Visited the town hall after recommendations of friends who live in Gdansk! The entry price was equivalent to 3 euro. I really liked the temporary exhibition about the impact of war in Gdansk, it was really interesting. Then, when you enter the other building, you see the more luxurious rooms, but only one was impressive to me, the one which has the ceiling full of paintings. In this part, I was kinda disappointed. There was not much interesting information for me. Nevertheless, if you have time, you could go here, I would say it takes 1 hour to see everything if you read carefully.
