 One of the vestiges of this period was the use of soft limestone (from the region of Coimbra), a fact that contrasts with the widespread use of granite in later public works.In the 11th century construction campaign that followed, supported and consecrated in 1087 by the Bishop of Braga (D. Pedro), included the lower areas of the chancel, whose blind arcades were constructed in a more archaic style.The truly Romanesque phase actually began late, around the 13th century.
