A storybook castle in the middle of Cornwall, this truly enchanting property features a stone estate nestled beside a tumbling brook with ponds and waterfalls on 200 acres. Built in 1921 by socialite Charlotte Bronson Hunnewell Martin and her surgeon husband, Dr. Walton Martin, Hidden Valley Castle was constructed to be the perfect summer destination for the owners. The main house feels like a step back in time, but is suitable for modern, year-round living and there are additional living spaces such as the guest house with secret garden and heated pool, four-bedroom gate house and a two-bedroom chauffeur's apartment. The property is ideal for horse owners; there's a large three-stall stable and a six-car heated garage. Listed for $6 million by Bain Real Estate.
