JR Transforms Pont Neuf into a Subterranean Landscape, Honoring Christo's Legacy

Forty years after Christo and Jeanne-Claude's iconic 'The Pont Neuf Wrapped' redefined urban art, French artist JR is set to commemorate this legacy with his own ambitious project, 'La Caverne du Pont Neuf.' This new immersive installation will transform Paris's historic Pont Neuf into a grand, stone-like cavern that visitors can explore. Scheduled to be on display from June 6th to June 28th, 2026, JR's work not only pays homage to the past but also pushes the boundaries of temporary public art through innovative use of architecture, sound, and augmented reality, inviting a new generation to experience and interpret art in the urban landscape.

Christo and Jeanne-Claude's original 1985 endeavor involved encasing the Pont Neuf in 41,800 square meters of fabric, secured by miles of rope and steel cables. This monumental undertaking, which took a decade of meticulous planning and negotiation, was viewed by three million people during its two-week exhibition. Christo himself articulated the intention behind 'The Pont Neuf Wrapped,' stating his desire to elevate the bridge from a mere infrastructural element to an ephemeral sculpture, inviting individual interpretation and highlighting the transient nature of art. In a departure from physically wrapping the bridge, JR envisions the Pont Neuf as an inhabitable subterranean realm. His concept for 'La Caverne du Pont Neuf' offers a symbolic journey through a grotto-like interior, where the rough textures of natural geology merge with the refined aesthetics of Parisian architecture.

To create this striking illusion, JR’s 'Projet Pont Neuf' will employ a massive inflatable structure crafted from printed fabric and air-filled arches. This design meticulously re-creates the appearance of mineral formations, seemingly growing across the bridge. The inspiration for these geological features comes from the very limestone quarries that provided the building blocks for many of Paris's historic structures. JR's artistic approach, therefore, creates a dialogue between the city's sophisticated urban environment and the raw, untamed beauty of its natural origins, prompting contemplation on Paris's evolving relationship with both nature and built heritage.

JR expresses deep admiration for Christo and Jeanne-Claude's artistic philosophy, particularly their belief that art's purpose is to stimulate public thought. He emphasizes that the discussions and debates sparked by a monumental public art project are as valuable as its physical realization. For JR, art is a powerful agent of transformation, offering new perspectives on the world around us. Inside 'La Caverne,' visitors will traverse a tunnel-like passage, designed to be a sensory exploration. JR describes this journey as 'a step into the unknown,' a space where opposing concepts of fullness and emptiness coexist, echoing themes previously explored in his 'Retour à la Caverne' installations across Paris, Florence, and Rome.

Adding another layer to this multifaceted experience, JR has enlisted Thomas Bangalter, formerly of Daft Punk, to craft the soundscape for 'La Caverne du Pont Neuf.' Bangalter's contribution is not a conventional musical score but an electroacoustic texture, designed to 'mineralize' the cavern's atmosphere through carefully curated resonance. Bangalter fondly recalls Christo and Jeanne-Claude's wrapped bridge as a profound childhood memory, considering it one of the most inspiring artworks he has ever encountered. The installation will also incorporate augmented reality through 'Echoes,' a collaboration with Snap's AR Studio Paris. This digital layer will introduce animated visual traces, drawing inspiration from Étienne-Jules Marey's chronophotography, allowing visitors to perceive shifting bodies, light, and movement through their mobile devices and Snap Spectacles.

The ambitious project has garnered enthusiastic backing from Paris Mayor Anne Hidalgo, who shared her personal experience of being captivated by Christo and Jeanne-Claude's 'The Pont Neuf Wrapped' in 1985, describing it as an unforgettable moment of poetry and beauty. She praised JR's talent and the wonderful idea of revitalizing this artistic gesture through his unique vision. The installation will be freely accessible to the public 24 hours a day and is designed to be appreciated from various vantage points across Paris, including the Seine riverbanks, neighboring bridges, and boat tours. Its impressive scale will also ensure visibility from elevated perspectives throughout the city.

Both JR and his team, alongside collaborators, prioritize sustainable practices in the project's development, focusing on lightweight construction and material reuse. By utilizing air as the primary structural component, the installation minimizes its impact on the historic bridge and reduces the environmental footprint associated with transportation and construction compared to traditional temporary architectural projects. Working closely with local officials and supported by the Christo and Jeanne-Claude Foundation, JR and his team are meticulously planning the installation to ensure it resonates deeply with both the city and its inhabitants. Like its predecessor, 'Projet Pont Neuf' will be financed through private funding.

Reflecting on the lasting influence of Christo and Jeanne-Claude's work, Vladimir Yavachev, Christo's nephew and the project director for the late artists, noted the significant growth of public art in Paris over the last four decades. He lauded JR's commitment to public art, recognizing him as an ideal artist to honor Christo and Jeanne-Claude's legacy. 'Projet Pont Neuf' is poised to offer Parisians and visitors an entirely new way to interact with the city's beloved bridge, celebrating the enduring interplay between art, architecture, and the urban environment, and continuing Paris's rich tradition of innovative public art.

Fujiki Studio + F.A.D.S: Exploring Seamless Architecture

Innovative Seaweed-Based Lighting Installation: Slow2 by Su Yang Choi

Designer Su Yang Choi's latest creation, "Slow2," represents a significant advancement in material and spatial design, building upon the foundations of her Slow Project series. Unveiled at the prestigious Salone Satellite 2026 in Milan, this captivating lighting installation draws inspiration from "baramgil," a traditional Korean architectural concept that ingeniously uses aligned doors and windows to generate overlapping visual pathways and natural airflow. The installation masterfully translates this ancient wisdom into a contemporary context, showcasing an innovative approach to spatial perception.

Occupying an exhibition space of 388 × 200 × 288 cm, the "Slow2" installation, measuring approximately 150 × 55 × 160 cm, employs visual layering to enhance the depth of the space beyond its actual physical boundaries. It comprises two circularly structured elements that interlock vertically and are arranged in repetitive sequences. Rather than relying on physical expansion, the design creates spatial depth through a harmonious interplay of transparency, repetition, and the seamless continuity of visual lines. The project integrates a unique biodegradable material, meticulously developed by Choi from seaweed-derived agar, completely free of synthetic chemical additives. This material is not merely a substitute for conventional industrial materials but an expression of an independent material language, possessing distinct formal and aesthetic qualities. Complementing the seaweed-based components, the installation also features LED lighting, a steel armature, insulating tubing, adhesive, and natural pigments, demonstrating a thoughtful blend of sustainable components with industrial fabrication techniques while ensuring a cohesive structural performance and visual appeal.

The formal arrangement of "Slow2" echoes the profound spatial principles found in traditional Korean hanok architecture, particularly the "baramgil" concept. This concept emphasizes aligned openings to create multi-layered perspectives, ensuring a continuous visual connection between successive spaces. Choi's installation transforms this principle into a linear composition of repeated circular elements, each approximately 50 centimeters in diameter and positioned at 30-centimeter intervals across 4.5 stacked layers. This meticulous arrangement allows for an intricate dance of light, shadow, and visibility to permeate the open structure. The construction technique pays homage to the stacking methodology of the Ten-story Stone Pagoda of Gyeongcheonsa Temple from the Goryeo period, with layers of the seaweed-based material intricately wrapped around a central metal framework. This process creates stratified linear textures reminiscent of the stone tiers in pagoda architecture. Color, derived from natural edible pigments like paprika and gardenia, transitions subtly from the material’s inherent tone at the base to deeper red hues towards the upper sections, reinforcing the organic connection between the material's composition, structural form, and the installation's biodegradable ethos. As part of the ongoing Slow Project series, "Slow2" thoughtfully examines the multifaceted potential of biodegradable materials to function as structural elements, visual systems, and spatial mediums within modern design practices, pushing the boundaries of sustainable innovation.

This innovative work by Su Yang Choi not only pushes the boundaries of sustainable design but also serves as a testament to the enduring power of integrating traditional wisdom with contemporary aesthetics. "Slow2" inspires us to consider how natural materials can be transformed into artistic and functional elements, fostering a deeper appreciation for eco-conscious creativity and mindful design that harmonizes with our environment. It encourages a forward-thinking approach, where the beauty of design aligns seamlessly with ecological responsibility.
