Even though there is no historical certainty, we have been led to believe that there was, in this exact territory, a small settlement (a hillfort) around the 5th century B.C. that would become Lamego.

Until the Roman colonization, many peoples settled around here: Iberians, Lusitanians, etc. It was under Roman rule that its agricultural products, and especially its wines, became famous in the whole Empire. After the Arab invasion (3rd century), that deeply marked the region, the city was historically shaken by a succession (over 4 centuries – 7th through 11th Century) of conquests by Christians and Arabs (the city was definitively recovered from the Moors in the 11th century).
