ABSTRACT
In the framework of the Santiago of Compostela Cathedral program, a multidisciplinary
investigation of the porch of the glory was carried out between 2009 and 2011
to identify the main environmental risks and to develop a preventive
conservation planto be integrated in the general management strategy of the
Cathedral. The study included historic
and archivist research, structural studies, mineralogical analyses, biological
sampling, cleaning tests and microclimatic monitoring.
The main weathering factors and the related damage processes were identified.
Results have shown that the main responsible for the observed damage was the
infiltration of rainwater through the roof, due to cracks in the structure of
the Cathedral. Other environmental factors having a remarkable impact on the
state of conservation of the polychrome and its substrate were the solar
radiation, the thermo-hygrometric cycles, the particle deposition and the
biological growth. Solutions were suggested to improve the environmental
conditions, thus reducing further damage.
KEYWORDS
