Sprawling medieval-style complex built in the 1920s by inventor John Hays Hammond & open for tours.
"Though this stone castle might look like it’s straight out of medieval Europe, it was actually built in the 1920s by inventor John Hays Hammond Jr. to serve as his home, laboratory and gallery for his sizable collection of Roman, medieval and renaissance era artifacts and antiquities. Today, you can see the collection and check out exhibits about the former home owner's life and inventions as you tour Hammond Castle, including the guest bedrooms, war room, and manicured grounds.
