On the 3rd floor of a grand former hospice building is this museum explaining the evolution of Garrotxa's industry, culture and population. It isn't gripping but you'll learn interesting nuggets about clog making, the popularity of cornflower soup, and famous residents. You'll also eyeball some local art and learn some context for the area's history. Labels are in Catalan, but there are explanations in Spanish, French and English in handy booklets.
