New geophysical surveys of a 6,800-year-old settlement in northern Serbia have pushed its estimated peak population from roughly 200 people to more than 700, more than tripling the earlier figure. The same fieldwork nearly doubled the site’s known footprint, from about 5 hectares to more than 9. Researchers say the revised numbers make the settlement, known as Opovo Ugar-Bajbuk, one of the larger Late Neolithic communities yet mapped in Serbia’s Vojvodina region.
The upward revision does not change the settlement’s age near 4,800 BC. It changes only how many people likely lived there at once, and how much ground their houses, pits and boundary ditches actually covered.
Magnetometry and core drilling replace the spade
Rather than opening new excavation trenches across the site, the research team relied on magnetometry to map buried house foundations and pits, systematic surface collection to catalog pottery scattered across plowed fields, and core drilling to sample deeper deposits without disturbing them. Fieldwork for the reassessment ran from 2022 through 2024, carried out by a joint German-Serbian team that walked the fields season after season rather than opening a single new excavation block. The approach let researchers survey ground that decades of conventional digging never reached, covering the settlement’s full extent instead of the isolated trenches that produced the original 1980s estimate.
That combination of non-invasive methods produced the higher numbers. According to a report on the findings by HeritageDaily, the survey put the settlement’s area at more than 9 hectares, up from a previous estimate of roughly 5, while mapping between 180 and 220 individual house foundations across the site. That structure count is what pushed the estimated peak population from about 200 residents to more than 700, more than tripling the figure archaeologists had relied on since the original excavation. Because the higher count comes from foundations visible in survey data rather than from artifacts pulled out of the ground, the researchers describe it as a maximum estimate rather than a fixed head count.
The reassessment was led by Kiel University, working with Serbia’s National Museum of Pančevo, the Museum of Vojvodina and the University of California, Berkeley. None of the four institutions dug a new excavation trench to reach the higher figures; the correction came entirely from remapping ground the 1980s dig had already passed over without fully surveying it. That earlier excavation, conducted before geomagnetic survey was routine in the region, sampled only a portion of what turned out to be a much larger settlement.
Radiocarbon dating places peak habitation near 4,800 BC
Radiocarbon dating placed the settlement’s principal occupation between roughly 4850 and 4725 BC, with the survey work distinguishing two separate phases of habitation at the site rather than one continuous, unchanging settlement. The two-phase breakdown suggests Opovo Ugar-Bajbuk was resettled, reorganized or expanded at least once during its history, though the surviving evidence does not say which, and the dating alone cannot tell researchers whether the population grew gradually or arrived in a single wave.
The settlement belongs to the Vinča culture, a Late Neolithic tradition already documented at dozens of sites across the central Balkans, from Serbia into Romania and Bulgaria. Few of those sites, however, have been resurveyed with this level of non-invasive detail, part of why a 6,800-year-old village could still triple in known size this deep into the region’s archaeological record, and part of why similar revisions could follow at other Vinča-culture sites still mapped only from decades-old excavation reports.
A low Gini index points to a cooperative society
The reanalysis also found little difference in house size across the settlement, producing a median Gini index of about 0.22, a statistic economists and archaeologists use to measure inequality on a scale from zero, representing perfect equality, to one, representing maximum concentration of wealth. A score that low points toward a community where most households lived in roughly comparable structures rather than a few large houses towering over many small ones, a pattern that cuts against the assumption that a settlement approaching 700 people would need a visible ruling class to organize it.
Multiple ditches enclosed parts of the settlement, up to five of them ringing sections of the site, and digging and maintaining that many earthworks would have required sustained group labor over time. The survey turned up no sign that the work was compelled, no fortified compound and no obviously larger residence, a pattern the researchers tie to cooperation rather than the elite-controlled model sometimes proposed for large Neolithic sites.
The full findings are published in Archaeologia Austriaca, where Fynn Wilkes and co-author Martin Furholt detail the survey methodology alongside the settlement’s two distinct occupation phases. The paper stops short of explaining what drove the shift between those phases, leaving open exactly why a community that grew to more than 700 people, spread across more than 9 hectares, changed shape over its lifetime without leaving behind the kind of hierarchy researchers often expect from a settlement its size.
