The Alcázar of King Don Pedro was apparently fortified since Roman times; this enclosure acquired its form with the Arabs and definitively with Pedro I, who had it restored in the 12th century and turned it into one of his favorite residences.
They are two spaces, one inside the other, with their corresponding walls and barbicans; on the facade facing the city, protected by a moat, is the access to the enclosure: a pointed horseshoe arch leads to a small parade ground, in which the Parador de Turismo is located today, originally defended by three towers of which remains of two are still standing.
The Catholic Monarchs built the tower and embellished the royal quarters. The 1755 earthquake severely damaged it, and since then its decline has been gradual. The Parador building is newly constructed, although it follows the style of what must have been the palace protected by these walls, and from the terrace one can enjoy a fabulous view of the Carmona plain.
