The Archaeological Park of Pompeii has completed the first comprehensive monitoring of the entire ancient city, with over 70,000 files pertaining to 13,000 rooms and 1,200 cadastral units such as dwellings, stores, and public areas. A interdisciplinary project completed in eight months by architects, engineers, restorers, and archaeologists, facilitated by a web application. The system digitally collects all data on the conservation status of walls, floors, roofs, frescoes, and mosaics, automatically identifying hazards and degradation. The information is transferred to a cartographic platform that enables the planning of ordinary and extraordinary maintenance over a three-year period and the implementation of timely interventions. The data analysis uncovers previously unknown relationships between various types of degradation, offering up new avenues for understanding deterioration dynamics and developing preventive treatments. The concept is intended to be long-term, reproducible, and capable of improving the site's utilization by gradually expanding the areas accessible to visitors. Pompeii is thus designed as an advanced protection laboratory, with regular maintenance, digital technologies, and scientific knowledge enabling innovative and methodical heritage management.
