Abstract


The main factors of deterioration that affect the Cathedral of Baeza are of a natural origin, basically thermic and hydraulic. Two types of calcarenite were employed in the construction of the major part of this building: one 'franca" of medium porosity and another "viva" harder and more compact, both extracted from the quarries in the area. The most frequent mechanisms of deterioration are those bound to crystallization-dissolution and hydration-dehydration of salts, as well as freezing inside the pores. Façade-by-façade description of the deterioration indicators is provided; the most common ones tend to be fissures, grain disgregations and disjunctions.
