The UIA World Congress of Architects 2026 will be held from June 28 to July 2
In iconic locations throughout Barcelona and its metropolitan area the UIA World Congress of Architects 2026 will be held from June 28 to July 2. In addition, there are ongoing activities associated with the Congress, both before and after the event.
In June 2026, Barcelona will host one of the largest global gatherings dedicated to architecture. Over three days, more than 10,000 participants and 250 speakers from around the world will come together across eight stages, with over 100 sessions, a 4,000-square-metre central exhibition and seventy architectural itineraries unfolding across the region. Set along the Mediterranean seafront — from the iconic Three Chimneys turbine hall to major civic venues — the Congress expands beyond a conventional conference format to experience the city. Plenary talks, lectures and debates, open forums, workshops, research presentations and public celebrations will activate the city as a concentrated space of exchange. From 28 June to 2 July, Barcelona becomes a worldwide meeting point for architects, researchers, students and institutions. This is more than a congress. Be part of it.
A unique international event that transcends disciplinary and geographical boundaries, the UIA World Congress of Architects 2026 Barcelona brings together renowned architects, researchers, and influential figures from multiple fields to promote the exchange and production of knowledge.
Held in different cities every three years since 1948, during post-war reconstruction, the 29th edition will unfold along Barcelona’s seafront.
With the theme Becoming. Architectures for a planet in transition, the event focuses on speculative, qualitative inquiries to explore material, political, ecological, and poetic interrelations. The Congress features a diverse array of events, including lectures, workshops, debates, exhibitions, visits and celebrations, all designed to encourage architectural dialogue and the sharing of perspectives.
