An Alcázar is a type of fortified palace or castle found primarily in Spain and Portugal. These structures often feature intricate architectural styles, combining elements from different cultures, including Islamic, Gothic, and Renaissance influences. Many Alcázares were originally built as military fortifications but later transformed into royal residences. One of the most famous examples is the Alcázar of Seville, which showcases stunning gardens and elaborate tile work. Another notable Alcázar is the Alcázar of Toledo, known for its impressive size and historical significance. These sites are popular tourist attractions, reflecting the rich history of the Iberian Peninsula.
