In the years 2014-2016, as part of the of the fieldwork campaigns of geophysical prospection, systematic surface collections and trial trenches undertaken by the S’Urachi Project in the wider are of the nuraghe of S’Urachi (see site #3372), the site of Su Padrigheddu was also investigated.

In 2014, georadar and magnetic prospections recorded a number of substantial anomalies around the NE corner of the Su Padrigheddu eucalyptus trees, which more or less coincided with the likely edge of occupation around S’Urachi. Systematic sampling of surface finds in 2015 yielded substantial quantities of pottery in the same area along the tree stand, including unambiguous Nuragic pottery fragments of Iron Age date, including askos and decorated fragments. In 2016, a 1.5×1.5 trial trench dug at the NE corner of the tree stand yielded a very large and remarkably coherent collection of pottery and animal bone, which ranged from the Nuragic Final Bronze and Iron Ages to the Phoenician and Punic periods – but without stratigraphic coherence, as no stratigraphically intact deposits were encountered. Deep-ploughing of the area in the 1970s to prepare the planting of the eucalyptus trees had clearly comprehensively destroyed all archaeological deposits.
