The Spy Museum in the Finlayson area focuses on intelligence history from the 18th century to the present, with a particular emphasis on Cold War espionage. The collection includes genuine surveillance equipment, disguise kits, miniature cameras, and cipher machines from multiple intelligence agencies. A section on Finnish intelligence and the country's position during the Cold War is especially interesting given the context.
The interactive elements are well-designed and work for adults as well as children. You can try your hand at disguise scenarios, dead drops, and code-breaking. Budget 90 minutes to two hours to get through everything properly.
