Affiliated with the Universidad de Buenos Aires, the museum has first-rate archaeological, ethnographic, and ethnohistorical material on the Andean Northwest (bordering the great civilizations of highland Perú), the northern Patagonian Mapuche, and the Tierra del Fuego archipelago. Well organized, with good narration in Spanish only, it does a lot with what it has—and what it has is pretty good.

The Museo Etnográfico (Moreno 350, tel. 011/4331-7788, www.museoetnografico.filo.uba.ar, US$0.35, free for retirees) is open 1–7 p.m. weekdays except Monday and 3–7 p.m. weekends except January, when it’s closed. There are guided tours Saturday and Sunday at 4 p.m.
