Museum of Pharmacy, Krakow
This is a really good Museum of Pharmacy with lots of old equipment and instruments used to produce pills and decocts in the past.
You can also see the first kerosene lamp, invented by Ignacy Lukasiewicz. (He infact also built the first oil refinery in the world, in 1856.)
Fancy an unusual museum? Try the Museum of Pharmacy. Set in an old town house, this place is worth an hour of anyone's time. Not an obvious choice, but great - see historical pharmaceutical instruments, bottles, pots laid out over several floors. It's fascinating.
