In June/July 2006 and November 2007 geophysical survey was undertaken at the site of Roman town of Calatia by a joint team from the British School at Rome and the Archaeological Prospection Services of Southampton (APSS). The work was funded by and conducted on behalf of the Comune di Maddaloni.

Both magnetometry and resistivity techniques have been successful in detecting major anomalies such as roads and large walls but each has failed to identify more detailed traces of the internal layout and form of the town. This survey has highlighted the advantages of using two methods as they can compliment each other and it is easier to evaluate the integrity of the results.

A number of roads were detected in the magnetometer survey. The alignment of the decumanus and cardines clearly compliment the traces of roads identified in the previous season’s results (Hay 2006: 11) and the overall grid system applied in the town. Once again, there is a paucity of internal structures relating to these routeways.

The integration of the resistivity survey certainly confirms the presence of these roads, represented as areas of high resistance in the results. Critically, the course of the town wall was identified in the northern part of the survey area. As a direct result of applying and integrated survey methodology a trace of the northern part of the town’s circuit wall was detected.
