The Hyblaean Archaelogical Landscapes Survey Project (Ragusa, Italy). Preventive archaeology and non-in- vasive investigation methods for research on the ancient landscapes of Sicily - The paper presents the results of the Hyblaean Archaelogical Landscapes Survey Project, carried out in southeastern Sicily (Italy). Located in a focal point of the Mediterranean region, the area forms a perfect case for research on settlement and routes networks in a diachronic perspective. Project’s first stage was carried out through the application of a spectrum of methods within preventive archaeology activities: the integrated use of the ‘traditional’ field sur- vey with remote and proximal sensing and micro- to large-scale geophysical prospection (i.e. extensive use of seismic refraction and geomagnetic survey; intensive use of ground penetrating radar and electrical resistivity tomography) was designed for a new understanding of the Hyblaean territory, moving from an essentially site-based approach to a landscape-scale perspective.
