Barcelona has officially been named UNESCO-UIA World Capital of Architecture 2026, a title awarded jointly by UNESCO and the International Union of Architects (UIA).
It’s not just a shiny label. The timing is symbolic: 2026 marks the centenary of Antoni Gaudí’s death and the 150th anniversary of Ildefons Cerdà's death, the urban planner behind the Eixample grid.
At the same time, 2026 won’t shy away from the tougher realities. Barcelona is a dense Mediterranean city dealing with drought, heatwaves, and limited resources. Therefore, urban planning, green space and climate resilience are central to the conversation.
UIA Barcelona 2026: dates, congress and city-wide programme
The flagship professional event, the UIA World Congress of Architects, will take place from 28th June to 2nd July 2026. It’s expected to attract thousands of architects, planners and academics, and Barcelona will become the first city to host the congress twice.
The wider programme runs for ten months, between 12th February and 10th December. More than 1,500 activities are planned and organised alongside around 170 entities across the city. These include guided tours, workshops, debates, conferences, exhibitions and cultural performances. It's a great chance to explore Barcelona's less touristy things, rather than the headline acts.
“10 months, 10 districts”: how Barcelona 2026 reaches every neighbourhood
The slogan for the UNESCO event is “10 months, 10 districts”, and each month a different district takes centre stage, with the idea being to shine a light on the entire city.
Events will spill into community centres, libraries, municipal markets, museums and lesser-known areas in the city. It’s a deliberate attempt to reinforce the link between architecture and daily life, and to make the celebration feel shared rather than elite.
Barcelona 2026 district headquarters and key venues
Each district has a designated headquarters anchoring its programme:
- Eixample – Fort Pienc
- Les Corts – Centre cívic Joan Oliver “Pere Quart”
- Sants-Montjuïc – La Lleialtat Santsenca
- Nou Barris – Antic Institut Mental de la Santa Creu
- Horta-Guinardó – Casa de les Altures
- Sant Martí – MUHBA Oliva Artés
- Sarrià-Sant Gervasi – Dipòsit del Rei Martí
- Sant Andreu – Canòdrom
- Gràcia – Districte de Gràcia Headquarters
- Ciutat Vella – Born Market
These aren’t random picks. Many are historic or culturally significant buildings in their own right, which adds another layer to the experience.
Barcelona 2026 stamp programme: discovering all 10 districts
There’s also a playful “stamp” initiative running alongside the main events. The idea is simple: attend at least one Barcelona 2026 activity in each of the ten districts and collect a stamp at every stop. Once all ten stamps are gathered, participants can collect a small prize.
Why Barcelona was chosen as World Capital of Architecture 2026
Barcelona’s selection isn’t hard to understand when you look at its layers. There’s Modernisme, with Gaudí’s Sagrada Família and Casa Batlló pushing stone and ceramic into something almost surreal. Then there’s Cerdà’s rational Eixample grid, a 19th-century urban planning model that still feels surprisingly contemporary.
Add to that the industrial heritage of areas like Poblenou, now full of adaptive reuse projects and creative hubs, and the post-1992 Olympic regeneration that reshaped the seafront and public space. The city has a long tradition of experimenting with how people move, meet and live together.
Architecture in Barcelona: key landmarks and UNESCO sites
The obvious UNESCO heavyweights still matter. Sagrada Família, Park Güell, Casa Batlló and the Hospital de Sant Pau form part of Barcelona’s UNESCO World Heritage portfolio and remain central to its global image.
Yet the 2026 programme deliberately goes beyond these icons. It looks at neighbourhood markets, civic centres, social housing, industrial conversions and public squares as part of the same architectural story.
Is Sagrada Família going to be finished in 2026?
There have been long-standing plans to complete major structural elements around the 100th anniversary of Gaudí’s death. The basilica is already considered the tallest church in the world, and the completion of the remaining towers would push it beyond 170 metres.

La Gomera: ferries, getting around and island life
La Gomera holidays tend to suit people who like places that take a bit of getting used to. The island is small, green and quietly dramatic, and it doesn’t behave like the more polished Canary Islands nearby.
This is the oldest town in Andalusia and Spain: 5,000 years of history
In the heart of Andalusia, between arid mountains and fertile plains, lies a site that reshapes our understanding of early human settlement. Long before cities existed as we know them, an organised, fortified and remarkably advanced community established one of the most important settlements of Iberian prehistory here. Although no longer inhabited, Los Millares is considered the earliest major documented settlement in Andalusia. It emerged during the Copper Age, between 3500 and 3100 BC.
Raising a family in Spain: essential tips for expat parents
Spain has become an increasingly popular destination for families looking to balance work, lifestyle, and wellbeing. For expat parents, the appeal often lies in the sunny climate, slower pace of life, and strong family-centred culture. However, relocating with children brings practical considerations—from schooling and healthcare to visas and the cost of living.
Best national parks in Spain
This country really does spoil you when it comes to wild landscapes. The best national parks in Spain stretch across volcanic islands, snowy peaks, Atlantic cliffs and vast wetlands that feel a world away from the costas. If you’re weighing up places to explore or even live near, these five give a proper sense of the country’s natural backbone.
Juan Carlos Ferrero’s Villena academy and split with Carlos Alcaraz
On the outskirts of Villena, around an hour inland from Alicante, former world number one Juan Carlos Ferrero has built one of the most influential training bases in modern tennis. The Ferrero Tennis Academy, once a modest rural project, is now known worldwide as the place where Carlos Alcaraz developed from precocious junior to global star under Ferrero’s guidance.
