As old as the hills
I was raised to believe Neolithic man regularly hefted boulders the size of buses halfway across the UK, because the five tonne “blue stones” of Stonehenge were mined from a quarry some 250km away. So I’m a little disappointed to find out that this week, scientists have pinpointed where the larger (25-30 tonnes) and more iconic sarsen stones came from. And it’s a wood only 25km away. Still, plenty of mysteries remain as to how and why such an engineering and logistics feat was accomplished. Read more here.
