Geophysical surveys were carried out around the ancient settlement of Poliochni on Lemnos Island in order to direct archaeological excavations towards places where remains could be discovered. Because direct information on the physical properties of the remains was not available an integrated geophysical prospection, including magnetometric (proton precession and fluxgate magnetometers), electromagnetics (very low frequency) and resistivity measurements, was undertaken. Line spacing and dimensions of the spreads were chosen presuming that the archaeological structures investigated were not located below 10 m in depth; also in the data processing, by using high pass filters, superficial signals are enhanced. The results indicate that the environment probably underwent modifications due to the presence of the local population. Test excavations carried out as a follow‐up to the magnetic survey uncovered a structure (road?) probably built during the Roman occupation of the island and a medieval tomb. Geoelectric and electromagnetic surveys yielded interesting results, which can be ascribed to geomorphological variations within the soil cover; they indicate that the local population attempted to reclaim the area for agricultural purposes.
