The facility is kinda grungy and the physical presentation may not be the best, but the content is terrific.Learn what the NSA does when it's not hacking your emails and monitoring your phone calls. Very cool, very important stuff. Be sure to take one of the tours -- 20 minutes or so.

I learned a lot about the history of cryptology and the NSA, even though I had worked with the agency as a contractor. No matter how much you think that you know, you will learn more here. The displays are great, and the explanations even more so. If you are interested in either history, language, or technology, you should definitely... More

I really enjoyed my visit to the National Cryptologic Museum. I'm not sure how well publicized it is, many locals I've mentioned it to aren't even aware it's there. It is very low key and understated, almost an afterthought to the National Security Agency offices located nearby. That does give the place a sort of ambience though. The museum itself... More

I am not going to attempt to cover the material of this place but if you are interested in spies, history, NSA or emerging technology this is definitely a cool place to visit. FREE admission, scavenger hunt for the kids with prizes at the end. Clean restrooms, vending and easy safe parking. It is a bit tricky to find this... More

I mean, the coolest thing, in my opinion, was that they have a hobo exhibit - I was not expecting that. They do offer a great overview of spy and intelligence hardware and background information. But, it is small and isolated.

We took the Baltimore-Washington expressway from DC up to the museum. We were not sure exactly what to expect when we got there. We took a wrong turn and ended up at a restricted NSA entrance and were redirected to the appropriate area. We were warmly welcomed into the museum by one of the volunteers who explained the set up... More

We stayed in Laurel, MD last year and missed the exit and ended up at this museum. That was at night so this year we made a point of coming back and visiting. The museum was very interesting with some good historical exhibits related to cryptography and the history and context of how cryptography has been used. My son enjoyed... More

We found the directions to the museum cryptologic and it took us several miscues to finally get there. We enjoyed following a tour being given as the explanations and history offered by the guide were excellent. It really made us feel old to see so much of what we lived through as now being declassified history.

This museum has loads of cryptolotical equipment and spy stuff. But the presentation and set up of the museum is not very impressive. My kids did the kids' quest piece, but they weren't engaged in the actual material. The paid International Spy Museum in Washington DC has less stuff, but presents theirs in a more manageable way. This is worth... More

Free, but a little out of the way. Could use a little paint and freshening up, but it is an absolute must if you are a history buff. Contains several German Enigma Machines - one that you can even use yourself. A U.S. Navy Bombe used to decode Enigma takes up most of a room and there were eventually over... More
