Guided Tours (Suspended)
Scheduled tours are normally for 6–15 people. Tours are ideal for retiree groups, college classes, or those adults looking for something a little different. Museum staff or volunteer docents lead groups on guided tours of the museum. Tours cover cryptologic history and the role that making and breaking codes has had in American/world history. You'll hear how messages were sent during the Civil War, how the U.S. entered WWI due to a decoded German message, operate a real working German Enigma from WWII, see the machine that decrypted the Japanese "Dec. 7, 1941," message, learn about the Native American Code Talkers, see some of the earliest supercomputers and secure telephones, and much more. Special emphasis can be placed on any of these areas upon request.
Groups should schedule in advance (301-688-5849) , but walk-ins are welcome if a docent is available. The minimal number for scheduled tours is six people.
Tours last approximately 1.5 hours. (Shorter or longer tours can be accommodated upon request).
School Field Trips (Suspended)
A field trip to the National Cryptologic Museum is a fun and interesting way to introduce students to the secret world of codes and ciphers. Age appropriate, interactive programs are designed to engage the students and to make them aware of cryptology's role in world history and how mathematics plays a role in cryptology. The programs are excellent for math, social studies, and scout field trips.
Hours: The museum is open to the public Monday through Friday 9 a.m. – 4 p.m. Field trips may be scheduled to begin anytime between 9 a.m. – 2 p.m. Most field trips are scheduled for the morning hours so book early to reserve the desired date and time.
Admission & Parking
A minimum of one chaperone for every 10 students is required. Additional chaperones are welcomed and encouraged.
Gift Shop (Closed While Museum is Closed)
The museum shop is open Monday through Friday 10 a.m. – 3:30 p.m. If you would like students to have an opportunity to visit the store, please schedule additional time in your trip. Students are only permitted in the gift shop with the teacher's approval and when accompanied by an adult. Because the store is small, only six students and a chaperone are permitted in the store at one time. The store carries a variety of items emblazoned with the National Security Agency emblem. Items range from pencils to clothing and books.
No public transportation is available to the museum. Ample parking is available for cars and buses. Click here for map and directions.

Other Virtual Programs
The below presenatations meet Maryland State Department of Education Social Studies Standards for grades 4–8.
- 4th Grade — Revolutionary Secrets is an interactive program that teaches students different ways messages were sent during the American Revolution and how they were disguised to keep them secret. The presentation covers Paul Revere’s lantern code, Benedict Arnold’s coded message to sell West Point, invisible ink used by Washington’s spies, and ciphers used by America’s diplomats. The worksheet accompanying the presentation lets the students try each of the different methods of secret communication.
- 5th Grade — Secrets in the Civil War is an interactive program that teaches students how cryptology was used in the Civil War by abolitionists and others. The program covers the quilt codes thought to have been used by the Underground Railroad, the cipher system of abolitionist Elizabeth Van Lew and her espionage network of former enslaved people, and the flag signaling system used by both armies and the role it played in the attack involving the 54th Massachusetts (all-black) Volunteer Regiment. The worksheet accompanying the presentation lets the students try their hand at the ciphers explained in the program.
- 6th Grade — Writing Made Secret is an interactive program that introduces students to the development ancient writing and how that writing evolved into encryption for secrecy. The presentation introduces the history of ancient writing, including Chinese, Cuneiforms, and hieroglyphics before looking at the need for encrypting written communications by the Greeks, Romans, and scholars of the Renaissance, followed by Middle Eastern scholars developing the first science of cryptanalysis in the 9th century. The worksheet accompanying the presentation allows students to try some of the cipher systems demonstrated and provides an opportunity to solve an unknown message.
- 7th Grade — Cold War: Tension and Response presents a look at various events in during the Cold War from the perspective of Signals Intelligence and the National Security Agency. Topics discussed include the Venona Project which worked to break KGB coded messages throughout the Cold War and provided information on traitors such as the Rosenbergs, the loss of aerial reconnaissance aircraft including Gary Powers’s U-2 spy mission over the Soviet Union and how that led to satellite reconnaissance, the role of Signals Intelligence during the Cuban Missile Crisis, and NSA’s role verifying compliance with the nuclear arms treaties between the Americans and the Soviets/Russians. An accompanying worksheet can be used for review.
- 8th Grade (1) — Revolutionary Secrets is an interactive program that teaches students different cryptologic methods used to protect communications during the American Revolution and how cryptanalysis of British messages aided Washington at Yorktown. Topics include the lantern code of Paul Revere which assisted in the victory at Concord beginning the war, the cryptographic methods used by American diplomats in Europe seeking French assistance, the codes used by American spies aiding the safe arrival of the French fleet in Newport, and finally the breaking of British cipher messages providing Washington with knowledge of Cornwallis’s situation at Yorktown leading to the end of the war. The accompanying worksheet provides the students the opportunity to make and break messages based on the cryptologic methods described.
- 8th Grade (2) — Signaling the Civil War is an interactive presentation introducing students to communication technologies used during the Civil War and the efforts made through cryptology to protect those communication from interception by the enemy. Topics presented include Morse Code and the use of the telegraph and how codes and ciphers protected the messages and visual signaling on the battlefield through the use of flags and how they played a role in the success or failure during specific battles. The accompanying worksheet provides students the opportunity to make and break messages based on the cryptologic methods described.
