1. Avebury is the largest known stone circle anywhere, with a surrounding ditch and bank a mile in circumference
2. The centre of Avebury is placed 4/7ths of the distance between equator and pole, at latitude 360/7*
3. A very detailed and accurate seven station closed traverse survey was undertaken by Professor Alexander Thom in 1978.
4. Thom reported that the perimeter of the outer stone ring was 1302.5 Megalithic yards (MY) of 2.722 feet, which is 3545.4 feet or 520 Megalithic rods ( 1 MR = 2.5 MY).
5. The geometry of the ring is based on a circle 200MY in radius (544 feet/ 1.66m) with centre at point D, exactly 60 MY from C (see diagram above).
6. A 3-4-5 pythagorean triangle ABC of side lengths 30-40-50 MR (75, 100 and 125 MY) defined much of the geometry. From the corners of this triangle (the stones/markers have long gone) three of the various arcs that make up the outer ring were struck. Their radii and arc lengths are as follows:
From A, B and C, each radius 260 MY, define arc FG, from A, arc HG, from B, and arc ML, from C.
In addition, there were two longer arcs struck from outside of the ring, of length 750 MY, from points W and Z (not shown on diagram). The remaining part of the perimeter is based on the forming circle perimeter, whose diameter is 200 MY..
7. The two inner circles are each 125 MY in radius and are therefore as big as any other true circle known in Britain, and the same size as the massive Ring of Brogar in the Orkneys.
8. Avebury, unlike nearly all other stone rings, has CORNERS, which demarcate the arc lengths. Thom
showed that all the arc lengths are integral in Megalithic rods, and total 1302.5 MY (521 MR)
9. Avebury is a MESS. The ring was heavily vandalised in history, has a village built within and
without it, and a major road system has quartered it (see piccy below). Most of the stones were fallen
or missing in 1930. Only nine still stood. Despite this, Alexander Keiller and other archaeologists were able to locate the majority of the remaining stone holes in the chalk and restore much of the original monument, The geometry of the original ring has since been discovered by AlexanderThom.
10. When built, the outer stone ring contained either 98 or 99 stones, some weighing over 50 tons.

Below is a review of Temple in the Hills, given a five star rating by the reviewer. It’s better than any Easter egg. Half the print run has gone after five months and the book section lets you know how you may acquire a copy. An early chapter from this book is blogged earlier on this site.
I am currently working on a second site in southern Britain, and it appears that the ground rules given in Temple in the Hills concerning the relationship between Stonehenge and the (earlier) ritual landscape of the Preseli Hills (bluestones, remember?) are applicable elsewhere within the major megalithic sites of Britain and Brittany.
To slightly adapt the quote from Mike P-P, “There has never been a better time to be an archaeoastronomer.”
Three yonking great stones that mark to the Equinoctial (west – 270*)) sunset, part of a section of the Dinas Cross to Pontfaen road in the Preselis, near Russia (’tis true!), where the road markedly changes direction and follows the alignment for about 470ft (170m). Two of remaining three upright stones are those stand in front of the sun’s disc in the distance. All other stones are now recumbent, and lie buried in the bank, just as one finds at the minor standstill moonset ‘detector’ (301.4*) at Parc y Meirw (Field of the Dead) on the Llanychaer road, about a mile away. Prehistoric precision astronomy at its best in Preseli!
For nearly ten years I have had to wait in order to capture the sun’s disc located at the end of this alignment during its setting moments on the day of the spring equinox. For more details, avail yourself of a copy of Bluestone Magic, a Guide to the Prehistoric Monuments of West Wales – as these sheep clearly did – page 56 and elsewhere, which contains colour photos and explanatory text about these two robust alignment sites.
Thunderbirds are go! I have recently been invited to give a presentation on my work in the Preseli Hills at the first of the above events.
This first event is being held at the Memorial Hall in Newport, Pembs, which is located on the right as one leaves the village travelling on the A487 towards Fishguard. Please note that parking can be the devil’s own business there, so the Carpark down the hill may be a wise decision, travelling towards Fishguard, and before you get to the Memorial Hall, it’s on the left at the main crossroads in the town, and just a short walk gets you to the hall.
I am informed that fizzy stuff and canapes are going to be available, and I’m told by Paul Sanday, a geologist and the organiser of the event, also one of the speakers, that he wants to “get things moving on the debate about Stonehenge’s connections with the bluestone sites within the Preselis”. I wonder how much stirring of these dark and well muddied waters might he be looking for!? Usual photos, storyline and new research from me, plus question time and jolly books for sale with some humour. Could be a lot of fun.
The second event is hosted by the long standing, successfully managed and well informed West Wales Dowsers, associated with the BSD. The venue is Bronydd Village Hall, about two or three miles from Carmarthen on the main Newcastle Emlyn road to Cardigan. The post code is SA33 6BE for all you non-dowsers. And for those who eschew the sat-nav, one turns at the sign for the steam railway, following the road past the station, then, after about a quarter mile the village hall is on the left. The clue is that it looks just like a village hall, and is sited opposite Timberman and before the charming bridge over the river. Huge free carpark.
Doors open at 1:45 for a 2pm start. I’ll be presenting lots of stuff about my research, and my latest book, Temple in the Hills, plus a Q&A session, and you’ll also get the chance to mingle and chat with loads of nice folks into all manner of interesting aspects of the earth mystery genre. The secretary is Jennifer Forrest. Certainly better than watching an old black and white ‘B’ movie on the telly! All done by 4:30pm, in time to get home for Countryfile.
Here is a tarted up version of the first geodetic survey around Pentre Ifan and Carningli, in spring 2009. This first saw the light of cyberspace on the skyandlandscape (SL) website. The survey was undertaken with a Wild T16 theodolite, pegs, GPS device and tapes, and it revealed a complex isometric (equal lengths) megalithic structure across the eastern flank of Carningli mountain. The corner ‘points’ of two back-to back equilateral triangles were each marked with significant and large well known prehistoric monuments.
Read on! The PDF is free to go for students, megalithomaniacs, and even archaeologists (for non-commercial use only and the source must be credited). The whole story of this survey is told in a fully illustrated colour book Bluestone Magic – a Guide to the Megalithic Monuments of West Wales, available from this website (see books section for details as to how this book can be rapidly be found landing on your doormat).

The first review of my recent book, Temple of the Hills has been received from author and researcher Dr Thomas K Dietrich, whose most recent book, Temple of Heaven and Earth – Guide to Earth Energy & Inspiration at Sacred Sites was published by Save our Sacred Sites Society, San Bruno, California. It is a thorough and coherent account of the ancient roots of human encounters with what John Michell (in The View Over Atlantis) called ‘Spiritual Engineering’ and which has since come to be re-categorised as ‘earth energies’. A professional stone-image carver, once a student of the late Professor Rodney Smith during the 1960s, Dietrich has spent a lifetime reading ancient history, mythology and science, living in Ireland for thirteen years and travelling widely, investigating ancient sites throughout Europe, Corsica, Sardinia, Tenerife, Malta, Rhodes, Crete, Greece, Turkey, Egypt, the Red Sea, Israel, Jordan, in addition to the American Southwest, Mexico, Yucatan, Belize, Guatemala and South America, Ecuador, Bolivia and Peru.
An active researcher, Dr Dietrich has written The Earth Holder (1983), The Origin of Culture and Civilisation (2005), The Culture of Astronomy (2011) and Temple of Heaven and Earth (2016).
Dr Dietrich is therefore among the rather too few people who are amply experienced and qualified enough to be able to write a critical review of my own work, for which I warmly thank him.

Photograph Two. Castell Mawr Henge. Larger than Stonehenge Over 500 feet ‘diameter’, this site sits perched on the flat summit of a rounded hill near Eglwyswrw, north of the Main Preseli ridge and off to the left of the dolmen in the previous photograph (Image via the wonderful Google Earth).
I thoroughly enjoyed Temple in the Hills, and many others will enjoy it also. Your excellent surveys are really the key to convincing archaeologists of the broad scope of ancient science and knowledge. I have attached a short review and do firmly believe that we should encourage students to follow your footsteps in metrological surveys so that more people may convince themselves of these essential sciences.
Best Regards and Thank you again for your inspirational book!

Here is his review:
TEMPLE IN THE HILLS, The Discovery of the Original Stonehenge by Robin Heath
The introduction to Temple in the Hills by Robin Heath traces olden traditions and modern movements concerning the bluestone circle at Stonehenge, Zodiac hunters, New Age celebrities such as John Michell and Alexander Thom. The main corpus is dedicated to a review of astronomical phenomena and especially Heath’s discovery of the ‘Lunation Triangle’ within the context of ’the 30-segment, marked rope & peg’ configuration producing the 5-12-13 triangle which numerically defines the Moon’s relationship with Sun and Earth. Heath also gives a basic primer upon how to construct an accurate Equilateral Triangle on the landscape; again by simple rope & peg implements, showing that detailed, large-scale surveys may be achieved with very simple tools –proving that complex constructs were well within the abilities of our Stone-Age ancestors.
Robin Heath brings a solid case of evidence in favor of Neolithic metrology into the courtroom of archaeology. The evidence turns upon his measurements and discovery of ‘the Preseli Wheel’, centered upon the 500 foot diameter henge at Castell Mawr. Heath delineates five spokes of this wheel: Llech Drybedd, Carningli Summit, Foel Feddan, Carn Menyn, and Foel Drygarn which each average 18,630 feet (3.52 miles) upon the Preseli circle. The evidence of this wonderful precision is an indictment of modern archaeology’s continuing neglect to embrace and acknowledge metrological data and refined astronomical alignments. Heath returns to one of his 2010 investigations of his survey of the Preseli Vesica showing the distances between five locations upon a diamond pattern of two base-to-base equilateral triangles. The length of the common base and the sides of these two equilateral triangles show a nearly equal length and a mean distance of 11,759.0 feet demonstrating; in the author’s own words, “An accuracy that showed it to be a surveyed structure.”
Heath’s detailed demonstration of these irrefutable similar dimensions at the Preseli Wheel and Preseli Vesica represents no small contribution to science –because every well-documented opus elevates and substantiates the case for large-scale Neolithic metrology, precision alignments, as well as the broad based canons and traditions involving cycles, numbers, and geometry. It is absolutely important to celebrate this achievement for what it has and will accomplish. But, rather than bemoan the slow acceptance of new scientific data, I am quite sure that colleges and universities would take up such an interesting project for their students to gain valuable expertise in metrology; namely, to confirm Robin Heath’s survey measurements. This would once and for all guarantee the acceptance of accurate large-scale metrology in the Neolithic period and ignite a fire under the dragging feet and torsos of the archaeologists.
In his conclusion, Robin Heath presents the initial stages of his paramount discovery that the Aubrey Circle and the Sarsen Circle of Stonehenge bear the same relationship to one another as do the Preseli Wheel and its central circle around Pentre Ifan and Eglwyswrw. This correspondence shows that Stonehenge was based upon the template of the Preseli Wheel in Wales dated between 3200-3800 BC. Heath notices that genetic biologists conclude that the brain capacity of humankind has been more or less the same for almost 200,000 years. TKD
