Avebury Code Past.jpg
AVEBURY: BREAKING THE MEGALITHIC CODE. Avebury is not only the largest stone circle in the British Isles, but it is also a huge complex comprising an astonishing assortment of nearly every kind of megalithic monument. The perfect place for the Earthquest event, where Graham Phillips and Debbie Cartwright revealed, for the first time, their latest astonishing discoveries about how the Druids preserved the secrets of the Megalithic Age.
When? Sunday 7th June 2026
Where? Avebury, England

The Neolithic people who built Avebury around the same time as Stonehenge, about 4500 years ago, left no writing to reveal their secrets. So, for millennia, its true purpose has remained a mystery. But Graham’s latest research suggests the Megalithic culture passed its secrets on to the Celtic people who succeeded them, as climate change brought it to an end. Although the pre-Roman Celts left no records, the Romans and Greeks they encountered, and later Christian writers did. From their painstaking study of these works, Graham and Debbie have unraveled the mysteries of Avebury and the Megalithic British Isles.

Mysterious Avebury

  • A megalithic monument large enough to hold the entire population of southern Britain at the time.

  • A gigantic ditch and embankment, almost a mile in circumference, with the ditch on the wrong side to be used for defence.

  • Two avenues of hundreds of parallel stone rows, each extending over a mile in a different direction, to end at further megalithic sites.

  • The Southern Circle, with its cove of giant stones weighing up to 40 tons.

  • The Northern Circle, containing a unique square monument buried for centuries, is unlike anything found before.

  • Silbury Hill, an artificial hill over 130 feet high, with no burials or stone chambers within.
