This small museum, located at a 16th-century hospital and monastic complex, is packed with an occasionally wince-inducing collection of historical surgical instruments, among them an 18th-century defibrillator, a portable pharmacy kit adorned with painted Roman landscapes, and an original flagello della peste , a beak-like wooden mask worn during the city's plagues. It's also here that you can book guided tours of the neighbouring Farmacia Storica degli Incurabili, a breathtaking 18th-century apothecary magically frozen in time.
