A stroll through the glass towers of La Défense for the 2026 Heritage Days

The quartier de la Défense isn’t the most beloved corner of Paris and its nearby suburbs. The business district and its soaring towers stand in stark contrast to Haussmann-era Paris, which locals and visitors alike often favor. Yet La Défense is full of hidden gems and little-known stories that can be explored during special days...

Take part in the Journées du Patrimoine 2026, on Sunday, September 20, to explore the La Défense district. From the Grande Arche to the office towers, rediscover La Défense like you’ve never seen it before. This stroll might surprise you!

  Saviez-vous que coexistent pas moins de 5 générations de tours à La Défense ? Daneel Art vous amène à la découverte de chacune d’entre elles dans une visite guidée passionnante sur l’évolution de l’architecture du célèbre quartier d’affaires. Cette visite guidée aborde les générations successives de tours à La Défense, ainsi que les enjeux de construction à l’ère post-carbone, à travers notamment la réinvention du bâti existant et son adaptation aux nouvelles contraintes écologiques et économiques.
