Nicknamed the three-pointed star for its unique ‘Y’shaped design, the UNESO HQ [7 Place de Fontenoy +33 145681000 http://www.unesco.org/] in Paris, is more than just the home of a world-famous organization. Known for its unique architecture, the UNESCO main building is accompanied by three other structures, all housing internally acclaimed works of art. The main highlight though is the free-access museum in the main building which features a top-notch international collection.
