The Secret World of Intelligence is detailed here with interactive displays and cipher technology from the 16th century to today. One section details the activity of spies during the Revolutionary War, especially General Washington's Culper Spy Ring, and allows visitors, especially children, to "Create Your Own Secret Cipher," "Hidden Message," "Invisible Ink Secrets," and "Make a Secret Code with a...

Definitely worth the visit. No charge for admission, donations are appreciated. Well designed museum displays and artifacts. Highlights include the seal donated by Russian schoolchildren during the Cold War, the Cray computers, and Enigma machines. To find it, you need to make a left right before reaching the NSA pylons (play chicken with the cars leaving the NSA compound!), and... More

The real challenge with this place is getting there. I'm sure the NSA doesn't get hugely excited about visitors, but they could have done a nicer job of pointing people to the museum. My GPS seemed to be leading me elsewhere, so I followed signs from the highway that led to a parking lot (N-10). The lot seems to be... More

This small and somewhat difficult to find (DO NOT turn in at the NSA gate or you will find yourself politely but firmly submitted to some scrutiny before being pointed in the right direction) is an absolutely gem. Although it's listed as being in Baltimore, it is south of Baltimore, much closer to Ft. Meade. The collection is wonderful and... More

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
