In speculative fiction, floating cities and islands are a common trope, which range from cities and islands that float on water to ones that float in the atmosphere of a planet by scientific and magical means.While very large floating structures have been constructed or proposed in real life, aerial cities and islands remain in the realm of fiction.
They only appear in We Built This City and the largest one is the largest object in the Cyberpunk Penguin world.
