Non invasive multi-technique analysis of historical architecture for monitoring and conservation purposes

The mobile laboratory MOLAB, European infrastructure of the CHARISMA project, avails of numerous portable instruments that exploit the use of non invasive techniques and supply information concerning the elementary and molecular composition of surfaces of historical architecture. Some case studies carried on monuments of national interest (the portal of Palazzo dei Priori in Perugia) and of international interest (in Spain the portal of the Cathedral of Santiago de Compostela) will be reported to demonstrate the analytical potentiality of the integrated approach of non invasive techniques.
