Casa Milà, popularly called "La Pedrera" ("quarry" in Catalan), is a modernist building designed by the architect Antoni Gaudí, built between 1906 and 1910 in the Ensanche district of Barcelona, at number 92 Paseo of grace.

​

Casa Milà is a reflection of Gaudí's artistic plenitude: it belongs to his naturalist stage (first decade of the 20th century), a period in which the architect perfected his personal style, drawing inspiration from the organic forms of nature, for which he put into practice a whole series of new structural solutions originated in the deep analyzes carried out by Gaudí of ruled geometry.
