How JR Transformed Paris’s Oldest Bridge Into a Massive Grotto

French artist JR has transformed Paris's Pont Neuf, the city's oldest bridge, into a massive inflatable grotto titled *La Caverne du Pont Neuf* (2026). The installation measures 120 meters long, 20 meters wide, and up to 18 meters tall, and will be open to the public from June 6 to June 28. It incorporates sound design by Thomas Bangalter of Daft Punk, augmented reality via Snap Inc., and a Bloomberg Connect guide. Over 800 people helped realize the project, which was fabricated from 18,900 square meters of fabric and 20,000 cubic meters of pressurized air by French firm Air Toiles Concept. The work concludes a five-year series of large-scale trompe l'oeil pieces by JR and pays homage to Christo and Jeanne-Claude's *The Pont Neuf Wrapped, Paris* (1975–85), with the blessing of their foundation.

French artist JR has begun installing a monumental trompe-l’oeil work titled *La Caverne du Pont Neuf* (2026) on Paris’s Pont Neuf, transforming the city’s oldest bridge into an immersive cave. The project reimagines the bridge as a limestone quarry cave, referencing the stone from which the bridge and many Parisian buildings were constructed. The work pays homage to Christo and Jeanne-Claude’s iconic *The Pont Neuf Wrapped* (1985) and will be visible both day and night throughout the summer.

French artist JR has transformed the Pont-Neuf in Paris into a massive immersive cave installation titled "La Caverne du Pont-Neuf," unveiled in May 2026. The work pays homage to Christo and Jeanne-Claude's 1985 wrapping of the same bridge, using an inflatable double-wall structure covered with printed fabric to simulate rock formations and a prehistoric cave. The 120-meter-long installation is free and open to the public day and night, featuring augmented reality experiences via mobile devices and VR glasses, with a soundscape by a former Daft Punk member. The project, budgeted at €10.9 million funded by private sources, marks the first time JR has invited the public inside one of his works.
