Please note that the black marks represent upright stones. Many of the stones that mainstream archaeologists think of currently as "fallen" were in fact intentionally placed horizontally, as at Arbor Low. See our previous posting at Stonehenge Deciphered. Such "flat" placed stones are marked grey in color.
Our placements of earthworks and stones in that drawing are not perfect (but we trust close enough to be useful). They are based on the fundamental Stonehenge groundplan drawing -- protected by Crown Copyright, and hence not used by us in the original here -- as prepared by the Ancient Monuments Branch, Ministry of Public Building and Works, England, as that drawing was reproduced on the inside front and back covers of Gerald S. Hawkins, Stonehenge Decoded, Doubleday, Garden City, New York.
In addition, we relied on a marvelously drawn map by Anthony Johnson at The Stones of Stonehenge to add more stones than those on the above cited map.
Our own drawing is new because we needed to prepare a somewhat simpler presentation -- if the above drawing can be called "simpler" -- in which the numbering was better readable and some of the main features more visible, e.g. our simpler presentation of the outer henge earthworks. Our placements are at best "approximate". This is not a professional survey.
We also did not try to mirror exactly the shapes of the stones from above, although the shape of some stones from above is in fact important (stones 38 and 14, and 9a and 9b, for example). Some stones we show from the side (e.g. 16, the reason will become clear in the next postings).
But first, let us take a look at an interpretative version of the above map, especially our view of the main axis and the so-called "station stones".
