In Brittany, France, thousands of massive standing stones stretch across the landscape like a frozen army. They form the Carnac Alignments—the largest megalithic site in the world, predating Stonehenge and the Pyramids. Who built them? Why were they arranged in such precise, geometric lines? And why did they stop?

In this episode of Unexplained History, host Tom McKenzie investigates the enigma of Carnac. We explore the ancient engineering required to move these multi-ton giants, the folklore that claims they are petrified Roman soldiers, and the modern scientific theories suggesting they were a sophisticated Neolithic observatory or a seismic detector. From the local legends of "Saint Cornely" to the controversial restorations that may have altered the site forever, we uncover the secrets of a landscape that refuses to be explained.
