A Darth Vader grotesque on a church, a giant chair, the longest escalator in the Western Hemisphere, a faithful replica of the Holy Land for those who can't make the pilgrimage to Jerusalem, ingenious fencing forged from War of 1812 musket barrels, a yet uncracked cryptographic sculpture, the world's oldest continuously operating airport, the only state embassy in the nation ... Far from the crowds and the usual clichés, Washington, DC is a reserve of well-concealed treasures only revealed to those who know how to wander off the beaten track, whether residents or visitors. An indispensable guide for those who thought they knew the city well, or who would like to discover its hidden face.
