Nice venue and prices are fair but I found it a bit lacking and was expecting a bit more. The courtyard is very pretty for photos.

I've published seperate review for the military museum which is in the same building. This place holds a really nice collection of items found in Silesia and has a medieval section on the ground floor, with artifacts from the Stone/Bronze and Iron ages on the 1st and 2nd floors. I particularly loved the stone age tools, like the flint shards used for cutting. To think human hands held these tools 4000 years ago is something special. This place would be 5 stars if there was more English explanation. There is a small guide on each floor in English but generally just gives a list of the items without much context or explanation. Almost no one there when I visited.

Amazing military museum with an assortment of weapons, helmets, and uniforms. I was happy to see the Sturmgewehr 44, the predecessor to the AK - 47. The museum also housed the American Thompson sub machine gun, the gun of choice for American gangsters during the Prohibition era. The archeological museum contained interesting trinkets and a full skeleton from the 1200s.
