Long before Portugal became independent, the parish of Cidadelhe was a town called CIVITADELLA, destroyed in the year 134 BCE, by the troops of a Roman general.

In this same Castro, with the archaeological excavations carried out in 1983, Roman coins were found with the image of Emperor César Augusto.
Castro de Cidadelhe was a metallurgical settlement founded during the late bronze age, which was followed, after its destruction, by a new Castro occupation. This period must correspond to the construction of the outer walls, created by the primordial inhabitants, most likely, for defense against the invasions carried out by the enemy troops.
The Castro Céltico de Cidadelhe rises on top of a hill, in the vicinity of the town that gave it its name and whose foundation will be earlier than that of the town of Mesão Frio. In the area of the acropolis, a medieval quadrangular tower dating from the 10th century was implanted.
The Romans left marks of their presence in this parish, namely, a section of sidewalk and the Ponte dos Martinhos. Passed here, the Roman military route that went from Braga to Amarante.
