• The City of Alet is an important archaeological site in Brittany because it was in the late Iron Age the capital of theCoriosolites. The remains, scattered today in a neighbourhood of Saint-Malo, are highly heterogeneous. Because of itsgreat archeological interest, it has become since 2015 the subject of experimentation in digital archeology. From 3Dscanning and Ground Penetrating Radar experimentation, we started a 3D reconstruction of city including several levelsof uncertainty and fuelling archaeological thoughts, the results of which are still in discussion.
