Top Secret: From ciphers to cyber security

Discover the fascinating world of codebreaking, ciphers and secret communications with our free must-see exhibition Top Secret: From ciphers to cyber security.

From Alan Turing and his team of codebreakers at Bletchley Park, to one of the most successful Soviet spy rings in Cold War Britain, to modern-day cyber-crime, Top Secret explores over a century's worth of communications intelligence through hand-written documents, declassified files and incredible artefacts from GCHQ's and the Science Museum Group's historic collections.

Test your skills and challenge your friends and family to become codebreakers in our interactive puzzle zone. Trace the evolution of the gadgets and devices used to conceal and decode crucial messages. Hear from GCHQ staff doing top secret work to defend against terror attacks and find out more about the challenges of maintaining digital security in the 21st century. 

Top Secret comes to Manchester after a hugely successful premiere at the Science Museum in London in 2019, coinciding with the centenary of GCHQ, the UK's intelligence, security and cyber agency. It is the first exhibition to be held in the Science and Industry Museum's stunning new Special Exhibitions Gallery.

Free tickets for Top Secret will be available to book soon. Sign up to our newsletter to be the first to find out more and secure your tickets.
