In the field of Cultural Heritage there are many Serious Games applications.
3D models of cultural heritage objects created with 3D modelling methods preserving realism and detail can be a very useful tool for Serious Games if exploited correctly and suitably.
In this paper a composite SG application is developed and presented using such realistic 3D models produced by Geomatics techniques. The construction of these 3D models is presented along with the application, which consists of
three different options for the user: A virtual navigation to the
site with some questions, a visit to the museum of a monument
and an educational quiz game concerning the architectural
reconstruction of this monument.
