Barcelona, world capital of architecture: a journey through its legacy and future

From Catalan modernism to smart city planning: Barcelona is best enjoyed by looking up

Barcelona offers one of the most immersive experiences for travelers eager to discover the soul of a city through its architecture. From Gothic cathedrals to the most cutting-edge smart city planning, not forgetting the iconic landmarks of Catalan modernism, this city has positioned itself as a must-visit destination for architectural tourism. With initiatives like the World Architecture Capital 2026 and a year-round program of events, Barcelona is best enjoyed by looking up. The Catalonian capital’s architectural heritage turns every stroll into a lesson in history, design, and the urban future. In just a few steps, visitors will cross centuries of architecture: from the Gothic cathedral to the Mies Van der Rohe Pavilion, via such iconic sites as the Sagrada Familia, La Pedrera, Casa Bloc, and the Torre Glòries. The city also offers up some lesser-known gems, like Jujol’s Casa Planells and the rationalist Habitatges Barceloneta apartment building.

With the World Architecture Capital 2026 on the horizon, Barcelona’s transformation is already well underway. The Mies van der Rohe Foundation organizes a cultural calendar packed with exhibitions, tours, workshops, open days, installations, and conferences. On top of this, the international competition for ideas to remodel exposed party walls exemplifies the innovative approach shaping the city’s public spaces today. Meanwhile, this year’s Architecture Weeks, running from May 14 to June 28, present over 180 activities to experience the city through the eyes of architects, urban planners, and designers. Barcelona is a city where monumental heritage meets immersive experiences, to be experienced with all the senses. Its diverse and vibrant architecture invites exploration from every angle: as living heritage, an urban laboratory, and a showcase of innovation.
