The chapter underlines the peculiarities of architectural, and it focuses on specific methodological aspects, in particular related to historical studies and their aims. Advanced digital models for historical buildings are based on the synergy of 3D-modeling and database-modeling. In particular, documentation, surveying, computer based-visualization, virtual reconstructions, digital archives, and digital museums, as well as gaming, edutainment, and e-tourism approaches favor the development and diffusion of non-linear, multi-directional, and media complex storytelling for heritage study, interpretation, presentation, and conservation.
