JR’s Pont-Neuf cave
In Paris, the artist JR is transforming the Pont-Neuf, described as the oldest bridge in the French capital, into an inflatable immersive installation called La Caverne du Pont-Neuf.
“JR transforms Pont Neuf: a monumental cavern between past and present In 1607, the Pont Neuf was completed”
The installation is scheduled to be accessible for free from 6 to 28 June, and it is presented as « la plus grande œuvre immersive au monde ».
JR anchors the project in Plato’s allegory of the cave, and he links the cave’s shadows to smartphone screens, saying: « Aujourd'hui, nos
ombres
ce sont nos téléphones, nos bulles d'algorithmes qui nous enferment chacun dans une version différente du monde et nous polarisent ».
The structure is described as 120 meters long, 20 meters wide, and up to 18 meters high, covering 2 400 m² of ground area and using 18 900 m² of textile with a total weight of five tonnes.
The Pont-Neuf is said to be « aucunement altéré », and the double-wall inflatable structure is composed of 80 arches in printed canvas, continuously powered by 20 000 m³ of air.
Sound, AR, and makers
Inside La Caverne du Pont-Neuf, visitors encounter a sound creation by the ex-Datf Punk Thomas Bangalter, presented as part of JR’s collaboration for Retour à la Caverne at the Palais Garnier.
JR also works with AR Studio Paris of Snap on a reality-augmented route called Echoes, described as inspired by Étienne-Jules Marey’s chronophotography research that decomposes movement on a single image.
The installation’s inflatable structure is tied to a Breton production effort, with fabrication entrusted to Air Toiles Concept, a PME bretonne based in Plougoumelen in the Morbihan.
Le Journal Des Arts says Air Toiles Concept mobilized 30 people for the chantier, and that at total 800 people participated in the realization of La Caverne du Pont-Neuf.
A first inflation test took place in the night of 20 to 21 May in just over an hour, after other tests were conducted earlier in a hangar at Orly and a 15-meter model was assembled in January.
Christo link and timeline
La Caverne du Pont-Neuf is explicitly framed as a homage to Christo and Jeanne-Claude’s Pont-Neuf wrapping, which the sources place from 22 September to 5 October 1985.
“Subscriber-only article”
Le Journal Des Arts recalls that the 1985 empaquetage mobilized 41 800 m² of fabric, 13 km of cordes, and 12 tonnes de câbles d'acier, with 300 ouvriers and a dozen engineers.
The installation is set to be dismantled after its run, and the local coverage says it will be open from June 6 to June 28, 2026, with access described as 24/7 and free.
Ville de Paris also specifies that the cave was set up on the night of May 21, and it describes the exterior as an inflatable structure filled by air through 80 structural fabric arches.
In the same account, JR describes the crossing as « un voyage vers l’ignoto et dedans soi », while the sound dimension is again attributed to Thomas Bangalter, who is described as envisioning « sculpting a sonic material from electroacoustic elements ».
