About
The National Cryptologic Museum houses thousands of artifacts that collectively tell the history of the cryptologic profession. Here visitors catch a glimpse of some of the most dramatic moments in the history of American code making and code breaking: the people who devoted their lives to cryptology and national defense, the machines and devices they developed, the techniques they used, and the places where they worked. The museum library maintains a collection of unclassified and declassified books and documents relating to every aspect of cryptology.

- LAURIE SBuckhannon, West Virginia439 contributionsSecret history in the makingThis small museum, staffed by volunteers who are very knowledgeable about cryptography, make an interesting few hours. Their galleries span from colonial times through the space age explaining how cryptology evolved through the centuries. There are a lot of free brochures after viewing the exhibits. Look for the specific brown signs off the highway to exit for the museum. This is a free museum which accepts donations.Visited May 2023Travelled as a coupleWritten 16 May 2023
- Nomad249 contributionsTinker Tailor Soldier SpyTake a deep dive in intel. Aside from the excellent ENIGMA display, this place is historically significant in that this is the approximate location where codebreakers quietly and systematically uncovered the extent of communist infiltration in the US existing at the highest levels of US government agencies, the arts, journalism, academia, etc, Known as project VENONA, this blew the lid-off of communist agent infiltration and also exposed the “Cambridge Five” (Kim Philby, Guy Burgess, etc - all communist moles working within the highest levels of British Intel). Was Senator Joseph McCarthy (who died in disgrace) correct all along? Take a look at VENONA and then you decide.Visited September 2022Travelled soloWritten 23 July 2023

The National Cryptologic Museum is a small hidden gem located near NSA Headquarters located on a circuitous route among several major highways. Thank heavens for map apps. The museum is located in a small one-story building. There are two main display halls and a large room for meetings/conferences, one of which was happening while we were there. Fortunately, entry was free, and movement among the displays was easy. Staff at reception were quite friendly and explained the setup as well as pointing us to a small room with free pamphlets and, surprisingly, a gift shop. We were most impressed with the pre-computer era displays, including everything from code books and typewriter like machines that created code, such as the famous WWII Enigma machine. The gift shop has the usual caps and t-shirts, but the fun came from a "thermographic" hot sauce, and "classified", "unclassified", "declassified" blends from a local coffee roastery. Each display item had an easy to read explanatory card. This is a great place to learn about the people, techniques, and machines that operated under the radar in important world events.

Great visit! Very informative although more context and explanations are required. I was left with desire to understand more and do my own research. My son, 15, was really into it.

They did have some very famous artifacts/machines there, and a real Enigma to play with (cool) but… the information for most off them was very sparse (eg no in depth description about the inner workings, if you are really curious to dive deeper). No QR codes for at least SOME of the machines.
You end up having to take pictures as a reminder and then go online to read up on Wikipedia.
All told: all of us (3) were actually underwhelmed and left a bit disappointed.
Sorry, this museum needs a bit modern 21st century TLC…

Attended Grand Re-Opening today - Museum has been closed for more than 2 years due to COVID. Awesome experience - wonderful exhibits and knowledgeable staff. Hard to believe they have a Hitler Enigma Machine along with other rare code equipment. Give it highest marks - a must do!!!

If you are the least bit interested in spies or espionage then you'll want to visit here. On display are all kinds of equipment the U.S. used in various wars. Most of which I'm sure you never heard of or saw. You can request a guide.

Thanks for your review. It's important to note that the National Cryptologic Museum does not focus on espionage the way many people think. That is, the history of cryptology is about the history of codemaking and codebreaking, not so much as people working "behind enemy lines" pretending to be the enemy, collecting information, and sneaking it back to those for whom they were spying, That is more what is called human intelligence. Here we have hundreds of artifacts, machines, and devices used to create and break codes and ciphers, the men and women who designed and used these tools, the methods they employed, and their impact on American and world history.

How do you travel from the Greenbelt Metro Station to the Museum without a car?
thegbb
Annapolis, MD35 contributions
This museum is not downtown, and there is no Metro near this part of Maryland. It is not easily accessible without a car unless there is a group/tour bus going there. If you really want to go to this museum and any other locations outside of the immediate DC suburbs, I recommend getting a zip car or car2go for the day.
How much is the museum admission fee?

I do not park busses but there seemed to be plenty of parking in their lot. The lot is adjacent to the museum.
