Paris opens a new public artwork transforming the Pont Neuf, the city’s oldest bridge, into an immersive “artificial cavern.” Multiple outlets report that the French street artist JR is behind the project, which presents monumental cave imagery and an environment designed for visitors to enter and experience. Coverage highlights that the installation extends beyond visuals, incorporating sensory elements associated with the cave theme. The reports describe the public stepping into the installation and “sniffing” as part of the experience, with one outlet emphasizing that scent helps complete the illusion. The bridge remains a historic landmark during the transformation, and the installation is presented as a final opening for public viewing rather than a closed or preparatory stage. While outlets differ in how they describe specific sensory details, they consistently identify JR as the creator, Pont Neuf as the location, and the work as an artificial cavern-style cave-art presentation that now allows direct public access.
