The earliest settlement of the area can be dated to the Iron Age, around the 10th century BC.

From the mid-9th century BC the Veneti occupied site and gave it its name.
 Etymologically, "-terg-" in Opitergium stems from a Venetic root word indicating a market (q.v.
Tergeste, the old name of Trieste).
 The location of Oderzo on the Venetian plain and between the Monticano and Navisego rivers made it ideal as a center for trade.
