The mapping of buried targets without having access directly above them, such as the buildings foundations, using geophysical methods, is quite a challenging task. This work presents the geophysical results from the mapping of Neoria (Venetian dockyards) foundations in Chania, Greece, using 2D and 3D Electrical Resistivity Tomography (ERT), Seismic Refraction Tomography (SRT) and Ground Penetrating Radar (GPR) methods, under the framework of a project for the restoration and rehabilitation of these Venetian monuments. The space accessibility allowed the deployment of the surveyed lines mostly parallel and limited perpendicular to the walls. High seismic velocity and electrical resistivity values, depicted in SRT and ERT sections respectively, directly below Neoria walls, are attributed to their foundations, which extend to a depth of approximately 3m. ERT and GPR sections indicate that the foundations do not exhibit remarkable lateral extent. SRT sections showed that foundations probably are based on the rocky substratum of the surveyed area.
