Casa Milà, popularly known as La Pedrera in reference to its unconventional rough-hewn appearance, is a Modernista building in Barcelona, Catalonia, Spain. It was the last private residence designed by architect Antoni Gaudí and was built between 1906 and 1912.

Modernisme, also known as Catalan modernism and Catalan art nouveau, is the historiographic denomination given to an art and literature movement associated with the search of a new entitlement of Catalan culture, one of the most predominant cultures within Spain. Nowadays, it is considered a movement based on the cultural revindication of a Catalan identity. Its main form of expression was Modernista architecture, but it also encompassed many other arts, such as painting and sculpture, and especially the design and the decorative arts, which were particularly important, especially in their role as support to architecture. Modernisme was also a literary movement.
