Description

Perched above the Rhône, Fort l'Ecluse dominates the skyline. Dating back 700 years, it has many stories to tell. Come and discover them during self-guided or guided tours, through the fascinating scenography of the exhibition ‘Au cœur de la Cluse’ (At the heart of the Cluse) and the spectacular sound and light show "Fort l'Ecluse: 20,000 years of history ". There's something for everyone!
Thanks to its immersive exhibitions, dive into ‘Au cœur de l'orage’ (In the heart of the storm) and set off to ‘discover the lesser horseshoe bats’, the Fort's bats, and explore the temporary exhibition ‘Intuitions croisées’ (Crossed intuitions).
The summer events will thrill you: the 13th edition of the Jazz in Fort l'Ecluse festival, classical concerts by the Soloist Academy, Nuit des étoiles (Night of the Stars), and more.
And for those who want to get active, there are sporting activities: an adventure course with breathtaking views at the Upper Fort, a free-access via ferrata and hikes. Not to mention the challenge of obtaining the famous staircase diploma: climbing the 830 steps of the underground gallery that connects the Lower Fort to the Upper Fort.
