TheOldStraightTrack Investigated by Robert Symes
The last of six original inquiries into the truth behind famous mysteries and legends.
Unexplained standing stones, crumbling castles and churches: ancient remains all over Britain can be linked by leys, invisible straight lines running across the landscape. Some believers say leys are Old Straight Tracks - trade routes used by our prehistoric ancestors; others claim that they mark the flow of mysterious earth forces.
And archaeologists say they do not exist at all.
