Cividale del Friuli
The Julian Alps were known in antiquity as "Alpe Iulia", and also attested as "Alpes Juliana" AD 670, "Alpis Julia" 734, and "Alpes Iulias" in 1090. Like the municipium of "Forum Julii" (now Cividale del Friuli) at the foot of the mountains, the range was named after Julius Caesar of the Julian clan, perhaps due to a road built by Julius Caesar and completed by Augustus.
