Casa Museu Gaudí in Barcelona

You're standing at the Gaudí House Museum, right inside Park Güell. For almost twenty years this was the home of Antoni Gaudí, the architect who gave Barcelona its unmistakable look. Take a good look at the house. Here's a surprise: Gaudí didn't actually design it. His colleague Francesc Berenguer did, although Gaudí put his signature on the plans.
