They say a man's home is his castle, and one Kentucky resident took that to heart. After a European vacation in 1969, wealthy developer and contractor Rex Martin and his wife, Caroline, were so inspired by the architecture they saw that they began construction on a palace of their very own. Plans for the land just outside Lexington included seven bedrooms, 15 bathrooms, and a fountain in the driveway. In 1975, current owner Tom Post bought the property for a cool $1.8 million. Post went on to spend nearly double the original value of the place on remodeling, and the Castle Post is now a hotel, complete with a library, game room, and luxury suites in each of the castle's four turrets.
