The sanctuary of the Acropolis of Athens in Greece provided one of the first monumental bronze statues some 2500 yearsago, whichwas dedicated to the goddess Athena.Duringrecent decades, important understanding ofthe statue's manufacturing processes has been achieved byarchaeological studies, and the former production site has been identified on the southern slope of the Acropolis.Two major bronze production pits have been detected and one was excavated in 2001 and 2006 and was found in an unexpected location. Therefore, in 2010 a geophysical survey of the wholeproduction sitewascarried out for the first timeinorder to eitherrevealor to excludeany further sitesofthebronze foundry complex. A combination of different geophysical methods was applied to survey the subsurface; magnetometry (MAG), two-and three-dimensional electrical resistivity tomography (ERT), as well as two-and three-dimensional ground-penetrating radar (GPR).Two major anomalies have been identified in the processed data, which provide evidence foradditionalproduction sites.One was a known siteidentifiedin a test trenchin 2001, and our surveyhas outlined the extent of the former pit. The other anomaly, which was detected by ERT and GPR, was 8^10 m in length and 23 m in width and is oval-shaped and about 2.5 m deep. Steep vertical walls, together with two narrow points at the ends ofthe pit, which could reflect formerentrances, were identified.Virtual ERTand GPR models generated from cross-sections ofa ground-based LiDAR scan of the 2001and 2006 excavated pit helped to interpret and understand the geophysical data of anomaly 2. This anomaly was finally interpreted as a newly detected production pit of the bronze foundry complex, and based on these findings new excavations are planned.
