Early urbanization at Crustumerium (Rome, Italy) between the 9th and 5th B.C.

This paper provides an introduction to the protohistoric Latial hillsite of Crustumerium (ca. 15 km north/notheast of Rome along the via Salaria in the Tiber valley) and an overview of different types of research on Crustumerium's urban phases, illustrating the potential of combining old and new data in an GIS environment. The application of large-scale geophysical surverys has marked an important methodological advance in the study of Crustumerium, such work being instrumental for assessing both the quantity and the quality of surviving archaeological sub-surfaces. The geophysical program has already employed magnetometry to bring to light new information on surviving structural features while at the same time confirming the strong effects of erosion at the site.
