AquaPraça: The Floating Amazon Plaza Connecting Italy, Brazil and COP30 Climate Action (2026)

A bold vision has taken root on the Amazon River, where a unique floating plaza, AquaPraça, has found its permanent home. Designed by the innovative minds at Carlo Ratti Associati and Höweler + Yoon Architecture, this project is a testament to the power of architecture to inspire and provoke thought.

AquaPraça's journey began at the Venice Architecture Biennale, where it captivated audiences with its innovative design. Now, it has anchored in Belém, Brazil, at the mouth of the mighty Amazon, serving as a powerful symbol at the Italian Pavilion during the COP30 climate conference.

But here's where it gets controversial... AquaPraça is more than just a stunning architectural feat; it's a statement about sustainability and the circular economy. Carlo Ratti, the founder of Carlo Ratti Associati, describes it as a structure with "many lives," a concept that challenges traditional notions of permanence in architecture.

"From Venice to Belém, and now a permanent fixture in the Amazon, AquaPraça embodies the essence of circularity," Ratti explains. "It's about continuous reuse and reinvention, a philosophy that aligns perfectly with the urgent need to address climate change."

The plaza, constructed from steel and partially submerged in the water, features a unique design. Sloped floors guide visitors to different levels, offering breathtaking views and an intimate connection with the water's surface. A rectangular cut-out in the platform creates a captivating water feature, and for its Brazilian location, the designers added a distinctive square canopy that bends upwards at opposite corners.

AquaPraça aims to become a cultural landmark, a symbol of the strong relationship between Italy and Brazil, and their shared commitment to tackling climate change. Andre Corrêa do Lago, the president of COP30, praised the concept, saying, "A floating forum is truly innovative and perfectly aligns with our vision for COP30. It will create a striking presence, highlighting our dedication to sustainability."

And this is the part most people miss... AquaPraça's legacy goes beyond its physical presence. It serves as a reminder of the potential for architecture to drive meaningful change and inspire dialogue. As Corrêa do Lago suggests, it could become a lasting symbol of joint efforts and a continuous reminder of the importance of sustainability.

So, what do you think? Is AquaPraça a brilliant example of sustainable architecture, or does it fall short of its ambitious goals? We'd love to hear your thoughts in the comments below. Let's spark a conversation about the role of architecture in addressing global challenges!
