Editing Valongo (section)

===Middle ages===
From the [[Inquirições|General Inquiries]] of 1258, the current municipality was divided at the time between the jurisdiction (julgado) of [[Aguiar de Sousa]] - which included S. Martinho de Campo and Sobrado, and the jurisdiction of [[Maia, Portugal|Maia]], which included S. Vicente da Queimadela, Valongo and S. Lourenço de Asmes.<ref name=":0" />

From the economic and social point of view, at this time, the ownership of land was the basis of the economy and the main element of survival and power. In the area of the municipality, land belonged to the [[King]] and the [[Clergy]] - particularly the [[Regular clergy|Regular Clergy.]]<ref name=":0" />

The appearance of new settlements, the progressive extension of the term of existing settlements, the multiplication of suffragan chapels and the division of property, is evidence of the notorious demographic growth of this region over the centuries. This increase in population was accompanied by the progressive development of other sectors of the economy. Industry and commerce, initially based on incipient forms, acquire a strong expression in the economy. The traditional bakery industry is an excellent example of this: its origins date back to the Low Middle Ages, but the development of wheat bread is such a development, which allowed Valongo bakers to feed the entire surrounding region and with the product of their work. This, in turn, allows them to make a decisive contribution. for the construction of the new church, the Igreja Matriz de Valongo, whose construction dates to the end of the 18th century.<ref name=":0" />
