AQUAPRAÇA, BELÉM, BRAZIL


Presented at the Arsenale during the Venice Biennial of Architecture, AquaPraça is a special project designed by  
Carlo Ratti Associati and Höweler + Yoon ArchitectureDrawing inspiration from Aldo Rossi's poetic exploration of architecture’s role in urban settings through his Teatro il Mondo, the project also looks to a future where architecture and the environment can coexist in perfect symbiosis.


Designed like a floating square, AquaPraça will travel from Venice to Belém in Brazil, becoming an integral part of the Italian Pavilion at COP30 (November 10th-21st, 2025). Covering an area of over 400 square meters (4,000 square feet), the project literally carves public space out of the sea, creating physical interaction between the built environment and natural forces.


The submerged structure floats by drawing on the basic principles of balance, displacement, and buoyancy. By holding and releasing water, AquaPraça constantly calibrates itself to keep a minimum distance above the surrounding water level. The public experiences dynamic fluctuations in the rising sea level at eye level, creating new perspectives on natural and urban systems.


Functionally speaking, AquaPraça can host over 150 people for exhibitions, workshops, symposiums, and cultural events. After the summit, the platform will remain an integral part of Belém's cultural infrastructure, turning into a community space for promoting ongoing social engagement. The project is being carried out in partnership with the Ministry of Foreign Affairs and International Cooperation and the Ministry of the Environment and Energy Security, and in conjunction with CIHEAM Bari and the World Bank Group’s Connect4Climate program.
