The Amphiareion of Oropos, a sanctuary dedicated in the late 5th century BCE to the hero Amphiaraos, among the ancient monuments, a theatre not whole been revealed by excavation is to be detected by geophysical investigation. Electromagnetic (EM) measurements with conductivity meter in a certain field design but most important by a suggested processing and interpretation have outlined the area of theatre seats that have been covered by loose sediments. In addition other probable features been detected by EM indicate the position of subsequent ERT profiles. The later show in detail all features of the underground proving what EM has indicated along with other very useful information for the archaeologists in order to design their further research.
