Abstract Hittite civilisation is an historical imperial in Sivas-Kusakli during B.C. 2000 to B.C. 8000. Many geophysicians and archaeologist are still working upon the ruins of this empire. In this paper, our aim is to bring to light the archaeological structure of the North of Sivas-Kusakli using total magnetic anomalies. For this reason, wavelet and horizontal gradient-boundary analysis have been applied. The methods are also tested for synthetic examples and satisfactory results are obtained. We have extracted the historical walls which assumed to be used as towers. The circular structures closer to the considered walls are also being extracted in our studies.
