Reales Alcázares
This fortified palace is the oldest still in use in Europe. The Umayyad governors of Seville began to build it. Then the Abbadies and later the Almohades. Of those Islamic palaces there is little left except the wall and not much more. However, the most famous part of this amazing palace, ordered by the King Don Pedro, will not be strange to you: it comes from the hands of the best Muslim 'alarifes'. It's World Heritage site.
