Sanok has the castle with 600 Beksinski pieces (ranging from childhood drawings to sculptures and even his car is parked outside) which is definitely worth a trip but around Poland there are always places where more works are exhibited, prominently Kraków and Warsaw. So if you have the time you can travel around and look at art and stuff. It's a nice way to pass the time and also to gather inspiration.
