Ecumenopolis

An ecumenopolis was a city encompassing an entire planet or moon. Due to their lack of exploitable ground, such world-spanning cities were dependent on imports for food and raw materials.

Many ecumenopoleis, such as the galactic capitals of Coruscant and Hosnian Prime, as well as Denon and Eufornis Major, were situated in the Core Worlds; others were in the Deep Core, such as Troithe, and Empress Teta. City-worlds in the Outer Rim Territories included Nar Shaddaa, Taris, Uchinao, and Wind.
