Electric resistivity imaging survey was carried out at the archaeological site of Asea as part of a programme of cooperative research between the Swedish Institute at Athens and the University of Patras. This paper presents the geophysical results of the first field season 2001. It is intended to explore the buried extension of the city wall in order to contribute to progressive research on the responses of the resistivity method to intact subsurface archaeological features (wall, void, tunnel, etc.). The survey was performed by means of a Geopulse imager system with 25 electrodes and an electrode spacing of 1 m. The Wenner–Schlumberger array was selected for measurements. The city wall was imaged in both north and south directions. The results indicate that the resistivity method can provide a clear pseudo‐image of medium to large size walls with high accuracy on archaeological sites. Copyright © 2003 John Wiley & Sons, Ltd.
