After finding my way around the castle, I finally found the PUBLIC entrance. I (wisely) rented an audio device which told me MANY things I wouldn't have known otherwise. For instance... I might not have visited the overlook where you can see the Campo del Moro which are the palaces's gardens and forest. Another... Carlos III and other monarchs are depicted as statues atop the palace. Included are Corez and Montezuma since they ruled the new world. Queen Barbara looks just like me, right?
