Editing Valongo (section)

===Ancient history===
This region was occupied by the [[Roman Empire|Romans]], especially for gold mining in the Serra de Santa Justa. One of the traces of Roman occupation is in the municipality name, which originated in the Latin words ''Vallis Longus''. There are still traces that would allow the detection of two main Roman connecting roads that would cross the municipality: the [[Porto]] - [[Guimarães]] road and the [[Alfena]] - Valongo - Aguiar de Sousa / [[Penafiel]] road.<ref name=":0" />

This region would then be occupied by the germanic [[Kingdom of the Suebi|Suebi]] and [[Visigothic Kingdom|Visigoths]] and later by Arabs and [[Moors]]. Toponyms in the municipality from this period include "Luriz" of [[Germanic languages|germanic]] origin and “Moirama”, “Ilhar Mourisco” and “Alfena” from [[Arabic]] origin.<ref name=":0" />

According to Father Lopes dos Reis, a native of Valongo, “the Moors entered Hespanha enthusiastic about the holy war with the alfange in one hand and [[Al Koran]] in the other, taking over with their powerful army all the places they could pass through. In Vallongo, perhaps there was no blood at all, because the inhabitants, few and without defense, could only fearlessly try to prevent the passage to a powerful enemy from whom they had known that an army of brave people had fled in terror. That is why, when the Arabs arrived in Vallongo (716), they left their people in peace without writing it, and by means of a certain tribute they gave them the freedom to live as they did here, going to settle far from the Goda settlement, which occupied the Susão and the western part of the villa, on the plain at the edge of a stream that was later called Ilhar Mourisco.”<ref>{{Cite book|last=Ferreira|first=Nuno|title=Igreja Matriz de Sobrado- O Segredo da Memória, Edição de Autor|publisher=Valongo|year=2016}}</ref>

After the ''[[Reconquista|reconquest]]'' of ''Portus Cale'' ([[Porto]]) by [[Vímara Peres]] in 868, he was named a count and given control of the [[March (territory)|frontier region]] between the [[Lima River|Lima]] and [[Douro]] rivers by [[Alfonso III of Asturias]], therefore bringing the region under control of the [[Kingdom of Asturias]].{{Citation needed|date=December 2024}}
