This is not called the patio museum for nothing. There are 12 highly fascinating patios that surround the palace. These patios - lush with orange trees, myrtle plants, palm trees, cypresses and flowers - are treasures in themselves. But the palace also holds a wealth of historical items, such as paintings, tapestries, furniture, porcelains and so many others. There is also a library with 7,000 volumes.
