This paper investigates a set of interrelated key elements that take part in the development of ICT systems for Cultural Heritage (CH). The main objective is to promote the integrated knowledge of CH within its context, so that it becomes a factor of growth in the cultural, social, and economic system, in specific geographic areas. The set of skills developed during several years, the expertise and the innovative tools with wich the Technical Unit for IT and ICT Systems Developments (ENEA-UTICT) provides the CH sector are presented. In particular, some experiences concerning the process which incorporates specific methodologies and technologies are shown. The ICT platform for CH implemented at ENEA-UTICT and the development of applications based on Artificial Intelligence for the semantic fruition of cultural information are here described.

The paper describes a multidisciplinary and integrated methodology related to material and structural elements tests, Laser Scanner surveys and Remote Sensing technology, applied to Historical Heritage. The knowledge process was aimed at defining the rehabilitation project of an historic building in Caporciano, a small old town centre damaged by the Abruzzo (Italy) earthquake which occurred on April 6th, 2009.
The building analyzed is characterized by an extremely complex morphology, developed on different levels and making surveys using traditional methods particularly difficult. Therefore the laser scanning technique, which provides a complete 3D model of the entire structure, has been used.
Due to the effects of the earthquake, the testing of the building’s structure had to take several aspects into consideration. An extensive non-destructive and semi-destructive tests campaign has been performed, in order to obtain historical-architectural knowledge and in situ materials characterization. The main techniques used were thermograph, ground penetrating radar, endoscopy, masonry analysis and mortar penetration test.
In this case study, UAV remote sensing was employed, to collect data thanks to sensors mounted on carriers operating at low altitude. I was able to survey the roofs of the buildings: captured images were processed to identify any damage even on inaccessible areas.

La tutela del patrimonio architettonico ha inizio nel momento di riconoscimento delle sue molteplici valenze, condivise dalla collettività ed esplicitate dalle azioni di restauro e salvaguardia messe in atto.
La redazione di un progetto di restauro porta con se la responsabilità di soddisfare sia le istanze di conservazione e valorizzazione del costruito storico, sia le istanze statiche e di sicurezza per la fruizione degli edifici.
A tale scopo diventa fondamentale intraprendere un processo metodologico di conoscenza dei caratteri semantici e materici di un edificio, a partire dalla sua storia costruttiva per arrivare alle caratteristiche fisico-meccaniche dei materiali utilizzati.
Delineare il profilo storico, consultando biblioteche e archivi; tracciare le fasi costruttive attraverso l’analisi stratigrafica degli elevati; pianificare e coordinare i rilievi geometrici e architettonici utilizzando metodi tradizionali e
strumentazione di alto profilo tecnologico; individuare e classificare alterazioni e caratteristiche della pietra e dei materiali del cantiere tradizionale; redigere un programma di indagini tecnico-scientifiche per favorire il rilievo materico, l’analisi del degrado e per definire le caratteristiche meccaniche degli elementi strutturali. Questi sono alcuni degli argomenti affrontati nel presente testo, che possono considerarsi parte integrante del percorso di conoscenza dell’architettura storica.
