The work was carried out at the request of Ing. Salvatore Constanzo of the Comune di Sant’Arpino in association with the Soprintendenza per i beni archeologici di Caserta e Benevento, in particular Dott.ssa Elena Laforgia who wished to undertake a geophysical survey for investigating the archaeological potential of the site. It was undertaken by a joint team from the Archaeological Prospection Services of Southampton (APSS) and the British School at Rome. The survey was carried out to determine the potential for archaeological remains on a site due for development. To increase the potential for a variety of archaeological remains being detected, it was decided to integrate both a magnetometer and resistivity survey. The integration of both geophysical techniques on this small site has proved to be extremely useful both in terms of defining different buried features and providing more information as to the nature of the remains appearing in both surveys. The most important feature identified in both surveys lies in the central section of the survey area. The linear anomalies clearly trace the standing remains of the boundary wall associated with the market area of the Casale. Interestingly, each technique detected the smaller walls adjoining the main boundary but in different areas along the course of the wall. Although this wall can be seen exposed in part in the field, the combination of both geophysical methodologies has expanded our understanding as to the form and layout of the surviving archaeological remains. Apart from the main boundary wall, no other features of archaeological potential are apparent in the rest of the survey.
