In May 2002 a trial geophysical survey was undertaken on the behalf of Professor Filippo Coarelli of the University of Perugia and Dr Helen Patterson of the British School at Rome. The aim of the survey was to record any subsurface features associated with the site of a possible sanctuary, mentioned by Pliny, lying alongside the ancient via Flaminia. A resistivity survey was undertaken of an area of approximately 0.5 hectares, delimited by the confines of the modern park. The survey, whilst affected by the landscaping of the site, recorded a number of linear features close to the projected line of the ancient road. The survey, whilst indicating some activity, could not provide any details as to the chronology of these features. Subsequently a series of trial trenches were excavated by the University of Perugia (Dott.ssa Francesca Diosonno) across these geophysical anomalies, which were unable to reveal any traces of the possible site.
