The Battlement Castle
This is one of the more expensive properties on this list, but once you see these ruins and their potential, you’ll understand why. Since the gorgeous renovations in the early 1900s, this Spanish castle looks like it’s straight out of a movie. It dates back to the 13th century when it was previously an outpost for the military. You’ll get the aged abode, with 50 living spaces, a pasture with Iberian pigs, and a museum for 14.5 million euros (Bobvila).
