cars.[2] This focus on the car in such an eye-catching construction has been seen as proof of the car (by 1939) having become "the primary force in determining the appearance of the ordinary landscape of cities."[3] The costs were estimated to have been $2.5 million;[4] it was never built.
