There are some rowhouses in D.C. that kind of resemble castle towers with their old brick and turreted roofs. However, this one bedroom apartment in Dupont actually is located in a historic castle, the Captain Frederick A. Miller House, on Massachusetts Avenue. The 825 square foot apartment has regal offerings like a double vanity and a wood burning fireplace. The 8 inch moldings and exterior stone work also add to the appeal of the building from 1900. If this appeals to your inner historian (or inner king/queen), it's going for $524,900 and we have more photos after the jump.
