Tergeste, under Roman control from 177 BCE,…

Tergeste, under Roman control from 177 BCE, had been granted the status of colony under Julius Caesar, who recorded its name as Tergeste in his Commentarii de bello Gallico (51 BCE).

During Roman times, Tergeste is defined an "Illyrian city" by Artemidorus of Ephesus, a Greek geographer, and "Carnic" by Strabo.

The border of "Roman Italia" has moved from the Timavo river to Formione (today Risano).

The Roman Tergeste flourishes due to its position as a crossroad from Aquileia, the main Roman city in the area, and Istria, and as a port as well, some ruins of which are still visible.

Octavian builds a line of walls around the city in 33-32 BCE, and supervises the construction of harbor facilities.
