These are standing stones and other remains of the first civilisations that built
permanent stone structures in the British Isles. They were built thousands of years
ago by people that were not significantly different from us. Our knowledge and technology
might have improved, but our instincts are identical.
Whatever they were built for, one thing is clear. Part of their purpose was to have
a visually dramatic effect on the landscape. This aspect of their performance is
every bit as valid today as it was when they were new.
If anything, their visual drama has increases as the world has now spent thousands
of years trying to erode them back into the landscape.
