The Royal Palace of Aranjuez is one of the official residences of the Spanish royal family. It is located in the town of Aranjuez (Madrid), Spain. Established in the 16th century as a royal hunting lodge, the palace was built by order of Philip II. Under his reign it became one of four seasonal seats of the court along Rascafría, El Escorial and the Royal Alcázar of Madrid. The royal estate comprises a set of landscaped and ornate gardens and woodlands that house an extensive botanical collection.

Patrimonio Nacional is a Spanish autonomous agency, under the jurisdiction of the Ministry of the Presidency, Justice and Relations with the Cortes, that administers the sites owned by the Spanish State and used by the Monarch and the Spanish Royal Family as residences and for State Ceremonies. The Patrimonio Nacional includes palaces, gardens, monasteries and convents, called the Royal sites. When not in official use, the Royal sites are open to the public. It also manages the official and holiday residences of the Prime Minister.
