During the Middle Ages in Christian kingdoms, there were three main artistic styles: Mozarabic art featured a lack of unity, horseshoe arches, ribbed domes, and thick-walled buildings. Manuscript miniature flourished. Asturian pre-Romanesque art used rounded arches and half barrel vaults with pillars instead of columns in basilica-style churches. Mudejar art was a unique Iberian style that blended Islamic and Christian influences, featuring brick, plaster, tiles, and carved wood ceilings in buildings.
