The site at Jawty Wielkie, located in the Iława Lakeland in northern Poland (Fig. 1), was discovered in May 2015. A search carried out with the use of metal detectors yielded 50 copper-alloy artefacts (including 25 brooches, 11 bracelets, five belt buckles, two strap-ends and a spur) and an iron razor (Figs. 4–9). The finds were transferred to the collection of the Museum of Warmia and Masuria in Olsztyn. Some of the artefacts bear traces of burning; on several objects, traces of intensely black earth and charcoal have been preserved. These traces, as well as the structure of the discovered artefact assemblage, indicate that the site was used as a cemetery. The vast majority of the artefacts date to the Roman Period and the early phase of the Migration Period. At that time, the area of the Iława Lakeland belonged to the so-called zone D of the Wielbark Culture settlement. The oldest confidently dated artefact is a fibula of type A.III.53 (Fig. 4:1), which is a marker of phase B1b. What is interesting is that, until now, no brooches of this type were known from the area in question. Zone D was thought to not have been settled until stage B2b, however, the aforementioned brooch as well as the recently published, similarly dated finds from Bajdy, Przezmark and Zawada (A. Cieśliński 2020) indicate that the penetration of the Iława Lakeland by the people of the Wielbark Culture began earlier, in stage B1. The youngest artefact in the assemblage is a beak-shaped strap-end (Fig. 6:32), indicating that the cemetery was (continuously?) used until the early phase of the Migration Period. While the iron razor has analogies in the material of the Oksywie Culture from the Late Pre-Roman Period, no sites of this culture are known from the vicinity of Jawty Wielkie. In the northern part of the site, there is a group of small hills with a fairly regular, round bases, which resemble barrow mounds in shape and size (Fig. 10). Although the characteristics of these “tumuli” indicate that they are most similar to the mounds known from Wielbark culture cemeteries, it cannot be ruled out that they were built earlier – in the later phases of the Bronze Age or in the Early Iron Age. It is only possible to reject their later, early medieval provenance. The issue can only be resolved via archaeological excavations.
