Archaeologists in Poland have uncovered remnants of the medieval city of Stolzenberg in the vicinity of the Zagrody settlement near Sławoborze, in the West Pomeranian Voivodeship. This discovery is significant as the first written records of Stolzenberg date back to the sixteenth century, while the foundation seeking this lost city relied on German literature from the nineteenth century to guide their research.

Initial evidence suggesting they were on the right track emerged from studies conducted in 2020 and 2021, where the exploration group "Parsęta" from Kołobrzeg aided archaeologists in finding over 400 metal artifacts. These items, which included tools, clothing elements, and coins, were dated to the period between the late thirteenth century and the fifteenth century, indicating the significance of Stolzenberg in the medieval era.

In 2025, further investigations such as geophysical analyses, LiDAR scanning using drones, and geological drilling were employed, leading researchers to confirm the existence of traces from this forgotten medieval settlement. They assert that the area of around six hectares shows substantial evidence of Stolzenberg's past, reinforcing the historical importance and potential archaeological value of the site.
