Modified and added to over the centuries, these stunning palatial buildings, first built in the 10C, are notable for their architectural diversity. Highlights here include Charles V’s room, originally built in the 13C by Alfonso X the Wise; superb 18C tapestries; the palace of Peter the Cruel, a masterpiece of Mudéjar art started in 1362; the spectacular Ambassadors' hall; and the delightful gardens, where water plays an all-important role.
