Headquarters to France's state radio, this imposing 1962 circular-shape building is more than 500 yards in circumference. It's said to have more floor space than any other building in France and features a 200-foot tower that overlooks the Seine. Radio France sponsors more than 100 concerts a year, including performances by its own Orchestre Philharmonique de Radio France and the Orchestre National de France. Though many of these concerts take place at venues throughout the city, several are held here, and some are free.
