I was wondering how did people perceive Stonehenge and other stone formations similar such as menhirs in Britanny etc throughout History ? Did they understand its purpose ?
There is more to be said, certainly about the second part of your question, but I answered an earlier post here some time ago asking about the ways in which Stonehenge was perceived over the centuries. You might like to review that response while you wait for fresh ones:
What did other periods in the history of the British isles think of stone henge?
