Forget modern medicine and take a stab at this former Second Spanish Colonial Period military hospital where, today, costumed guides explain and at times demonstrate frightening medical procedures that took place on site from 1784 to 1821. Those with fears of doctors may want to sit this one out or at least just visit the museum’s apothecary’s garden, full of herbs still used in medicine today. A collection of antique surgical instruments may be on the macabre side, but it’s all fascinating. Tours last 40 minutes.
