Casa Milà , popularly known as La Pedreraor "The
stone 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 a free-plan floor, underground
garage and the spectacular terrace on the roof.
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 Mila
