Over 100,000 megaliths once covered the French region of Bretagne to the point where it resembled a forest of stone. It is the world’s largest megalithic metropolis. And yet in central Portugal and the isles of Scotland there exists the same phenomenon. Why were these three locations chosen above all others by Neolithic architects? And why were stones as tall as sixty feet transported from afar?

My latest documentary examines these regions — along with England — and finds they all share common characteristics: the selective choice of stone, areas of gravity and electromagnetic anomalies, fault lines, experiences of altered states, legends of submerged lands, folklore of faeries, gods and giants, and a language fingerprint originating in Armenia — seemingly unconnected elements that converge to explain who masterminded this megalithic enterprise. And why.
