This paper deals with the survey and communications of Cultural Heritage through the development of innovative methodologies.
The case of study is the polychrome wooden ceiling in the \u201cMagna\u201d Hall of \u201cPalazzo Steri\u201d. The \u201cSteri\u201d, built in the XIVth century by the noble family Chiaromonte, is at the present the headquarter of the Rector\u2019s Office of Palermo University. A 3D model of the wooden ceiling has initially been carried out with laser-scanning and digital photogrammetric techniques; successively a multimodal interactive guide has been realized. The guide is integrated to the 3D model, so that visitors can navigate the virtual representation of
the ancient wood ceiling and achieve, interacting vocally, relevant meta information about history and sense of painted scenes
