Aquileia is the eastern terminus of the Via Postumia. The location greatly favoured trade, thanks to the river port, the channeling works that connected it to the nearby lagoon and the dense network of roads. It served as a point of arrival and sorting centre for the Po regions and across the Alps for goods imported from the Orient and later from Africa. For this reason, its wealth came from trade, but also from manufacturing activities. It is characterised by a dense network of routes connecting the main roads that converge here, like the Via Postumia which led to Genoa and Piacenza, and the Via Emilia which led to Rome via the Via Flaminia; the Via Popillia-Annia (from Ariminum, Rimini), the continuation to Emona (Ljubljana) of the Postumia, the road to Tergeste (Trieste) and Istria, and another towards Noricum (in what is now part of Austria and Slovenia)
