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!

Every year, the Heritage Days invite the curious to uncover hidden treasures tucked away in the corners and nooks of Paris and Île-de-France. This major cultural event opens the doors to museums, monuments, ministries, places of worship, artists’ studios, and stunning gardens. There isn’t enough of a weekend to see it all!

You can pull out your calendar now and book your visit slot to explore La Défense, on the outskirts of Paris.
