Mudejar architecture is a unique style that emerged in Spain during the Middle Ages, blending Islamic and Christian design elements. It developed after the Reconquista, when Muslim craftsmen continued to work in Christian territories, creating buildings that featured intricate tile work, wooden ceilings, and decorative brick patterns. This architectural style is characterized by its use of brick, plaster, and ceramic tiles, often showcasing geometric designs and calligraphy. Notable examples of Mudejar architecture can be found in cities like Seville, Toledo, and Zaragoza, where structures such as the Alcázar and the Torre del Oro highlight this rich cultural fusion.
