One of the most renowned Spanish architects of all time was Antoni Gaudi. Gaudi's emergence as one of 's preeminent artists at the end of the nineteenth century marked a milestone in the art world.

Gaudi's popularity helped to bring about the acceptance and rebirth of the Catalan language, which had been banned during the literature and art. Gaudi shares his Catalonian background with two other famous Spanish artists, Pablo Picasso and Miro. The diverse ethnic background of the region greatly influenced the work of Picasso and Miro, as well as Gaudi. Thus, their works were a combination of an old history and an active, vivid imaginary world. This has sometimes been referred to as the “Catalan Mind.” Yet it was perhaps Gaudi who had the greatest talent for bringing together diverse groups, ones which others viewed as being too diametrically opposed to be capable of coming together and co-existing amicably.
