It's believed that there are more spies in Washington than in any other city in the world, making it a fitting home for this museum, which displays the world's largest collection of spy artifacts. Museum advisers include top cryptologists; masters of disguise; and former CIA, FBI, and KGB operatives. The popular Washington attraction reopens Sunday at 700 L’Enfant Plaza SW — above 10th Street and halfway between the Mall and the Wharf — with a similar ratio of interactive adventures to historical artifacts that made the original Penn Quarter site a favorite since it opened in 2002.
