I love those finds! Something draws on me, hard. That looks like an outpost rather than a city. They need to sound/radar the surrounding area, for sure.
The largest Roman-era city in Illyria (Scodra) had perhaps 50K people in it. Most classical-era towns with a Roman grid layout covered more ground that was warranted by their initial population, while those antedating Roman conquest had just grown up willy-nilly, and were constrained by things like water supply and waste disposal, and by their surrounding ag footprint.
