International Spy Museum - large public espionage collection

The International Spy Museum houses one of the largest public collections of espionage-related artifacts, with objects spanning early cipher devices through Cold War and modern tradecraft. The museum's holdings include examples such as an Enigma machine, KGB cipher equipment, and artifacts from U.S. intelligence operations, used in public exhibitions and research. The museum relocated to L'Enfant Plaza in 2019 to display its expanded collection and exhibitions focused on the history and practice of spying.
