Between January and February 2003 a geophysical survey was undertaken of an area equalling circa seven hectares of the site partly occupied by the sanctuary. Entire quarters of the town were identified, confirming that it was densely occupied right up to the sanctuary, separated by a road, with monumental structures of great visual impact. In particular an elliptical arena was identified (longest axis 45 m), which may have belonged to an amphitheatre, or to a ludus, considering that an amphitheatre is already known at Teano on the western slope of the hill of Villino S. Antonio. The structure could also be identified as a market, a sort of forum Boarium, whose position in the eastern zone of the town, not far from the road going east to Allifae and the Apennines, would seem rather appropriate. Situated on the long axis of the elliptical arena was an enclosure with a building that may be interpreted as a temple. At least one other monumental building and a cistern complete the picture produced by a non-destructive and exceptionally productive analysis which also provided many starting points for further research.
