Non‐destructive Electrical Resistivity Tomography Survey at the South Walls of the Acropolis of Athens

A non-destructive electrical resistivity tomography (ERT) survey at the Acropolis of Athens revealed areas of increased moisture behind its south walls, offering new insights into the structure's internal composition. Unlike traditional methods, this study used bentonite mud electrodes to avoid damaging the site, adapting existing ERT processing algorithms for this unique application. The findings not only assessed the wall's thickness in specific locations but also demonstrated the feasibility and utility of ERT surveys for archaeologists and restoration scientists, providing valuable data without compromising the integrity of the historic site.
