This is one of my favorite places to take out of town guests. Although I've been here at least 15 times in the last couple of years, I'm always blown away by the architecture and art. This Beaux Arts mansion is now home to the Society of the Cincinnati, a patriotic fraternal organization, and there are exhibitions about the American Revolution, etc. But to me the house itself, as envisioned by the Andersons (a diplomat and his writer/heiress wife) is the show-stopper. The entire house is of the highest quality. The two storey stair hall in marble features a painting depicting the wedding of a Venetian Doge- and is huge! The marble inlayed floor in orange and white in the second floor hall is stunning; tapestries in the French style sitting room are a feast for the eyes; and marvelous hand-carved woodwork in the dining room will make your mouth fall open, not to mention the ornate plaster work throughout the house. But my favorite room is the ballroom, which is two stories and is crowned with two shimmering crystal chandeliers hanging from an extraordinary wooden coffered ceiling. Twisted marble pillars hold up a musicians' balcony, and you can imagine the parties once held here. The ballroom leads to a pretty garden arcade with sweetly painted birds and trellis work. Truly not to be missed if you want a taste of DC beyond the monuments!
