The Alcazar of Seville is a royal palace in Seville, Spain, originally developed by Moorish Muslim kings. The palace is renowned as one of the most beautiful in Spain, being regarded as one of the most outstanding examples of mudejar architecture found on the Iberian Peninsula. The upper levels of the Alcazar are still used by the royal family as the official Seville residence and are administered by the Patrimonio Nacional. It is the oldest royal palace still in use in Europe, and was registered in 1987 by UNESCO as a World Heritage Site, along with the Seville Cathedral and the General Archive of the Indies.
The Real Alcazar is situated near the Cathedral and the General Archive of the Indies in one of Spain's most emblematic areas.
