Every autumn, Barcelona opens its doors—literally. For one weekend, locals and visitors get the chance to explore the city’s most fascinating buildings from the inside. The 48h Open House Barcelona Festival is not just about architecture; it’s about connecting with the city’s identity through its walls, courtyards, and rooftops.

What Is the 48h Open House Barcelona Festival?

The 48h Open House is Barcelona’s major architecture celebration, a weekend of open doors across public institutions, private homes, studios, and historical landmarks.
Over two hundred free activities invite everyone to rediscover the city through design, innovation, and heritage. Entry is free—no tickets, just curiosity and comfortable shoes.

This global initiative started in London in 1992 and reached Barcelona in 2010, thanks to the non-profit Associació 48h Open House Barcelona. Since then, it has become one of the most anticipated cultural events of the year.

A Brief History of the Event

What began as a small community project has grown into a festival involving all the city’s districts. Each edition highlights a theme—sometimes sustainability, other times urban transformation or architectural reuse.
In recent years, it has expanded beyond Barcelona to include nearby towns like Badalona, Santa Coloma, and Vilassar de Dalt, bringing architecture closer to everyday life.

When and Where It Takes Place in 2025

Mark your calendar: 25 and 26 October 2025.
For 48 hours, the festival turns Barcelona into an open-air museum. You can stroll from the modernist elegance of Eixample to the industrial charm of Poblenou, and from there to the hidden gardens of Sarrià—each neighborhood revealing a different layer of the city’s soul.

Although the festival’s heart beats in Barcelona, the 2025 edition also extends to Badalona, L’Hospitalet, Sant Joan Despí, Santa Coloma de Gramenet, Sitges, and Vilassar de Dalt—each offering a unique glimpse into Catalonia’s architectural soul.

What You Can Visit: Iconic and Unexpected Buildings

From world-famous masterpieces to little-known gems, the selection is stunning every year. Past editions have featured:

• Pavelló Mies van der Rohe – minimalism and perfection.
• Casa Bloc – rationalist housing with social purpose.
• Hospital de Sant Pau – a UNESCO modernist treasure.
• Torre Bellesguard – Gaudí’s medieval dream revisited.
• Old factories in Poblenou – reborn as creative spaces.

My Local Experience: Queues, Surprises and Tips to Make the Most of It

As a Barcelona local, I’ve attended a few editions. The truth? The enthusiasm is contagious—but so are the queues.
I remember one year waiting for more than an hour in line, watching the sunlight fade and realizing I wouldn’t make it inside before closing. I ended up skipping the visit, yet walking through the lively streets full of curious faces felt like being part of something bigger.

That’s the spirit of the festival: not only visiting buildings, but sharing a collective curiosity for the city. If you go, plan your route early and pick a few key places rather than trying to see everything.

Practical Advice to Enjoy the Festival Like a Local

• Go early – mornings have shorter lines.
• Bring water and snacks – cafés nearby get crowded.
• Check the official app or website for last-minute updates.
• Mix icons and unknowns – balance famous spots with small discoveries.
• Focus on one area – explore buildings within walking distance.

Local tip: Sometimes the least popular buildings turn out to be the most fascinating, especially when guided by passionate volunteers.
