New research is suggesting that Stone Age Britons were arranging hilltop monuments in an elaborate grid of isosceles triangles—allowing travellers to navigate the country without maps. Apparently, these markers included famous sites like Stonehenge and The Mount.
Basically, these stone markers were a like a primitive GPS—and the accuracy was quite astounding. Researcher Tom Brooks explains:
‘The sides of some of the triangles are over 100 miles across on each side and yet the distances are accurate to within 100 metres. You cannot do that by chance.
‘So advanced, sophisticated and accurate is the geometrical surveying now discovered, that we must review fundamentally the perception of our Stone Age forebears as primitive, or conclude that they received some form of external guidance.
