In 1777, Gen. George Washington established the country's first spynetwork to take on the British during the Revolutionary War. That iswhere America's spy story begins, but the $162 million International Spy Museum, in Washington, D.C., is re-imagining what spycraft looks like today.

Packedwith nearly 10,000 artifacts and interactive exhibits, the140,000-square-foot museum, which reopened to the public this weekend ina completely new space, is a completely new experience after a nearlythree-year upgrade. Visitors (who are each assigned a cover identity)can explore exhibits that pull back the veil on the lives ofinternational spies – like the so-called "Mata Hari," a Dutch spy andexotic dancer.
