Great little museum. Shows the connection between intelligence and success in warfare. It also shows the connection between code-breaking and modern computers. Hours are not really convenient.

Definitely worth a visit if you are in to the history of cryptology from enigma to the Turing machine.

This was my third trip to the museum. If your interested in World history of codes and cyphers along with some real cool spy stuff from Thomas Jefferson to current, this is the place to go! Activities for young children to 99 years old. The even have a working cypher machine the Germans used in WWII. I found it interesting... More

What took us so long to discover this gem of a museum!!! Sitting alongside Route 32 on the D.C./ Baltimore corridor on the fringe of the NSA campus... this is a fascinating museum (free) devoted to cryptology. It spans from ancient times to the present. Worth a stop if you're in the area. Would be great for all ages. Why... More

It's amazing to see how much NSA has opened its doors to the public eye in the past decade. This little museum (located immediately outside the security perimeter of NSA) provides visitors of all ages with a glimpse if the Agency's mission. Visitors are greeted immediately by a very friendly staff/volunteer member. The museum is FREE, and contains 1-2 hours... More

As a museum I would say that it has some interesting exhibits and historical notes. I don't believe it is comprehensive in its content, as I was looking for specific items from my time in the Marines (vanity strikes deep) and there was some coverage of the era when I worked with cryptographic equipment but I would have liked to...

This is one of those little places that you will either love or find totally boring, depending on your interest in cryptology and history. Since we are interested, it couldn't have been better. Learning all about the history of cryptology and espionage was fascinating! I had never thought about a "secret service" during the Revolutionary War, and I learned what... More

Today was the second time I visited this Museum. But today a museum docent conducted a tour. The tour felt like a 90 minute College course it was so information filled. There was no other Museum like this in the United States. Go see this Museum and you will learn everything about secret codes and code-breaking in the United States.

This is about 40 minutes from Baltimore by car, and not accessible by public transportation. It's a lot closer to the airport than it is to Baltimore. But that said, if the history of codes, ciphers, and cryptology or technology is interesting, you can spend hours going through the displays. Great location for a school science field trip, boy/girl scout... More

I visited this museum with my daughter and grandchildren. It is very interesting especially if you are in to decoding. I really enjoyed the little information about the Native American code talkers who assisted during WW II as well as the Enigma machine. The museum is small in size but very large in information. For me it was overwhelming as... More
