Despite the poor state of conservation and corresponding asset value, little castle of Nóbrega has great historical significance and regional scientific interest enough for understanding the Organization and evolution of medieval settlement in the Minho region.

This castle has a rectangular plan and initially it was reinforced by eight semicircular towers with square plan keep. It is placed on a hill at 45 metres high from where it is possible to see São Martinho do Porto Bay.

Occupied by the Romans in the mid-2nd century, it was transformed into a political and administrative center, conquered by the Moors in 713 and taken over by the Portuguese crown in 1248. The castle was restored by Dom Dinis. The walls are made of rammed earth with battlements and a walkway that communicates with the watchtower. Traces of sections of the wall, the entrance turret and, inside, the ruins of a church with Gothic and Manueline traces remain.

Salir might have been the place where D. Paio Peres Correia awaited the arrival of D. Afonso III, so that together they could undertake the conquest of what remained in the province in the hands of the Moors. During the time of King Afonso III, this location became a stronghold, giving the castle a privileged role in the definitive conquest of the Algarve. It is presumed that the castle was burned down and rebuilt twice, and today only ruins of its walls remain.

This 15th-century monument is currently in ruins. Highlights include a sign with a poem by Engineer Mário Cruzeiro.
