Casa Milà, known as La Pedrera, was built between 1906 and 1912 by Antoni Gaudí in Barcelona, Spain, at number 92 of Passeig de Gràcia. The building, located on a plot of 1620 m2, is spread over six floors articulated around two internal courtyards, plus a basement, a loft and the roof, which has an independent architectural dignity.
Declared a national historic-artistic monument in 1969, since 1984 the House has been a UNESCO World Heritage Site, within the "Works of Antoni Gaudí" site.
