Geophysical Investigations at the Artemision at Amarynthos of Euboea (Greece)

A combination of resistivity mapping and three‐dimensional electrical resistivity tomography (ERT) was used to investigate the subsurface of the sanctuary of Artemis Amarysia in Amarynthos, Euboea (Greece), an area where archaeological remains from the Bronze Age to the post‐Byzantine period are preserved. The survey strategy was tailored to the site‐specific conditions—such as modern infrastructure and ground conditions—and prioritized electrical methods over magnetometry and ground penetrating radar (GPR). High‐resolution 2D and 3D resistivity models revealed significant subsurface anomalies, many of which formed linear and rectilinear patterns that were interpreted as buried architectural features. Several of these features were aligned with structures previously uncovered by excavation. Subsequent archaeological investigations verified the geophysical interpretations and confirmed the presence, alignment and extent of several anomalies. These results illustrate the effectiveness of ERT in detecting architectural remains under complex site conditions and confirm its value in guiding excavation work. Although much of the site has been excavated and investigated, many areas remain unexplored. Given the demonstrated correlation between resistivity anomalies and subsurface structures, it is likely that similar features are present in the unexcavated areas. In this context, geophysical imaging can be viewed as a dynamic interpretive tool—one whose significance may evolve with ongoing archaeological discoveries and interpretations.
