What term denotes an "old city" in ancient Greek context?

The term that denotes an "old city" in ancient Greek context is "Paleopolis." This term derives from the Greek words "paleo," which means "old," and "polis," which means "city." Therefore, Paleopolis literally translates to "old city" and is used to refer to the remains or ruins of an ancient city that has historical significance.

Other terms might relate to cities or urban concepts in ancient Greece, but they do not specifically convey the idea of an "old city." For instance, "Poleis" refers to city-states in general, representing independent territories often centered around urban centers. "Neapolis," meaning "new city," stands in contrast to Paleopolis as it suggests a place that is newly established rather than old. "Akropolis" refers to a high point or citadel in a city, commonly used to describe a significant elevated area in Greek cities like Athens, but again does not indicate the concept of being an "old city."

In summary, Paleopolis is the correct term for an "old city" due to its direct etymological roots and specific historical context.
