It is an exhibition about cracking Enigma by the polish mathematicians:
M. Rejewski, H. Zygalski and J. Różycki who then, at the begin of the Second World War, handed it over to the Allies.
The old town is charming, the food is great and lots green space to wander around. Citadel park is worth visiting and you’ll not regret it.
Wrocław is 2 hours away and it’s a wonderful city as well. Extra fun if you like treasure hunt as the city is full of tiny gnomes for that. Extra fun with kids.
