The Church appropriated the historical zone of the Celto-Roman settlement, erecting a stone church, while the fishermen expropriated Sarrazola (or Terra dos Salgueiros, known as the lands of the salters) to shelter their fishing community. Consequently, the new settlement of Cacia was established south of the primitive colony, while smaller agglomerations began to grow in the vicinity: to the south, Quintã do Loureiro, and farther to the west of Sarrazola, the villages of Vilarinho and Póvoa (along the sea).
