Nowe dane do badań nad kujawskimi grodziskami z Mietlicy i Borkowa

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.
