No, but I was thinking major towns. So for example, starting with south Italy:

Syracuse,
Messana,
Lilybaeum,
Panormus,
Rhegium,
Croton,
Thurii,
Tarentum,
Brundisium,
Venusia,
Heraclea,
Paestum,
Buxentum,
Capua,
Beneventum,
Luceria,
Aquilonia... I could go on but you get the idea.

Obviously I don't expect to find them all, but the truth is that probably all ancient wall lines are known to some degree or other. I couldn't find a book that collects them together though.
