Does antarctica have any actual city’s

No-one lives in Antarctica indefinitely in the way that they do in the rest of the world. It has no commercial industries, no towns or cities, no permanent residents. The only "settlements" with longer term residents (who stay for some months or a year, maybe two) are scientific bases.
