The word “megalith” simply means big stone and some of these stones are enormous.
Their purpose has now been obscured by the mists of time and it’s quite possible

They have all been significantly eroded to the extent that they no longer look anything
like they did when first erected. However, their position in the landscape has not
changed and that seems to be as important a feature as anything else.
