Occupying the former storehouses of the Asociación Rural de Tierra del Fuego, the Museo de La Ciudad Virginia Choquintel (Alberdi 555, tel. 02964/42-1767, 9 a.m.–7 p.m. Mon.–Fri., 3–7 p.m. Sat., free) does a lot with a little, with good materials on natural history, sophisticated exhibits on ethnology and aboriginal subsistence, and historic displays on maps and mapmaking, island communications, and astronomy.
Río Grande [1] has few architectural landmarks—or few buildings of any antiquity for that matter—but the Obras Sanitarias water- works tower (Lasserre 386), at the Plaza’s northeast corner, dates from the Juan Perón era (circa 1954).
El Cine 1 & 2 (Perito Moreno 211, tel. 02962/43-3260) shows current films in modern facilities, but it sometimes cranks up the volume to excruciating levels—bring or improvise ear plugs, just in case.
