Here’s what this story reveals:

An unusual archaeological discovery in eastern France has uncovered a combination of circular enclosures unlike anything previously seen.
The site shows evidence of use across at least three separate historical periods.
Some of the structures appear connected to burial practices, and researchers hope continued study will clarify the site’s age, development, and purpose.

Archaeologists working in Marliens, near Dijon, have uncovered not just one ancient circular enclosure but three interconnected ones creating an unexpectedly complex layout.

The French National Institute for Preventive Archaeological Research (Inrap) described the find as “unprecedented,” noting that the site contains layers of human activity stretching from the Neolithic era all the way to the early Iron Age.
