Ley lines are hypothetical alignments of ancient sites, natural features, and man-made structures, believed by some to hold spiritual or mystical significance. These lines are often drawn between landmarks such as stone circles, standing stones, and sacred sites, suggesting a connection between them. Proponents of ley lines argue that they represent energy pathways or channels that can influence the environment and human consciousness. However, there is no scientific evidence supporting the existence of ley lines, and many consider them a product of coincidence or imagination rather than a tangible phenomenon.
