UIA World Congress of Architects 2026 Barcelona

The UIA World Congress of Architects 2026 Barcelona (UIA2026BCN) is a unique international event for architectural dialogue. It brings together renowned architects, researchers, and leading figures from various disciplines and invites architecture and design professionals to engage in dynamic dialogue and a collective exploration of future perspectives.

The UIA World Congress of Architects is organised by the International Union of Architects (UIA, by its French acronym), a non-governmental organisation that unites national associations of architects from over 100 countries and represents more than one million professionals. The Congress takes place every three years in a different city. In 2026, it will be held in Barcelona (28 June - 2 July), and UNESCO has consequently designated the city as the World Capital of Architecture 2026.

UIA2026BCN is organised by the Higher Council of Spanish Colleges of Architects Guilds (CSCAE), in collaboration with the Architects ́ Association of Catalonia (COAC) and the participation and financing of the Ministry of Housing and Urban Agenda, the Generalitat of Catalonia and the Barcelona City Council.

The organising administrations offer institutional support and co-finance the UIA World Congress, which has been declared an event of exceptional public interest in Spain’s 2023 General Budget Law.

Marta Vall-llossera (President of the CSCAE) holds the Presidency of the Congress, with Teresa Táboas (Vice President of the UIA and President of Region I) as Vice President and Guim Costa Calsamiglia (Dean of the COAC) as Congress Director. Joan Busquets serves as Honorary President of the Congress, and Fuensanta Nieto as President of the Scientific Committee.

For the first time, the congress is framed by a curatorial proposal. "Becoming: Architectures for a planet in transition" by Pau Bajet, Mariona Benedito, Maria Giramé, Tomeu Ramis, Pau Sarquella, and Carmen Torres, will define the #UIA2026BCN.
