Casa Milà (Catalan pronunciation: [ˈkazə miˈɫa], Spanish pronunciation: [ˈkasa miˈla]), popularly known as La Pedrera or "open quarry", a reference to its unconventional rough-hewn appearance, is a modernist building in Barcelona, Catalonia, Spain. It was the last private residence designed by architect Antoni Gaudí and was built between 1906 and 1912.
The building was commissioned in 1906 by Pere Milà and his wife Roser Segimon. At the time, it was controversial because of its undulating stone facade, twisting wrought iron balconies and designed by Josep Maria Jujol. Several structural innovations include a self-supporting stone façade, and an free-plan floor, underground garage and the spectacular on the roof-terrace.
In 1984, it was declared a World Heritage Site by UNESCO. From 2013 is the headquarters of the Fundació Catalunya La Pedrera which manages the visit to the building, exhibitions and other cultural and educative activities at Casa Milà....LESS
