Well now, there is a question ... it does get trodden on, and I have no doubt that it has had impact from the occasional (though rare) pate (not the de fois gras variety); I have more than a sneaking suspicion that this was not the intended purpose of the granite work.
Aha! Then you ve been playing tricks with the camera angle, perhaps leaning over an edge or stepping below it and taking a pic of a raised parapet. Let s plump - first of all - for the Terrace!
Not The Terrace (if I had given you any other more specific clue - then the granite would have been out of the bag, with no requirements drawn from the little grey cells); by the way, today I discovered one more plus sign on The Terrace; but with still no coordinating information.
