Marty’s photo of the day #2586: I’m pulling a paragraph from my first book, Cool Creatures, Hot Planet: Exploring the Seven Continents, to give you information on this Spanish castle:

Twenty minutes into our drive, we rounded a corner and came upon a classic crusader-era castle. Perched alone on a hill, it had a circular tower at each corner and appeared to be in pristine shape. I didn’t see any signs identifying the castle, but later, when I purchased John Gibson’s book Anatomy of the Castle, I opened right up to a full-page photo of it. Called the Castillo de Albuquerque, it was built between 1461 and 1476 by the first Duke of Albuquerque, and it is still owned by his descendants.
