The International Architecture Congress UIA 2026 kicks off in Barcelona, gathering global architects to discuss sustainable urban development. Mayor Jaume Collboni emphasizes the city's commitment to innovative design.

Architects from around the globe have converged in Barcelona for the International Architecture Congress UIA 2026, which officially opened today at the historic Saló de Cent. The event marks a significant milestone as it returns to the city thirty years after its inaugural edition, showcasing Barcelona’s enduring influence in architectural discourse.

Mayor Jaume Collboni welcomed participants and highlighted the collaborative efforts of the Col·legi d’Arquitectes de Catalunya (COAC), led by its dean, alongside contributions from the Union Internationale des Architectes. This partnership has been pivotal in bringing this prestigious event back to Barcelona.

The congress aims to shift focus towards metropolitan areas, particularly emphasizing developments around the Besòs River. The inaugural ceremony will take place at an iconic site—the Tres Xemeneies, which is set to be reimagined for sustainable economic uses. This initiative reflects a broader strategy aimed at transforming urban spaces while addressing pressing environmental challenges.

Collboni articulated a vision for Barcelona that extends beyond immediate architectural concerns. He stated that no city can tackle climate change alone and stressed the importance of shared solutions designed for future generations. This aligns with his administration’s ambitious plans leading up to 2035, which include transformative projects such as revitalizing Montjuïc and enhancing coastal lines—efforts expected to surpass investments made during the Olympic Games.

The mayor also underscored a balanced approach between technology and humanism in urban planning, particularly in light of advancements like artificial intelligence. He asserted that successful cities must prioritize livability for their residents, advocating for architecture that enhances quality of life.

This year’s congress not only serves as a platform for discussing innovative designs but also reinforces Barcelona’s role as a leader in sustainable urbanism. As global architects gather to exchange ideas and strategies, they are reminded of their collective responsibility towards creating resilient cities.

The congress will run throughout this week, featuring various sessions and workshops aimed at fostering dialogue among professionals about future urban landscapes. Attendees can explore local sites undergoing transformation as part of these discussions.
