All the buildings in Park Güell, Barcelona, Spain
If you thought one unusual building was impressive, try seeing dozens of them in one place. Gaudi knew how to turn heads, and no more so than in Barcelona’s Park Güell. It’s a strange, almost fairytale miniature city, with a real Hansel and Gretel /gingerbread house feel. The walls are inspired by trees, the buildings by abstract shapes and the colours seem to reflect the vibrancy of the surrounding, perfectly-landscaped mansion grounds. Created in 1900, it was meant to be a home for the affluent, but the idea didn’t quite take off so, 22 years later, the city transformed the area into a public park. Today, you can admire the gardens and quirky buildings for yourself. And if you decide not to stump up the cash to visit the Monumental Zone (the park’s centre), you can still get a good view of the entire park from just above it for free.
