Also known as Mudéjar Palace, it was built next to the Alfonso X Gothic Palace at the initiative of King Pedro I between 1356 - 1366, artisans from Toledo, Granada and Seville itself collaborated in its construction. Later it was transformed at the time of the Catholic Monarchs and the first Austrias. This palace was born to serve as the private building of King Pedro I, built in the previous century by order of Alfonso X. He used Arabic epigraphy to exalt his virtues. This is because, from the fourteenth century, the Castilian monarchs stop copying European trends to be inspired by Andalusian models. This caused this palace to house various writings in Arabic. The interior is structured around two cores, one dedicated to the official life that is located around the courtyard of the Maidens and another to the private one around the courtyard of the Dolls. Walking along the galleries and rooms decorated with beautiful tiles and beautiful Mudejar ceilings, from the lobby you reach the courtyard of the Doncellas, main courtyard, a masterpiece of Andalusian Mudejar art. From the entrance to the courtyard of the maidens we find the Alcoba Real on the right, in front of it is the Ambassadors hall and on the left the Carlos V. Ceiling room On the top floor of the palace are the royal apartments, redecorated in the century XVIII. It has a first floor that does not extend throughout the ground floor, but only for some rooms.
