Museum of Pharmacy
I once went to the Museum of Pharmacy1 for one złoty. My psych ward had a deal with a bunch of museums and the Kraków zoo. I'm not saying it's worth going insane sometimes. I didn't say that. But you're lucky they didn't include the arthouse cinemas in the deal.
1 Museum of Pharmacy: Kraków's Muzeum Farmacji, housed in a Renaissance townhouse. Collections of apothecary jars, alchemical equipment, and medicinal recipes from centuries past. Ironic cultural enrichment for psychiatric patients—studying historical remedies while medicated with modern ones.
