Except: there aren't. Because Italians tend to still live in them and have gradually rebuilt them to fit the times. Refitting them back into ancient times and putting them back to how they used to be is massively expensive and bothersome for everyone involved, film crew and inhabitants alike.
And note I mention Italians, because those are the ones that might look like the ones you are after. You can't use a Bavarian village or the English countryside after all.
Depends entirely on whats in the contract.
