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