JR’s inflatable cave across the pont neuf is now open in paris
step inside la caverne du pont neuf
Along the Seine in central Paris, JR‘s La Caverne du Pont Neuf has opened after a weather-delayed start earlier this month. The installation now covers Paris’ oldest bridge with a rocky, cavernous skin, turning the familiar stone crossing into a temporary passage shaped by fabric, air, sound, scent, and augmented reality.
The project opened to the public on June 15th will remain accessible until June 28th from Place du Pont Neuf Christo et Jeanne-Claude. Conceived as JR’s homage to Christo and Jeanne-Claude’s 1985 work The Pont Neuf Wrapped, the installation is free to enter, open twenty-four hours a day, and visible from the quays, nearby bridges, passing boats, and the upper banks of the Seine.

a temporary cave over paris’ oldest bridge
Across the bridge, La Caverne du Pont Neuf draws from the quarries that supplied the limestone used in Paris’ historic architecture. Completed in 1607, the Pont Neuf was the city’s first bridge built entirely of Lutetian limestone, and JR’s intervention turns that material history inside out, wrapping the structure in an image of its own geological origin.
The installation’s opening was delayed after strong wind gusts and hail struck on June 2nd, tearing sections of the inflatable envelope while work was still underway. Artist JR and his team repaired the damage in public view, then chose to accentuate the repair seams in black, leaving the incident visible as part of the work’s short life on the bridge.

air becomes the main structure
La Caverne du Pont Neuf covers 2,400 square meters and stretches 120 meters long by 20 meters wide, with high points ranging from 12 to 18 meters. Its form relies on a double-walled inflatable structure with permanent ventilation, using slightly pressurized air to fill 80 structural canvas arches beneath printed fabric.
The technical system brings together an external supporting structure, an inner printed tunnel held by suction, and an outer printed envelope that drops toward the base of the bridge piers. In total, the installation uses 18,900 square meters of fabric and 20,000 cubic meters of air, while ballast is limited to 130 tons distributed across the bridge.

inside the crossing
Within the inflated volume, visitors pass through a fabric tunnel that gives the bridge a second interior. The lightweight material, weighing 160 grams per square meter, is sewn into shaped surfaces and held in place by suction, allowing the space to float within the larger structure while metal gantries support safety requirements.
Sound adds another layer to the crossing through a collaboration with Thomas Bangalter, formerly of Daft Punk, who composed an electroacoustic atmosphere for the installation. His contribution works as a mineral-like texture around the body, shaping the experience through resonance instead of a conventional musical score.

augmented reality and scent shape the route
JR also worked with Snap Inc.’s AR Studio Paris on Echoes, an augmented reality experience available on mobile devices and through Spectacles. Inspired by Étienne-Jules Marey’s chronophotography, the digital layer introduces moving traces of bodies, animals, light, and sound around the bridge, allowing visitors to activate another reading of the work as they cross.
For the first time in JR’s practice, scent becomes part of the installation as well. Developed with Sarah Bouasse and fragrance house Odore Scola, two accords are diffused through different areas of La Caverne, adding an atmospheric layer that relates to geology, origins, and the air moving through the structure.

after the bridge
Alongside the Pont Neuf installation, JR is presenting Les esquisses de La Caverne at Galerie Perrotin’s Marais space through July 25th. The exhibition brings together preparatory works made through photography, drawing, collage, and crumpled zinc sheets salvaged from Parisian rooftops, extending the project’s material research into the gallery.
La Caverne du Pont Neuf arrives four decades after Christo and Jeanne-Claude wrapped the same bridge, yet its temporary architecture speaks to a different set of conditions. Air, printed fabric, repair seams, digital overlays, and scent turn the crossing into a layered encounter with Paris, where the city’s stone history and the fragile mechanics of temporary construction meet above the Seine.
