The UIA World Congress of Architects 2026 Barcelona has released a preliminary preview of its programme of lectures, as well as further details on  the various formats that will attract more than 10,000 professionals from all over the world, from the fields of architecture, landscape design and  urban planning, the institutional sphere and the student community to gather in Barcelona in 2026. After thirty years, the city will once again host  this World Congress, which will welcome renowned figures in contemporary architectural thought and practice.

With a multidisciplinary approach, Barcelona will become, for five days (28 June - 2 July 2026), a global laboratory and hub for debating  forthcoming ecological, social, material and cultural transitions. The week preceding the Congress will feature an international workshop for students and young architects, while the main exhibition will be open to the public for four weeks, engaging citizens and the general public in learning about some of the most relevant projects and research presented at the symposium.

Tickets to attend the Congress are now on sale and will provide access to the programme of talks, activities and the exhibition taking place at the Barcelona International Convention Centre (CCIB), the Three Chimneys —transformed into a major seaside venue—, the Disseny Hub Barcelona, and other locations across the city, distributed among different neighbourhoods, such as the Montjuïc Castle and the Sagrada Familia.
