The search for invisible and clandestine burial places of victims of wars and totalitarian crimes is a very difficult task. Research and exhumation teams use various methods to help locate burial places. According to the experience of our team, one of the best sources of information about burials are archival and contemporary aerial photographs. During World War II, aerial photography became one of the most important tools for warfare reconnaissance. For this reason, huge numbers of aerial photographs are currently available, in which the victim’s burial sites have been accidentally recorded. Aerial photographs are often helpful not in the direct identification of graves, but in the reconstruction of topographies of individual objects within a defined period of time, and thus, indirectly, in the location of graves. The aim of the study was to demonstrate the usefulness of historical aerial, satellite and drone photographs in the process of searching for the remains of victims of armed conflicts and totalitarian crimes. The paper presents the experience gained in the course of research projects carried out.

Poszukiwanie niewidocznych i tajnych miejsc pochówku ofiar wojen i zbrodni systemów totalitarnych jest bardzo trudnym zadaniem. Zespoły badawcze i ekshumacyjne stosują różne metody pomagające w lokalizacji miejsc pochówku. Według doświadczeń naszego zespołu jednym z najlepszych źródeł informacji o pochówkach są archiwalne i współczesne zdjęcia lotnicze. Fotografia lotnicza w czasie II wojny światowej stała się jednym z najważniejszych narzędzi służących rozpoznaniu działań wojennych. Z tego względu obecnie mamy ogromną liczbę zdjęć lotniczych, na których przypadkowo utrwalono miejsca pochówków ofiar. Zdjęcia lotnicze są często pomocne nie w bezpośredniej identyfikacji grobów, ale w rekonstrukcji topografii poszczególnych obiektów w określonym czasie, a dzięki temu pośrednio w lokalizacji grobów. Celem badania było zademonstrowanie przydatności historycznych zdjęć lotniczych, zdjęć satelitarnych lub wykonanych przez drony w procesie poszukiwania szczątków ofiar konfliktów zbrojnych i zbrodni systemów totalitarnych. Praca przedstawia doświadczenia zebrane w trakcie zrealizowanych projektów badawczych.

Aerial photographs are extremely valuable, often underestimated historical sources. Their use gives very positive results pertaining to research in the field of military history. Photographs documenting the events of World War II constitute primary sources of great importance in many areas of historical research in which archival sources have not survived. As documented by case studies, they validate the legitimacy of basing research methodology on photographic documents. Following a short historical outline on the development of aerial photography, the author analyzes some cases related to Warsaw’s destruction and reconstruction of its urban layout, as well as the murders committed by the NKVD in Kharkiv and Mednoye.

The first aerial survey conducted within the vicinity of the ancient city of Metsamor and its cemetery detected several promising anomalies in the aerial photos and processed images within and beyond the known limits of the burial ground. The survey results are discussed in this article along with a brief outline of the burial types found in this cemetery.

The paper New Data for Research on the Cuiavian Strongholds from Mietlica and Borkowo concerns issues of archaeology and the protection of monuments. It briefly discusses the state of hitherto research and knowledge on the strongholds in Mietlica and Borkowo. Then there follows a thorough analysis of aerial photographs (made by Łukasz Oliwkowski) of both these defensive premises. e discussion is separately completed with data acquired in consequence of subsequent surveys of the strongholds in Mietlica and Borkowo, carried out in the years 2007–2014. In the case of the castrum in Mietlica, the aerial photos and field surveys allowed for the recording of traces of the area in front of the rampart, the moat and the gate. Furthermore, a putative course of the eastern rampart (now levelled) of this premise was identified. In the case of the stronghold in Borkowo, it was possible not only to record its shape (the premise is two thirds destroyed) but also to propose a daring supposition concerning the vicinity of this Early Medieval stronghold. Based on aerial photographs, it was possible to state that the stronghold was accompanied with a suburbium to the south-east. All these pieces of information seem to be relevant from the point of view of possible excavations at both sites in future. At the same time, this data should also be of significance from the point of view of the heritage protection service and the protection of the discussed strongholds.

The objective of the first step of the non-invasive survey carried out on the Mustis site described herein was to verify the possibility of locating archaeological remains and to detect the location of the supposed remains by geophysical measurements (magnetic and electric methods). Magnetic measurements were made with Geometrics G-858 Cesium magnetometer with two probes located on the same horizontal level at 0.5 m distance or on the same vertical level at 0.5 m and 0.75 m above the ground level. The instrument recorded the values of the total vector of the magnetic field strength and made it possible to calculate the pseudo-gradient of its components (horizontal or vertical). Electric measurements were made by means of axial dipole-dipole electrode configurations (parallel) with AB current electrodes with spacing of one metre and electrodes of potential MN (identical spacing) at equal distance D at 4 and 6 metres, which made it possible to record values of apparent resistivity of the subsoil, with the penetration depth of the current of c. 2.0 and 3.5 m, respectively, below the current ground level. At the time of the data interpretation, the suspected locations of the remains causing the anomalies were indicated by means of dashes of different colours and thicknesses (depending on the assumed depth of the structures). These indications, transferred on maps, can serve as a starting point for extensive analyses of the entire site and its surrounding area. The first non-invasive surveys carried out in Mustis have demonstrated the usefulness of magnetic and electric methods in mapping the preserved remains both inside and around the city. The obtained results enabled elaborating a strategy for the work to come. It is quite probable that the magnetic method will prove capable of indicating places where vestiges of constructions are preserved, while the electric method will determine the depth and conditions of deposition of localised structures.

A Forgotten Town, the Village and Manor Zwanowo. Contribution to the Studies into Late Mediaeval and Modern Settlement Complex in Niedźwiedziny (Hamlet Dzwonowo), Administrative District Wągrowiec, Great Poland. The article presents a preliminary interpretation of vegetation dissimilarities recognized due to the analysis of an orthophotomap published on the Internet site www.geoportal.gov.pl. The dissimilarities in question, visible in the grounds of the village of Niedźwiedziny (hamlet Dzwonowo), administrative district Wągrowiec, Great Poland (Wielkopolska), have been construed as the remains of a unique mediaeval settlement complex: oval-shaped village, chartered town and a mediaeval (?) and modern manor. During visits to the abovementioned sites, the area of the old churchyard cemetery was traced. On the basis of the written sources, it has been established that Dzwonowo was the main centre of the joint properties owned by Dobrogost – Poznań voivode, and subsequently his descendants.
