Casa Milà, also known as La Pedrera, is a building designed by Antoni Gaudi, built between 1905-1910, located in the Eixample district of Barcelona. The house was built for built for a married couple, Rosario Segimon and Pere Milà.
Like much of Gaudi's work, the building was controversial in its day. The municipality objected to much of the project, fined the owners for various building code infractions and ordered various aspects of the project to be demolished. The building grew into disrepair until the 1980's but has since been restored and is now a UNESCO World Heritage Site.
The highlight of the building is the rooftop. The surface of the roof is covered with undulating slopes and odd chimneys designed in fantastical shapes. They remind me of scary, gothic comic book figures.
