On Spain tours of Barcelona, there's one thing that you can't, and probably won't even be able to, miss: the works of the master architect Anton Gaudi. His buildings seem to move like a flowing ocean, and no matter how many times you've seen pictures, nothing can prepare you for the real thing.
La Pedrera, which is also known as Casa Mila, will take your breath away. When it finished construction in 1912, the building was met with mixed reviews from residents who were unsure what to think of a structure that looked nothing like any of the other complexes in the city. Declared a UNESCO World Heritage Site in 1984, La Pedrera is just one of many buildings that have turned Barcelona into a city ripe with Gaudi.
Of course, whether you're flying, driving or busing into the city, you won't be able to keep your eyes off the spectacular La Sagrada Familia, which is still under construction to this day. The spectacular spires look as if they were made with sand because of their beige hue, but don't be fooled by their appearance. Despite still being under construction for more than 130 years, this building isn't going to blow away with the wind anytime soon.
