/ Casa Batlló by Gaudí is one of the great buildings of the 20th century, a must-visit when you are in Barcelona. This unusual house looks alive, with curved lines and organic shapes creating a wonderful experience. We learn about it from our excellent guide, Sandra Benzal, who you can find through aguideinbarcelona. Sandra explains that Antoni Gaudí rebuilt and designed this structure on commission from the Batlló family, who wanted a new home in the Modernist style in the early 1900s. Beautiful when viewed for free from outside, on Passeig de Gràcia, it gets more interesting when you pay to go inside, as we show you in this video. Walk up the beautiful staircase to the main room with its amazing large curved window for a very special experience, then continue to the roof-top and see the ceramic dragon.
