Antarctica has been treatied off as being only for science (and in reality a small amount of military and tourism), but connected with Chile’s scientific and military bases, there’s an actual, real town! Villa Las Estrellas is the largest (of two) civilian settlements on Antarctica, with a population that fluctuates between 150-80 people. There’s a school and three children have even been born there.
The video below gives a bit more context on Antarctic treaties – Chile’s claim to territory is partially contested by both Argentina and the UK, which leads to Chile being a bit more vigorous in its assertions. Antarctica often appears on Chilean maps, Chile defines itself as a tri-continental country (South America, Oceania, Antarctica), and sometimes weather for Villa Las Estrellas is given in news broadcasts.
