Museums
The Enigma Cipher Centre at 78 Święty Marcin Street tells the Poznań story behind the breaking of the Enigma cipher. Polish mathematicians Marian Rejewski, Henryk Zygalski and Jerzy Różycki studied cryptology here. The multimedia exhibition follows the story from early secret writing to computers.
This is not a display of cases alone. An audio guide and interactive stations let you solve ciphers, try the Caesar cipher and follow the cryptologists' methods. You will see original Enigma models and devices including Zygalski sheets, bombes and a cyclometer. The route links cryptology with computing.
The story begins with the cryptology course launched in Poznań in 1929 and leads to information security today. The audio guide is available in Polish, English, German, Russian and Ukrainian, with audio description, easy-language and Polish Sign Language tracks. Allow about two hours and consider the Mediatheque.
The Centre is open Tue–Fri 09:00–18:00 and weekends 10:00–19:00; Mondays closed. Tickets cost 35 PLN standard, 29 PLN reduced and 75 PLN family. Entry is timed every 15 minutes in groups of up to 15; last entry is one hour before closing. Buy online or at the venue. A technical break was listed for 7–11 September 2026, so check the latest notice. Nearby stops include Zamek and Fredry.
Tripto tip: do not treat this as a quick biographical museum. Leave time for the puzzles — they show how the Polish mathematicians' success depended on method, teamwork and patient testing.
