The archaeological discovery was hiding in plain sight for centuries, tucked away in a field near the village Łysomice in northern Poland. But with the aid of Google Earth scans, archaeologists were able to spot concentric outlines of where the ancient structures, or pans, once stood. The researchers now believe the buildings were raised by some of the first European communities to farm the land.
The discovery dates the neolithic structures to about 2,000 years before the Great Pyramid of Giza was built in Egypt.
Mateusz Sosnowski from the Institute of Archaeology at the University of Nicolas Copernicus praised the unexpected find.
