Often overlooked despite its central location, the quirky, surprising Pharmacy Museum fills five floors of a splendid 15th-century building, each done out to look like an apothecary from a particular century or, in the case of the basement and loft, an underground laboratory and herb-drying room, respectively. Furniture, chests, cupboards, and vessels are original, many taken from monasteries across Poland. The result feels authentic—you’ll get a better feel here for how locals lived than at any other standard museum.
