Originally designed to house artifacts from the Agency and to give employees a place to reflect on past successes and failures, the Museum quickly developed into a priceless collection of the Nation's cryptologic history. The Museum opened to the public in December 1993 and immediately became a highlight of the area, being called, "America's Hidden Treasure."
Being one of the first public museums in the Intelligence Community, the Museum hosts approximately 70,000 visitors annually from all over the country and throughout the world, allowing them a peek into the secret world of codemaking and codebreaking.
The Museum is also an invaluable educational tool, benefiting thousands of students and teachers every year. Staff and docents provide students of all ages the chance to learn about cryptology's impact on history and the possibility of exciting jobs in an area they may not have thought possible.
The Museum has been featured in a plethora of international TV, print, and radio media and has hosted visitors and dignitaries from around the world.
National Vigilance Park, which stood adjacent to the Museum, is temporarily closed. Its three aircraft are in storage. The park showcased Army, Navy, and Air Force reconnaissance aircraft used for secret missions. The Museum anticipates returning them for display in the 2022–23 time frame as part of the future upgrades to the Museum and National Vigilance Park.
