A decorative and architectural style, part Islamic and part Gothic, which evolved in Spain after the reconquest of the peninsula from the Moors between the 13th and 15th centuries. It was created by Muslims working for Christians and also by Christians influenced by Muslim design. The name derives from an Arabic word meaning ‘allowed to remain’. Perhaps the best-known example of Mudéjar architecture is the Alcázar in Seville.
