Professional experience and contact with experts reveal a pressing problem in the field of knowledge and management of architectural heritage: the tendency to scatter the information obtained from the different areas -administration, scientific community and professionals of architecture- and disciplines involved -archaeologists, historians, architects, etc.-, causing serious problems of data loss or duplication. That reality has produced lack of efficiency in planning and implementing the various activities of maintenance and intervention in these architectures, as well as wastage of important investigative work. Such circumstances obstruct disclosure and, therefore, knowledge of heritage. As a possible solution to that problem, this article describes an experience that aims to lay the groundwork for building a tool that, based on computer models, is able to contain and manage the information generated about a historical monument, facilitating cross-cutting relationships between different analysis that address the knowledge of the building. In this case, the analysis of the construction and conservation of one of the buildings of the archaeological site of Italica forms the data base of this tool still in gestation, thus establishing the basic knowledge for its management and conservation.
