I used to live in Maryland and I basically always tried to drag people over here. I actually found that I liked going to the Cryptologic Museum even more than the International Spy Museum down in DC despite how flashy the latter is (of course, the Cryptologic Museum is free to enter so that helps...). Anyway, there's all kinds of... More

My husband and some friends have urged me to go to this museum and it was well worth a visit. There is a lot of information on codes and ciphers and how they were used in different eras, especially in times of war. There are also profiles of key people involved in the field. We did a self-guided walk-through because... More

This is a little bit out of the way, right beside NSA off of US 32. I was on a business trip and had time to kill... Glad I did. whether you are a math whiz, history buff, or a "Cryppy" this will intrigue you. Starts all the way back in 1800s... Codes, machines, techniques, technology. They have tours that...

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
