Afonso I of Portugal
The majority of the settlements in Sabrosa date back to the Middle Ages, and were formalized in forals bestowed by hereditary heirs of Afonso I of Portugal. Many of these settlements were actually established prior to 1143 (the establishment of the Kingdom of Portugal), such as Provesende, and have scattered paleo-Christian structures from this period, as in the cases of Arcã, Vilar de Celas, Paredes, Provesende and Donelo.
