Barcelona is filled with buildings that form part of our everyday landscape but that we can't always see from the inside. 48H Open House Barcelona 2026 returns on October 24 and 25 to open the doors to over 250 buildings and spaces across Barcelona and its metropolitan area.
Throughout the weekend, you can discover architecture from different eras and styles, ranging from palaces and Modernist buildings to contemporary facilities. Here are 6 spaces from 48H Open House Barcelona that are well worth having on your radar.
1. Torre de la Creu
If you want to step outside central Barcelona, head to Sant Joan Despí to discover one of Josep Maria Jujol's most unique works.
Built in 1916, Torre de la Creu was Jujol's first project in the municipality. The residence is composed of five cylinders of varying heights, topped with parabolic domes that give it its iconic silhouette.
How to get there:
Rodalies commuter train: Lines R1, R4 to Sant Joan Despí.
2. Palau del Marquès d’Alfarràs
Located next to the Horta Labyrinth Park, you will find one of the most remarkable sites of 48H Open House Barcelona 2026. Palau del Marquès d’Alfarràs has its origins in an 11th-century defense tower, and the current complex preserves eclectic and Neo-Moorish architectural elements.
In the 18th century, the estate came into the hands of the Desvalls family, who expanded the palace and commissioned the construction of the famous gardens. 19th-century renovations gave the site much of the appearance it retains today.
How to get there:
Metro: Mundet (L3).
3. Biblioteca Arús
Located on Passeig de Sant Joan, Biblioteca Arús occupies a former residential building transformed into a public library. The entryway is one of its most striking features, showcasing a grand three-flight marble staircase and noble materials.
Today, it is a research center specializing in contemporary social movements and 19th and early 20th-century literature and press.
How to get there:
Metro: Arc de Triomf (L1) or Tetuan (L2).

4. Casa Rocamora: A Mansion in the El Putxet Neighborhood
Tucked away in the streets of El Putxet is Casa Rocamora, a 19th-century Elizabethan-style mansion linked to Manuel Rocamora i Vidal, a painter, writer, and avid collector.
Rocamora gathered collections of paintings, ceramics, sculptures, furniture, and fashion, reflecting various periods in the history of decorative arts. Among the notable pieces linked to his legacy is an Els Quatre Gats poster designed by Picasso and works associated with Ramon Casas.

5. Arc de Triomf
You have likely passed by it many times, but you may have never stepped inside the Arc de Triomf. Built for the 1888 Barcelona Universal Exposition, it was designed by Josep Vilaseca i Casanovas.
Its design combines the proportions of a classical triumphal arch with materials and ornamental details inspired by Neo-Mudéjar architecture.

The former headquarters of Editorial Gustavo Gili, currently linked to Barcelona's Casa de l'Arquitectura, is a great stop to discover an architectural style distinct from better-known Modernism.
Built in the 1950s, the building stands out for its Rationalist language, the use of exposed concrete, and the organization of interior spaces around central courtyards. Natural light, ventilation, and the relationship between workspaces form the core of its architectural vision.
How to get there:
