A fascinating story about ancient man-made monuments, some over 5,000 years old scattered all over Britain. http://englishhistoryauthors.blogspot.com/2015/10/pathways-for-sun-britains-neolithic.html
These constructions all appear to have one thing in common: they were built with great accuracy and align perfectly with either the winter or summer solstice. Of course many unanswered questions arise: Why were they built? Did they aid the people living at the time to understand the universe? Agriculture? Seasons? Were they religious sites? How could people living so long ago have the means and intellect to build such complex structures?
Some structures are estimated to have taken 300 men 3 years to build. That’s a lot of manpower and effort to build a mound with a tunnel through it!
