Outeiro Seco is a village that belongs to the municipality of Chaves situated in the north of Portugal. Due to the discovery of remains of a grape press, gold mines and homes, we can deduce that Roman settlements dominated the area. In the church of Nuestra Señora del Rosario, there is a Roman inscription that warned of the presence of some indigenous divinities. In the immediate surroundings the fort of Santa Ana is also found.
The Romanesque church of Nuestra Señora da Azinheira (Our lady of the Holm Oak) is located in Outeiro. It is a small building from the Late Romanesque period probably from the 13th century. Even though it has been reformed, it still conserves its medieval essence.
Other religious buildings also located in Outeiro Seco like the already mentioned Nuestra Señora del Rosario, are the Church of Santa Ana, the Church of Nuestra Señora de Portela and the Church of Saint Michael Archangel from the 16th century.
At the entrance of the village, there are small sanctuaries where it is still customary to leave keepsakes and donations. On the outskirts of the village you can see the sacred route and the monumental stone cross.
It is important to mention the house of the Montalvão family from the 18th century currently in ruins. It was built for the Portuguese nobility and is linked to the historical evolution of the village.
