The first examples of archaeo-geophysical investigations in the territory of Turkey, are seen in the 1960s. Archaeo-geophysical studies, which came to an important place in archaeological site investigations and documentation of cultural heritage sites after the 1990s, have taken place in many legislations in the country today. Recently, the employment of non-destructive geophysical techniques in Turkey’s archaeological sites has been drastically increasing. This chapter presents the history of archaeo-geophysical studies, methodological developments, educational and commercial advances. Additionally, widespread commercial applications, how archaeological site types are handled, verification of the relationship between geophysics and excavation results, and good practice examples are also summarised. In addition to the soil variations encountered in archaeological sites, the interpretation of the results of the geophysical techniques used in the determination of the archaeological context, which is highly complex due to ancient earthquakes in archaeological sites in Turkey, is also discussed in this chapter. Although archaeo-geophysics is an essential part of the study of archaeological and cultural heritage sites in Turkey, soil prospecting is limited and there appears to be a lack of integration in comparing geophysical results with the soil prospecting results.
