It's not often that you find a full-fledged castle in this country -- and even rarer to find one a stone's throw from the Big Apple. Greystone Court is an honest-to-goodness castle in Yonkers, N.Y. According to the property's website (yes, it's a house with its own website), it was built between 1883 and 1906 "from architectural fragments and entire 16th-18th century rooms acquired abroad." And now all that grandeur can be yours for $4.95 million and the cost of a subway ride from Manhattan. Curbed has the full story.
