The management of archaeological sites has always been a particularly complex issue, especially in the context of significant natural and man-made hazards. Among these, climate change is becoming increasingly significant. Over the past few decades, the analysis of the evolution of the condition of archaeological sites has revealed a trend of decay that is significantly influenced by extreme and/or rapid weather changes. While short-term solutions may not always be available to prevent disasters, proactive maintenance can help to control the impact caused by rapid changes and mitigate their extreme effects. Therefore, reliable knowledge and prediction of the evolution of decay are key to the design of a successful maintenance plan.In this context, an innovative approach to monitoring has been developed and applied in the Archaeological Park of Pompeii (Southern Italy). The methodology adopts both multi-scale (data and time resolution) and multi-level (assessment accuracy) approaches compatible with the master data and the information system already developed and implemented in the Park. This paper outlines the overall monitoring framework, which is structured on three assessment levels: Local (LA), General (GA) and Detailed (DA). Additionally, some application examples are also described.
