    In this paper combination of advanced experimental and numerical methods for micromechanical
    and microstructural characterization of natural stones used in historical buildings is
    presented. Several different types of porous stones commonly used for construction of built
    heritage as well as for restoration purposes were subjected to complex experimental investigation
    involving SEM imaging, EDS based identification of chemical composition, nanomechanical
    measurement of properties of constituent phase and experimental measurements
    of fluid uptake characteristics. Using a combination of image and signal processing techniques
    applied on SEM micrographs dimensions of representative volume element of investigated
    materials were determined. Real-time X-ray radiography utilizing state-of-the-art
    dual source/dual energy setup was used for observation of fluid penetration process in Maastricht
    limestone and to develop a detailed voxel model for numerical simulations of investigated
    phenomena. Using such methods methodology for description of important factors influencing
    sustainability of historical buildings was established.
