This film coincides with the final archaeological exploration of the interior of the largest man-made mound in Europe - a journey to the heart of Silbury Hill.
But there is a much bigger story too, that of the people who built the Hill, subsistence farmers who’s beliefs drove them to sculpt the landscape of the Avebury area, leaving a legacy of great structures.
What was the world they lived in and why did they build Silbury Hill?
As the film unfolds over the course of this summer’s tunneling and excavations, major new discoveries help archaeologists understand this huge enigmatic monument
