La Sagrada Família

La Sagrada Familia interior

Of all of architect Antoni Gaudí’s works in Barcelona, La Sagrada Família has to be the most iconic.

Set to be the world’s tallest church when it is completed in 2026, La Sagrada Família sees more than 3m visitors annually. It is the sixth most reviewed attraction in the world on TripAdvisor, with mostly positive reviews. (Famously, George Orwell wasn’t a fan, saying it was “one of the most hideous buildings in the world” and that he hoped it would be destroyed during the Spanish Civil War).

Whether you consider it gaudy or a work of genius, it is difficult not to be impressed. You’re unlikely to have the place to yourself however, but the visitor numbers are managed reasonably well.
