Grave goods buried with the dead, such as jewelry and weapons, could be relics of paganism that remained as Christianity rose in Poland.
The discovery began with construction breaking ground for a gas pipeline in the village of Borkowo in central Poland, where an ancient grave was found.
Archaeologists, led by Piotr Alagierski, excavated the site, revealing an entire cemetery dating back to the 10th century, with at least twenty people buried near a fortified settlement.
While human remains from this period have been found in Europe before, mass burials are rare.
