Casa Milà, commonly known as La Pedrera is the largest civil building designed by Antoni Gaudi and is probably Gaudi’s second most popular building in Barcelona . The apartment block was constructed between 1906 and 1910. Situated on an asymmetrical corner lot, this large apartment building was immediately dubbed “la pedrera,” or “the quarry,” because of its cliff-like walls. Various theories have been advanced as to the source of Gaudí’s inspiration: from ocean waves to a variety of specific mountains, even a mountain crest with clouds. Regardless of the springs of creation, this limestone building seems sculptural, with contrasts between curves, concavities, and voids, with pale stone contrasting with dark iron.
Maybe one of the most interesting places of the whole complex is the rooftop: Here you can find a large ensemble of surrealistic chimneys (photo above) Many of them look like warriors in a science fiction movie, others look more frivolous. From the top of Casa Milà, you have a nice view over the Eixample district.
