Do ley lines exist in the landscape? The alignment of ancient sites (1500+ years) in the landscape is said to be evidence of ley lines. In the UK and elsewhere in Europe, it is said that many Saxon churches and pre-Christian monuments or earthworks can be shown to lie in straight lines. It is suggested that pre-Roman peoples used a system of markers on the landscape to find their way across great distances, and that these may have been the basis for some of the Roman roads. Similar straight lines are said to exist in South America. In addition to the physical reality (or otherwise) of ley lines, there is the further idea that they carry some kind of "earth energy", linking sacred sites such as stone circles. I wonder whether anyone has done a scientific study of this.

Have a look at Simulating the Ley Hunter, Simon Broadbent

> Megalithic sites, especially isolated standing stones, are believed by some to have been deliberately set out in straight lines known as leys. An alternative hypothesis is that these points are uniformly and independently distributed.

Lots of cool math. The bottom line: Ley lines are statistically random.
