Exciting opportunity to own a STONE CASTLE, built circa 1890, close to DC with a 2 Bedroom Guest House. Completely renovated, reimagined and expanded by renowned DC builder and architect Clarence Kettler in the late 1980s as a personal residence. The main house features 5 Bedrooms, 4 Bathrooms, 2 half baths, ELEVATOR, Chef's Kitchen, 3 Decks, Winter Potomac River Views and attached 2 Car Garage, with 4 Bedrooms and 3 Baths, including the Master Suite, on the second level. The third level features a Bedroom, Bathroom and Play Room with access to a ROOF DECK with fabulous views. The lower level has a Billiard Room and Study. The Elevator accesses three levels. A UNIQUE and SPECTACULAR one-of-a-kind offering. This property is one of three Stone Castles built by the Baltzley Brothers, who envisioned these houses in Glen-Echo-on-the-Potomac, also known as the Washington Rhine. The stone for the Castles came from local quarries operating on Seven Locks Road. The Brothers also built the Glen Echo Railroad to provide access to the nearby Glen Echo Amusement Park (which was constructed using the same stone). Perfectly located, just minutes to Downdown Bethesds, Washington DC and Northern Virginia
