The ancient settlement of Piammiano-Statonia (Bomarzo, Italy): New data from 2D and 3D electrical tomography

This study presents new archaeological data concerning the ancient layout ofPiammiano, an Etruscan and Roman settlement located in the Tiberine internal Etruria(probably corresponding to the ancient town of Statonia), still little known. Thesedata have been obtained by geophysical surveys performed using the Electrical ResistivityTomography technique. These investigations were carried out in the centralsector of the plateau where the settlement lies, and they have documented thepresence of ancient buried structures at a depth of between about 0.5 and 2.5 m.These structures has the same orientation of the main road of the ancient settlement,and they are also consistent with the orientation of the structures documented inprevious geophysical surveys and archaeological excavations carried out in the westernmostsector of the investigated area. Specifically, the new geophysical surveyshave highlighted the presence of the buried remains of the road and numerous walls,some of which are pertaining to a large building with porticoes on the two sides overlookingthe Tiber valley. Furthermore, a channel network perhaps linked to a cisternwas documented at more depth.
