revealed the following:
• A positive correlation between wall temperature and
height
• A negative correlation between wall humidity and height
• Anomalies in moss-covered or deteriorated areas,
where temperatures were lower and humidity
higher than in unaffected areas at the same height
(Figure 10).
Hydrogeology significantly influences the degradation
of heritage buildings by affecting the stability of their
foundations. Variations in the water table can lead to
soil liquefaction or foundation settlement, increasing
the risk of tilting or collapse. A high water table can also
result in capillary water absorption by building walls

stability and durability. Given these risks, it is imperative
