In a lovable 17th-century building, this museum has a variety of possessions and mementos of various provincial governors and caudillos (provincial strongmen), as well as religious art and fine period furnishings, including a sedan chair once used to carry around the Viceroy of Río de la Plata. Opening hours are for summer: it doesn't close mid-afternoon the rest of the year, but shuts at 7pm.
