For this 40th edition of the Journées du Patrimoine, come and discover the fascinating Palais d'Iéna in Paris, headquarters of the Economic, Social and Environmental Council (CESE).

Built from 1937 to 1946 by Auguste Perret, the Palais d'Iéna opened its doors in 1939 as a Public Works Museum. Then, from 1956 to 1958, it became the headquarters of the Assembly of the French Union. Since 1959, it has housed the Conseil économique, social et environnemental, the Republic's third constitutional assembly. This work by Auguste Perret is remarkable for the vastness of its spaces and the quality of the materials used, particularly concrete.

On September 16 and 17, come and discover the Palais d'Iéna, as well as the workings and challenges of this republican institution.
