Portuguese Translation Services in Oporto


Oporto’s economic relations with the Douro Valley have been well documented since the Middle Ages. Walnuts, dried fruits and olive oil have sustained a flourishing trade between Oporto and the region.

These products were exported from Oporto to foreign markets in the Old and New World. However, the major drive towards the development of interregional business dealings derived from the agro-industry of Port wine.

This activity had a decisive impact on the development of the mutually beneficial relationship between the major urban centre of the coast and this region of huge agricultural potential, particularly geared towards the production of high-quality fortified wines.

Oporto’s development was always closely linked with the south bank of the Douro river, Vila Nova de Gaia, an integral part of its municipality until 1834, where the cellars for aging the fine wines of the Upper Douro were set up.
