JR transforms the Pont-Neuf in Paris into La Caverne du Pont-Neuf, a giant cave installation that pays homage to Christo and Jeanne-Claude’s The Pont-Neuf Wrapped from forty years ago.

The project is funded by JR’s art sales and corporate sponsors, with about 800 people involved, including 25 Brittany artisans who hand-stitched the fabric.

The installation measures roughly 120 meters long, 18 meters high, and 20 meters wide, envisioned as the world’s largest immersive artwork and a walk-through structure.

The cave’s fabric is designed for reuse or recycling after the display, and weeks of testing at Orly airport ensured structural stability.

Access to the installation from Île de la Cité and the right-bank quays was planned for the weeks leading up to the opening.

Work began in early May with cranes and structural elements, and the project is slated to run from early June to late June, disrupting traffic and pedestrian flow.

On-site work is led by restoration and construction teams like Tollis, drawing public attention and praise from a local architect for the technical execution.

The project faced weather delays and underwent a rehearsal in an Orly hangar before a night installation ahead of its June 6–28 public window.

Visitors will traverse a long, dark tunnel with no daylight, as the bridge’s traffic is temporarily closed to vehicles; the installation will be visible from the river, quays, and the Eiffel Tower.

The experience is designed to be experienced on foot through the cave-like passage, offering a time-disoriented journey while remaining freely accessible to the public from June 6 to June 28.

Funded by JR’s artwork sales and corporate partners, the piece is free to the public and will block road traffic during its run while inviting pedestrians to walk through the air-filled installation.

The structure uses 20,000 cubic meters of air to form about 19,000 square meters of fabric, creating 80 air-filled arches that mimic massive rocks for visitors to walk through.
