Guinness World Record - Largest Espionage Museum!

The International Spy Museum is officially the world's largest espionage museum! SPY was awarded the title by the Guinness World Records for the largest espionage museum, in terms of collection size.

As of 17 March 2020, the museum has a collection that includes 9,281 catalogued artifacts. The enormous collection tripled in size in 2017 as a result of an impressive pledged donation from private collector and espionage historian H. Keith Melton, a founding Spy Museum board member. 

From the lipstick pistol to the Enigma cipher machine, the artifacts and items featured in the collection chronicles the history of espionage, from its inception, to the modern day challenges facing intelligence professionals worldwide in the 21st Century.
