Our first day in Gdańsk was luckily a "free museum Tuesday". Bonus!
We started at the City Hall museum. Much of the building was destroyed in the war, and has been painstakingly restored.
There is an external courtyard with some art, leading to the internal areas. We saw a lot of cool architectural elements, including a wood carved circular staircase entirely supported by the central column. I think besides the wood carvings, the most impressive aspects were the paintings on the ceilings and the incredible inlaid wood. There is a room of 20-inch tall gold beer steins from the 1690s.
The tower was closed the day we visited.
Quick and nice.
