Here we are at the mouth of the Rio Sabor, which is a tributary of the Douro River. It is the parish Cabeça Boa, with 428 inhabitants, which is located between mountains and overlooks the valley of Vilariça and the Douro River, in the extreme west of the municipality. The settlement of this place dates back to prehistoric times. It has 4 attached places: Cabeça de Mouro, Cabanas de Cima, Cabanas de Baixo and Foz do Sabor.

In this village, the traditional buildings of Cabeça Boa should be highlighted. Equally interesting are the Matriz Church of Cabeça Boa, the chapel of Santa Catarina and the chapel of Nossa Senhora do Rosário.
