Ancient Rome - Third Samnite War 298 bce

Portus Cosanus was the harbor for the settlement of Cosa, supporting military and trade ships. It served as an important maritime access point for Rome’s interests along the Tyrrhenian coast, enhancing Rome’s ability to supply and communicate with its settlements along the coast, crucial for maintaining territorial control over Etruria. During 298 BCE, it is likely in development, as the port’s construction began alongside the settlement of Cosa.

Bustling port with wooden docks lined with vessels, merchants shouting and trading wares, the sun glinting off the waves, and distant hills framing the harbor under a vibrant sky.
