The Royal Alcazars of Seville, a World Heritage Site, is Europe's oldest palace still in use. The second story is reserved for Spain's royal family. In the 11th century, the Muslim rulers of Seville build a residential fortress here. Protected by a wall, the Alcazar site is made up of diverse palaces and gardens designed during different historical periods. Spain reclaimed Seville in the 13th century. Since then, many changes have been to the structure and the grounds and today the Alcazar combines Muslim, Gothic, Renaissance, Baroque and Romantic art. It is the best example of a mix of Islamic and Christian architecture.
