Look closely at the materials. The building is built from exposed brick and richly decorated with polychrome ceramics, coffered wooden ceilings, wrought and embossed iron, and carved marble. The brick and the tile were chosen to work together, and that pairing is what makes the square a symbol of regionalist architecture. The structure has a central building, wings with intermediate buildings that break up the great length, and a tower at each end. Each tower rises 74 meters. The mix of styles includes Spanish Renaissance, Baroque Revival and Neo-Mudéjar, the Moorish-inspired revival, with a touch of 1920s Art Deco in the blend. González explained his thinking in his own words. He said he had drawn inspiration from the Spanish Renaissance, but modernized and reinterpreted it. And his guiding idea, he said, was that Seville is the homeland of color, so color must be handled in a way that enhances the values of the construction. When you stand beneath those towers, you are looking at that principle at full scale.
