There's an 18th century Spanish castle in Tennessee? Well, sort of. This 24,000-square-foot home in Johnson City, Tenn., is modeled after Palacio de la Magdalena in Santander, Spain. The estate includes 13 acres, nine bedrooms, 10 full baths, four half-baths, a billiards room, a theater, a pool, a boat ramp and dock, a 14-car garage and a 1/13-scale model of the Bristol Motor Speedway. The castle is listed at $4.3 million with Miryana Eichelberger of Alliance Sotheby's International Realty.
