We present the results of geophysical survey of the burial mound necropolis Gnezdilovo-12, which has been completely destroyed by ploughing. The results of geophysical data interpretation are compared with the results of archaeological excavations, XIX c. maps and surface artefacts distribution, showing good correlation between the datasets. For the European part of Russia the investigation of Gnezdilovo-12 is one of the first examples of full-scaled geophysical survey of the destroyed burial site, which enabled the confident interpretation of the site structure and 3D reconstruction of the burial mound landscape.
