This New Mexico listing is not a castle. But it does have a turret, and a couple other stone protrusions, so you can forgive us for thinking of it as the New Mexico equivalent of a castle—especially once you've seen the interiors, which are decorated in a more castle-like fashion than many United States castles we've seen. In addition, it's just a very fun house (or, "Italian Tuscan style estate," in the words of the listing) with features including a 4,000-bottle wine cellar. It's on the market for $1.85 million.
