Reviving Monument: Luxembourg Pavilion Concrete Blocks Reused at NESTA Resort Kobe

Transforming the Luxembourg Pavilion's Legacy

In May 2026, the NESTA Resort Kobe will unveil a unique monument crafted from the re-used concrete blocks originally part of the Luxembourg Pavilion at the 2025 Osaka Kansai Expo. This innovative initiative, led by Senba Co., Ltd., in collaboration with the Luxembourg Economic Interest Group (GIE) and NESTA Resort Kobe, marks a significant step in reinterpreting the concept of sustainability and reusability within architectural practices.

The Luxembourg Pavilion, designed with a strong focus on circular economy principles, aimed to facilitate the repurposing of as many construction materials as possible even after the expo's conclusion. Recognized for its thorough reuse efforts, the pavilion was awarded the Sustainability Prize by the BIE (International Exhibitions Bureau). Now, the concrete blocks, which weigh approximately 2.4 tons each and would typically face demolition and downcycling, will find a second life as a retaining wall to prevent soil erosion in the NESTA Resort's premises.

Merging Art and Architecture

Beyond functioning purely as a retaining structure, the reimagined concrete blocks will also feature a striking mural by renowned artist KAC (Kеeshi). The artwork is a testament to the pavilion's memory, bridging the past with the future. Scheduled for completion in May 2026, this emblematic monument measures approximately 150 meters in length and 1.6 meters in height, seamlessly integrating with the landscape of NESTA Resort Kobe. KAC’s murals, which often draw from urban graffiti roots, transform mundane concrete surfaces into captivating pieces of art that evoke emotions and memories.

KAC, born in Hiroshima in 1988, has garnered recognition for his ability to convey complex emotions through vibrant large-scale murals. His unique style focuses on intertwining urban narratives with themes of time and memory, a reflection that aligns perfectly with the sustainable mission of the Luxembourg Pavilion.

A Commitment to Sustainability

Senba Co., Ltd. assessed the potential for domestic reuse of the pavilion's main architectural elements and coordinated with various stakeholders to ensure the successful repurposing of the concrete blocks and some external panels at NESTA Resort Kobe. By utilizing these materials locally, the project not only mitigates potential CO2 emissions but also preserves the rich narrative embedded in these blocks. Instead of being crushed and downcycled— an approach that often incurs environmental costs and inefficiencies—these blocks are being preserved as carriers of memory and history.

The original Luxembourg Pavilion, encapsulated under the theme „Doki Doki – The Luxembourg Heartbeat,” welcomed around 378,000 visitors during the expo, actively showcasing Luxembourg's commitment to sustainability. Designed by the architectural firm STDM and spatial designer jangled nerves, the pavilion stood out with its membrane roof and steel structure, representing both innovation and sustainability through its design.

Continuing the Legacy

This monument represents a new chapter in the life of the Luxembourg Pavilion’s concrete blocks, embodying the lively spirit of its original purpose while engaging the public at NESTA Resort Kobe. As it bridges the legacy of the pavilion to future generations, it encapsulates the essence of “Doki Doki” through the physical transformation of materials and emotional connection to visitors who will experience the monument in person.

KAC eloquently expressed, "Much like the cycle advocated by Luxembourg, the concrete that once supported the pavilion will now find new life above ground, creating a pulse in the landscape of NESTA Resort Kobe. It’s not just about the bricks; it’s a manifestation of memories and emotion escaping the confines of time. I look forward to creating a wall that resonates with new feelings and landscapes that emerge from our unseen past."
