A trip into the exciting world of codes and ciphers. This tour provides a great deal of interesting information on ancient codes, modern encryption machines, the manufacture of secret inks, pioneers of cryptology, the decryption of historical scripts and much more besides.
During the tour you will wear headphones and a transmitter. The museum guide will use a microphone to communicate with you. This ensures that you can hear clearly while you maintain the necessary distance of at least 1.5 metres.
The best option is for you to bring your own headphones with you. All you need is a standard model, for example the ones used for smartphones (3.5-mm jack plug). Those who do not have their own headphones can purchase a pair for €1 at the HNF.
You must sign a declaration of compliance with hygiene and conduct regulations. The ideal option is for you to print out the form at home and bring the signed version with you to the HNF. Please note: Each registered person has to fill out a form; in the case of minors, the form shall be signed by the legal guardian.
