Punta Arenas Punta Arenas (or Sandy Point in English) is the capital city of Chile's southernmost region, Magallanes and Antartica Chilena. The city was officially renamed as Magallanes in 1927, but in 1938 it was changed back to "Punta Arenas". It is the largest city south of the 46th parallel south. As of 1977 Punta Arenas has been one of only two free ports in Chile. (Note that Punta Arenas itself is not a "free port", but rather outside of the city; there is a small "zona franca" where certain products can be imported into the country under a reduced-tax regimen.)
