Moat? Drawbridge? Turret? It’s a castle alright. But, unlike most others you’ll find in Europe, this one is equipped with its own bowling alley, fitness center, yoga room, golf simulator and multiple swimming pools. The 30,843-square-foot residence is located on 100 acres of land in Billings, Montana, and is on the market for $13.95 million. Photo: Engel & Völkers, via TopTenRealEstateDeals.com.
