This little museum is across the street from NSA headquarters on Ft. Meade, but is accessible to anyone. While small, it is crammed full of interesting history on cryptology, with much of the displays centered on World War I and II. They have unique displays cryptographic equipment and the people who used it, starting back to the Revolutionary War. The... More

This museum is near NSA between Baltimore and DC. It is not huge, but displays are attractive and informative, and they have some great things. The best part was the tour led by a man who worked at NSA. He spent nearly an hour with us and one other family. Since I have little background about spy codes, I would... More

I found a lot of the information was too dense. I did enjoy reading some of the stories about how people communicated secretly, but it can't compare to the museums in DC. Good effort to make some hands on exhibits for kids, my son liked that part.

I took the Canine Exit 10, and got a bit confused as the which direction to take once I got off. There is an NSA Vistitors Center to the far far right, and the museum road is to the far far left (follow signs for gas station, frontage road.) There might even be a special exit a bit up the... More

A free attraction of cryptology within our nation; who would have guessed you could have a museum from that topic. This shows the history of how we kept our secrets secret while attempting, and frequently succeeding, in exposing the secrets of others. There are many fascinating exhibits and frequent tours given by the volunteers there. They make a good effort... More

This is the least expensive (free) if furthest museum (of 4 or 5, if you count) devoted to security and intelligence in the DC metro area. The pricier the Intl. Spy Museum will cost you about $16, but it's downtown near the FBI bldg. The others are even harder to enter (I've been in maybe 3). The former Colony 7... More

We came here today for 2 reason: 1. The review on tripadvisor. And 2. My 16 year old daughter's interest in this area. This is a FREE museum near NSA in Baltimore. We have friends in this area who have not heard of this place. This is a great museum. My 13 year old son enjoyed the kids challenge. When... More

We have visited this compact museum two or three times. It is packed with fascinating displays and you will come out wondering where the last 2 hours went. It is immediately alongside the NSA complex and there is an NSA gift shop selling a range of souvenirs. There are vending machines for refreshments. Great fun to send/receive coded messages using...

My family has lived in the Maryland suburbs of Washington, DC for many years and none of them had heard of this musem. Learn about how... More
