Another impressive part of the hotel (parador) we stayed in during our brief time in Jaen.

"The castle began as an 8th Century Moorish fortress last improved by the Nasrid King Abdallah ibn al-Ahmar, who also built the Alhambra. Earlier, where the parador now stands, there was a tower known as Hannibal's Tower, of which some traces remain. After King Ferdinand III of Castile captured the city in 1246, he commenced a transformation of the castle, including construction of what became known as the New Castle on the eastern extreme of the hill. The bulk of the work, however, took place under the reigns of Alfonso X and Ferdinand IV. There are five towers and a donjon, with one of the towers holding the Chapel of Saint Catalina." (Wikipedia)
