Abstract

We often come across a problem of deterioration in some 15th and 16th century mural painting (MP) ensembles on the inner walls of granitic Romanesque religious buildings in the north of Portugal (fig. 1). It is manifested by the presence of dark pigmentation staining both granite supports and mural paintings (Marco, 2016 and 2019). The origin of this phenomenon is unknown and may be due to synergy of factors such as microbiological and chemical attacks.
