In ancient times, when a town reached its maximum size, a "new town" was called what?

The term "Neopolis" is derived from the Greek words "neo," meaning new, and "polis," meaning city. This term was used to designate a newly established town that was developed when an existing town reached its maximum size or capacity. The concept of a Neopolis reflects the ancient practice of urban expansion and the need for new settlements to accommodate growing populations or as a strategic response to various social, economic, or geographical pressures.

In contrast, "Paleopolis" would typically refer to an "old city" rather than a new one. "Acropolis" specifically denotes a high city or citadel, often with significant religious or political importance, and is typically not used to indicate a newly founded settlement. "Polis" is a general term for city-state or city but does not imply anything about its newness or establishment. Thus, "Neopolis" is the appropriate term for a new town that arose once an existing settlement reached its peak.
