This study is aimed at investigating the vulnerability of the underground sites and its relationship with the relevant environmental and microenvironmental conditions, focusing on the properties and deterioration of the rock those caves are excavated into. The eventual outcomes are expected to support the adoption of countermeasures for preserving and promoting those sites and the stone artifacts enshrined therein, and give indications about the influence and safety of visitor traffic.

Here we introduce the first results of the characterization 223of the textural, mineralogical, petrophysical, and chemical properties of the rock and its alteration products, reserving particular attention to salt weathering and rock-water interaction. The principal techniques applied were optical microscopy, scanning electron microscope, X-ray powder diffraction, X-ray fluorescence, and mercury intrusion porosimetry. These were combined with the long-term monitoring of air temperature and relative humidity (RH).
