ABSTRACT
This paper is dedicated to highlight the importance of monitoring to determine a diagnosis. Two case studies are presented. The former case deals with the Benedictine Basilica of S. Angelo in Formis constructed in the XI century. It contains an outstanding cycle of medieval frescoes. Monitoring was carried out with the combined use of terrestrial survey and of satellite data. The Incurabili complex in Napoli with its Pharmacy (XVI – XVIII century) is the second case presented in the paper. The rooms of the Pharmacy with its paintings, its ceramics and its decorated floor is a marvelous monument located in the historical center of the ancient greek Neapolis. In this case movements were detected too and a monitoring plan was organized and carried out. The diagnosis was easier than in the first case and the remedial works have been fully designed.
