Domed city

A domed city was a type of settlement characterized by a hemispherical dome covering it. Such cities were employed on planets whose natural environments were inhospitable to the physiology of their inhabitants. For example, the Geelan of the planet Needan used domed cities to protect themselves from their world's frigid temperatures. Similarly, the Bith species used domed cities to shelter themselves from the caustic atmosphere of their homeworld, Clak'dor VII.
