Attempted to visit this site last month - gates into relevant fields either side of it are now hung with prominent 'private' signs - asked guy on tractor who said farmer (his dad) has stopped allowing access to the tomb. Not difficult to trespass to it, of course, but ..... . Disappointing, but perhaps not surprising (from the farmer's point of view) considering the closeness to the beach, and crops being grown in the fields.
Something is not right. This message is just to keep things from messing up down the road
