Bedrooms/bathrooms: 6/6.5 Lot size:  0.5 acres Listing agent:  Scott Shawkey, Keller Williams Realty Open house: Sunday, November 3, 1PM – 4PM This 1898 Arlington house has its share of luxury amenities: a whiskey tasting room, rooftop terrace, and three kitchens. But it’s also not lacking in historical trivia. Toward the end of the Civil War, General Winfield Scott Hancock used the property as a headquarters for his Union soldiers: They watched over Arlington and DC from a “spy tree,” which was so tall that they operated a telegraph system from its peak. And, in another surprising twist, pieces of President William McKinley’s 1897 inaugural stand were used to construct some wall boards near the foyer.The post 4 Open Houses to Check Out This Weekend first appeared on Washingtonian.
