PARIS (AP) — He is known as the French Banksy — or simply JR. Now the artist popular across France for large-scale projects, from photographs to graffiti and street art, wants Parisians to do something unusual on the city’s arguably most famous bridge: stop.

In June, he plans to transform the bustling Pont Neuf that dates back to the 17th century into a walk-through “cave” — a temporary, monumental public artwork that will cover the stone arches with a rocky illusion and invite visitors to cross the River Seine through a tunnel, complete with sound and digitally augmented reality.

He says it’s possibly the “largest immersive installation ever made” and — one that will be accessible around the clock and offer a “totally different approach” to the bridge.

“We’re about to leave something pretty incredible in the middle of Paris,” JR told The Associated Press at his studio in eastern Paris, wearing his trademark hat and shades.

His project, the Pont Neuf Cavern is to run June 6-28, spanning 120 meters (yards) in length and over 17 meters in height.

To JR, the homage is both aesthetic and personal.

“I had the chance to meet Christo along the years,” he said. “We had big respect for each other’s work.”

While walking recently on the street with an AP crew, an older woman stopped JR — now, a household name in his country — to share her memories of the Christo and Jeanne-Claude wrapping. She told him she was excited to see the bridge transformed again.

Still, JR — a pseudonym stemming from first name, Jean-René — acknowledges the weight of following in the iconic pair’s footsteps.

“It’s pretty hard to go after them,” he said, “but I’m doing it in a very different style, in my own way.”

His idea is about “bringing back mineral and nature” to the heart of Paris.

Two experiences: the city, then the cave
JR said there will be two main ways for people to experience his installation. From the outside, those heading to Pont Neuf will see the giant installation hundreds of meters away.

And from the inside, once visitors enter the “cave” on Pont Neuf, they will be able to walk through a long tunnel-like structure, having a feeling of “total immersion,” he said.

The cave will allow no daylight in and once inside, visitors “will lose track of time,” JR said.

A key collaborator on the project is Thomas Bangalter, a former member of French rock band Daft Punk who is creating the sound to accompany the installation — “something you’ll only hear from the inside,” JR said.

Snap’s AR studio in Paris is developing the augmented reality technology. Visitors will be able to use their smartphones to “experience and see things that you can’t see with your eyes,” JR said.

He is intentionally mysterious about what that is — keeping it a surprise until closer to the opening.

JR said visitor numbers will be limited at any given time, and that his team is consulting with authorities on that. During the three weeks of the exhibition, the installation will be continuously monitored.

A cave, and a metaphor
JR is best known for his large-scale art — enormous portraits pasted on buildings, border walls and rooftops. Because of his origins in graffiti and street art he has inevitably drawn comparison with Banksy, the elusive U.K.-based artist famous for his huge murals and activism.

JR’s installation will not have any massive faces, but the theme is still human, he says: gathering, connection, and what people project onto a shared space.

“What are our caves today is our phone,” JR said, “because we … believe that … our algorithm on social media … is the reality.”

During the installation, which will coincide with June’s Paris Fashion Week and World Music Day, the bridge will close to traffic.
