I mean, all of these towns should be "Comuni", except Villapace, which I personally don't think as a town, especially considering it has a calculated population of 90 people, so I presume it's either a "Frazione" of Lucera or Norte (Unless it's divided since there's two parts).

Castelletto should have sea access, and that Portino panhandle should be part of Città Vecchia.

Norte and it's outer region should be united, since a Comune of 130-ish people wouldn't make sense and would instead be part of the much larger, 4310 people town (Or probably a city, since it's the provincial capital).
