The phrase, the past is a foreign country is completely true when you venture way back into English history. There are strange standing stones and circles that are still visible in the landscape, ancient earthworks, churches with pagan marks and wells that still have ritual significance even today. Even though modern archaeological techniques and science can go some way to explaining the sites, there is still so much we do not know or can even comprehend.
When this was published way back in 1974 they knew even less then, but there was plenty of speculation as to the origins of the stones, burials and henges. Some of the suggestions in here as to the original purpose of the place would not even be entertained now, for example there is way too much nonsense on UFO’s and Ley Lines. Hence it is now quite outdated, but I have had it sitting on a shelf for a decade and a half and though I had better read it. Extracting it from there reminded me a little of Time Team! What I did like though were the photos of the places, they harked back to a time before visitor centres and information boards and were often quite atmospheric.
