Abstract. The developments of the latest technology in the field of Digital Cultural Heritage (DCH) are revolutionizing the methods of surveying, representing and managing the built heritage. The integrated use of 3D survey instruments such as laser scanning, digital photogrammetry and the new holistic way to represent the architecture, based on the Building Information Modeling (BIM), allows the collection, analysis and archiving of a large amount of data, by increasing information sharing among a great number of experts involved during the life cycle of the building. The paper focuses on the connection between Italy and Czech in terms of vaults patterns and construction techniques. The two case studies are the frame vault of the chapel of the Italian Cultural Institute and the barrel vault with lunettes of the Klementinum Baroque Library. They are both unique examples of the great expertise of architects and craftsmen that worked in Bohemia across the 17th and 18th centuries. Most of them were from the North of Italy, like the ones that worked in the building sites of the two case studies. The in-depth study of the construction techniques and the complex shapes needs the use of new scan-to-BIM modeling requirements, based on the definition of geometric primitives useful for the generation of intelligent three-dimensional models able to integrate different types of data. Finally, the acquired data are included in a database that collects information coming from both Italian and Czech studies, raising awareness among citizens of the richness of their built heritage.
