The title and post are pretty lacking, here are some top level details to help you decide if you want to read more:

the forgotten Polish city of Stolzenberg

They brought in drones equipped with LiDAR and began drilling geological wells over six feet deep to search the northwestern Polish forests for remnants of the city.

Radiocarbon dating of the site set it back to the late 13th or early 14th century, but the city did not remain populated for terribly long. Stolzenberg was known to be abandoned by the 19th century, with the historical record calling it a “dead” town. Archaeologists believe the site was likely founded as a border town, possibly by members of nobility known as the Brandenburg margraves, military commanders charged with guarding the borders of the Holy Roman Empire. This conclusion is far from a certainty, however; others have speculated that the city could have been created by the bishops of Kamie, a Roman Catholic diocese in the Duchy of Pomerania from the 12th to 16th centuries
