Abstract The workspace as Bouleuterion (parliament house) is located in the ancient city of Alabanda far approximately 7 km from Aydin, Çine. The works on the city plan are still continued by the Department of Archeology in Adnan Menderes University. In this work, a geophysical study based on electrical resistivity tomography (ERT) approach is used to bring out the existence of the buried structures and situations of ruins in Bouleuterion. This study is a good example of implementation of the electrical resistivity method to the archeology in a specific area (Bouleuterion). Furthermore, the paper shows to researchers practically advantages and disadvantages of Wenner and dipoledipole arrays that widely used in archeological prospection. Also with this work, a Bouleuterion has been subject of a geophysical article for the first time. By archeology and geophysics evaluations, it is proved that these ruins such as the cavea, stage, orchestra, and entrances are parts of the Bouleuterion. Keywords Resistivity . Alabanda .

and easy to apply geophysical techniques that give fast results have more improved this meaning. In here, it cannot ignore that geophysical methods are non-destructive for the ancient structure. Bearing these in mind, these days, geophysical techniques are frequently used in the investigation of archeological sites (Leucci and Negri 2006; Negri et al. 2008; Tsokas et al. 2009; Drahor et al. 2011; Papadopoulos et al. 2012). Buried archeological structures produce some anomalies (or effects) due to their different properties, and these features can be determined by geophysical methods. As shown in some of recent studies, using of these methods for modeling of underground structures allows to obtain more reliable results (Loperte 2011, Diamanti et al. 2013, Ekinci et al. 2014). The most common of these techniques in the archeogeophysics is the electrical resistivity method. With this method, ancient structures can be displayed before excavation by making measurements on earth. Electrical resistivity method is frequently used in studies that the image or map of underground in the archeological sites obtained via electrical resistivity tomography (ERT) (Drahor et al. 2008; Negri et al. 2008; Papadopoulos et al. 2012; Diamanti et al. 2013). The method is quite suitable for the determination of the w
