Britain being the exception, it seems rather difficult to find out the highest status of towns within the provinces of the Roman Empire. The Barrington Atlas, I've discovered, is a completely useless resource as it fails to attach a status to any settlement between village and town.

Can anyone help with these last five or any potential corrections?
GAUL
Gaul is one of the hardest provinces to research towns, and I'm almost ready to give up, as no maps seem to state--even from recent issues of the Gallia journal--Coloniae or Municipia status for any towns. Everything is simply given Civitas status, when I know this doesn't apply to all Gallic towns. Even more bizarre is the classification of Boulogne as a town! I know it was a naval base, but what evidence is there that it became a town?

Anyone read French? Does it mention anything about Boulogne being a town?
