This week, Parisians woke up to what looked like a rocky mountain range rising above the River Seine.
The work of artist JR, the inflatable art installation transformed the city’s oldest bridge, the Pont Neuf, into a cave-like structure.
Parisian Alice Faure said: "At first, I was disappointed, but now I find it very beautiful because he manages to create movement with something mineral, to give it volume."
"La Caverne du Pont Neuf" is achieved with printed fabric and air creating craggy, limestone-like formations that tower above the bridge. From a distance, the installation appears like geology reclaiming the landmark.
JR is known for large-scale visual illusions across Paris landmarks, including a 2021 optical illusion that made it look as if the Eiffel Tower was perched precariously over a rocky ravine.
The temporary installation was privately funded and is free to the public. It opens on June 6 and will remain in place until June 28. Visitors will be able to walk through it once it opens.
