Archaeologists have made a remarkable discovery in a remote forest in Poland, uncovering traces of a deserted medieval city known as Stolzenberg. This lost settlement, estimated to have been founded in the late 13th or early 14th century, lies near the modern village of Sławoborze in northwestern Poland, and its abandonment remains shrouded in mystery.
Initial Findings and Advanced Research
In 2020, preliminary metal detector surveys at the site revealed over 400 metal artefacts, including belt fittings, coat clasps, and medieval coins, hinting at a once-thriving community. Building on this, recent drilling has exposed layers more than two metres deep, with a visible central market and a street leading to what was likely the city gate.
Piotr Wroniecki, an archaeologist from the Relicta Foundation, explained to the Polish Press Agency (PAP) that in an area of approximately six hectares, surrounded by a rampart and moat, researchers recorded over 1,500 anomalies. These unusual terrain features suggest the presence of hidden underground structures, such as ancient buildings, pointing to a well-organized urban layout.
Historical Context and Potential Founders
According to the archaeological team, the Margraves of Brandenburg (Neumark), a significant principality within the Holy Roman Empire, are the most probable founders of Stolzenberg. The Relicta Foundation is now focused on clarifying the exact founding date and the circumstances that led to the town's depopulation, aiming to piece together its historical narrative.
Marcin Krzepkowski, also from the Relicta Foundation, collected data across 25 hectares while investigating the vanished city. He noted to PAP that while the population size and reasons for abandonment are still unknown, multiple factors typically contribute to a town's decline. Natural causes like floods, the decline of trade routes, and wars are all potential explanations for why Stolzenberg was deserted.
Technological Methods and Funding
The discovery was made possible through a combination of geophysical research, geomorphological drilling, and aerial terrain scanning, as detailed by the Relicta Foundation. In a Facebook post from December, the foundation described conducting non-invasive studies in October and November on the territory of the vanished medieval city, which was initially discovered in 2019 in the forests of Nadleśnictwo Świdwin, part of the State Forests.
This extensive research project received funding from the Minister of Culture and National Heritage, sourced from the Culture Promotion Fund, highlighting the importance of preserving and understanding Poland's rich historical heritage.
