Last year, on this bleak and beautiful stretch of Norfolk coastline, a local man made an extraordinary discovery. Walking the beach at low tide he found a bronze axe head. Nearby, was a mysterious circle of eroded timber posts half buried in the sand, and in the middle of the circle was a huge upturned tree stump.It’s utterly intriguing nothing quite like it’s ever been found before and everyone wants to know who built it, what it was for and what it originally looked like.
