An advanced diagnostic plan applied to a significant national monument: the Royal Palace in Naples

To achieve adequate restoration project, the phase of choice the type of intervention it's a very delicate step that necessarily involves a thorough understanding of the asset in all its aspects, such as the location, the history, the architecture, the state of preservation, the signs of deterioration, the materials analysis and their degradation. The set of all that it's possible investigate on a product (cultural), the obtaining of important informations for subsequent maintenance actions, the conservation and/or restoration, is what is called a diagnostic plan. The significance of this work reside to consider a monument of national importance, the Royal Palace in Naples, on which apply a diagnostic plan. The science is an useful completion of the diagnostic field and this is why it's flanked now in this study; it provides in situ observations and laboratory measurements using advanced microscopic technologies (Scanning Electron Microscopy SEM/EDS for morphological and chemical studies at micrometric scale) on samples taken directly near the Palace. The final results have allowed the creation of a series of analytical cards containing digital data required to detect future intervention actions.
