We are assisting today to the increased need of web-based Integrated solutions in and for Cultural Heritage. This presentation will offer a national overview on the different activities in the field of Cultural Heritage that are increasingly requiring the use of the network, from the design of interactive media to field acquisition (i.e. in archaeological sites), from data analysis and simulation to 3d model semantic annotation, from collaboration in virtual environments to web3d applications for museums and monuments. Example of recent tools, services and applications will be provided (as for Aton, Emviq, 3D Hop and Movida). The challenges and potentialities offered by infrastructural projects such as ERIHS will be set as the turning point that will lead, in the next decade, to new Data Spaces, CH research National Cloud and CH Italian digital library.
