大ドルスス
The modern-day Bolzano was in ancient times a marshy region inhabited by the Raetian Isarci people, traditionally believed to be descendants of Etruscan refugees fleeing Italy from the invading Gauls. The Romans built a settlement after the area had been conquered in 15 BC by General Nero Claudius Drusus. The military settlement, "Pons Drusi" (Drusus Bridge), was named after this Roman General. During this time the area became part of the region Venetia et Histria (Regio X) of ancient Italy.
