Two seasons of archaeological survey, integrating geophysical and topographical techniques, were undertaken focussing on the area around the forum at Fregellae at the invitation of Professor Filippo Coarelli. This integrated survey has proved invaluable in understanding and interpreting the nature of the archaeological remains despite the problems of the natural geology and the insubstantial character of the structures. It is also clear that the distinctive local topography constrained the layout of the city. The central ridge provided the axis for the via Latina and acted as a focus for public buildings including the forum and comitium.

The magnetometer survey provided a reasonably clear depiction of the plans of both public and private buildings. Different depths of deposit that have accumulated on different parts of the site may obscure some ancient buildings but there are also likely to have been differences in preservation. As the magnetometer survey did successfully identify structures on the steep slopes of the western part of the plateau we are encouraged about its potential for the large scale mapping of the city.
