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.
