Just outside of New York City, at 170 Shonnard Terrace in Yonkers, you could be living like a literal king. This property is home to a stone castle with over 20 rooms replicated to reflect 16th through 18th century European style. The castle, known as Greystone Court, began as a country house in the 1880s and expanded over the years until it became its luxurious, grand current iteration. The current owner, Kohle Yohannan, purchased it in 2000 after the property had become rundown and restored the castle to its original splendor. It is now on the market for $3.95 million.
