The occupation of this region continued throughout the medieval period, especially on the hilltop of Castelo de Matos. It strengthens the scenery and is an important part of Baião’s identity, as the place chosen by the territory’s lord to build a castle in mid-11th Century to handle the affairs of “Bayam”. It was a wooden fortress, later ruined by a fire. It was in its ashes that a knight’s spur was found – a unique artifact of the Christian reconquest.
