Viana do Castelo, born from the will of D. Afonso III, bringing together the necessary conditions of security and legislation so that the inhabitants of this region who used to live in rustic and scattered villas could develop their maritime activities in an organized urban environment.

We continue the visit through Viana do Castelo, now through streets with urban manor houses, some from the 17th century, others from the 17th century, and some old monasteries. The Viana of the century. XVII is related to the cycle of Brazilian sugar that extends until 1660. Period of intense activity on the docks: establishment of foreign trade (families of Dutch, Flemish, French traders, are based in Viana). From Brazilian ports (Rio de Janeiro, Ilhéus, Pernambuco, Olinda and Recife) an appreciable volume of Brazilian sugar production comes, increasing the movement with ports in northern Europe (Rouen, Antwerp, Amsterdam, Hamburg, etc.). Between 1566-1660 about 25% of Brazilian production is transported by ships from Viana.
