Having served in the US Army long ago -- say the Cuban Missile thing in the early 1960s -- I had great interest in seeing what the NSA would serve up at the Cryptologic Museum for that era. Nothing on display but if you ask, they will offer a handout with some information about Nam. The old saying, We Served... More

In 1966-1968 this building was a motel outside Fort Meade. Today it's hard to envision beds and a restaurant. The story of cryptology from the US Revolution to today covers a lot, the docent explaining all this to our group of Navy veterans made for a very interesting visit. There is no charge for all of this, no one gets... More

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
