Ancient Sites of Worship
Avalon has a rich history woven through many timelines... and the Truth to many of these ancient "Christian" sites has been forgotten.. waiting to be remembered...
​
We will be exploring the Lost Gnostic past of Avalon by exploring her Ancient Cathedrals, Churches and Chapels. Sharing forgotten histories & stories of the Real Jesus, Mary Magdalene and other key figures of the Essenes.... and how these sites became entwined with Celtic and Druid Mystical Lore long before the emergence of Modern Christianity.

The landscape of Glastonbury is just as important as her History. Woven into the magic of this land are a series of Ancient Hills which are home to many legends & stories. And we will be making a pilgrimage to these Sacred Hills....
