Between 12th July 2006 and 10th August 2007 a geophysical survey was undertaken at the site of Riva di Roma close to the town of Acilia Madonetta, 20km to the south west of Rome in the Comune di Roma. The survey was conducted to assess the archaeological potential of an area of terrain some 135 hectares in size, located between the low hills of Acilia to the north east, and the coastal plain of Casal Palocco to the south west. The work was carried out on behalf of SIACI for Pirelli RE – Aree Urbane, and was conducted by the British School at Rome and the University of Southampton. The survey was successful in mapping and identifying a number of archaeological features across the area, mainly relating to the works of the Bonifica conducted along the coastal plain in the 19th and 20th centuries. Remnants of some military and telecommunications infrastructure were also identified in the survey results, but no extensive evidence was found to suggest significant human habitation in the area in the prehistoric, Roman and medieval periods.
