Join me at the Megalithomania Online Conference on 8th – 9th May 2021. Discounted tickets available. Other speakers are listed on a previous post on this site, and include Mike Parker Pearson, Howard Crowhurst, Christine Rhome, John Martineau and Hugh Newman.  All at My lecture is scheduled for the Sunday, 9th May, start at 4:30pm and titled, Bluestone Magic: Revealing Waun Mawn

Brief Description 

To understand a megalithic landscape, one must focus on the liminal space between sky and landscape, where ‘the above’ meets ‘the below’ at locations where Neolithic folk chose to locate their major temples and other significant monuments. Unfortunately, the techniques required are not those preferred by present day archaeologists.

In his new richly illustrated presentation Robin Heath will share his latest research, which sheds new light on the function and purposes of the Waun Mawn site, in the Preseli region of West Wales, conferring a greater significance onto this monument than previously recognised.

Brief Biographics

Robin Heath is a seasoned researcher, author and presenter on prehistoric and ancient science, a subject that has become a lost legacy to the modern world but remains built into the design and construction of many megalithic monuments. Robin has written and published nine books, and co-authored a further two.

An engineering graduate, his background has enabled Robin to discover astonishingly elegant qualities in many Neolithic monuments, and reveal in their design an unexpected knowledge of astronomy, geometry and metrology. Robin’s goal is to see this subject incorporated within the history books of the future, a recovered legacy made plain for future generations, and recognised as the vital first chapter in any revised history of science.

Robin has lived for over 35 years in the Preseli National Park of coastal West Wales, 25 years with his wife Tricia.

2021 Megalithomania on-line conference details1

Coming shortly at a computer or iPAD near you. Here’s the poster for the conference, to whet appetites.

May 8th & 9th 2021.

Pembrokeshire people may enjoy finding out more about the Waun Mawn site. Loads of interesting topics to satisfy all megalithomaniacs!

The Original Bluestone Circle, yes or no?

Waun Mawn – is this the site of the Original Bluestone Circle?

a) How to find the site

The Waun Mawn sites are accessed from the B4229 Eglwyswrw to Haverfordwest road, along a gated farm track by the cattle grid at Tafarn y Bwlch ( Lat 51*58′; Long 4* 47′). During the recent Documentary The Lost Circle Revealed, shown on February 12th we saw evidence that supports the old folk legend that an original bluestone stone circle was once taken from the Preseli Hills of West Wales to Stonehenge. I would like to suggest some comments that may be useful in assessing this evidence and clearing up some unfortunate confusions that appear to have been made in the presentation of the material.

During the week following the documentary I  received and answered over 90 emails , and one of the main issues raised by these correspondences was a confusion as to just which of the involved stones formed the Waun Mawn referred to during the documentary. The OS map shows three separate areas where standing stones are marked. Below, I have included photographs of all three sites. The OS Map allocates this ‘title’ to the higher reaches of the prominent hill Cnwc y Hydd, yet there are extensive peat bogs down to the lower levels, and mawn means ‘peat’ in Welsh.

Locating the Three Groups of ‘Waun Mawn’ Standing Stones

a) The Two Leaning Stones

Walking along the pathway to Gernos fach farm from the small parking area next to the cattle grid at Tafarn y Bwlch, the first two stones are found to the left of the gated track, around 300m from the large gate. These are small, less than three feet high, and very much an aligned pair, each sloping at the same angle to the west and about six feet apart.

b) The Solitary Waun Mawn Stone

This is without doubt the largest stone on the moor and it stands, with considerable presence, some sixty yards from the right hand side of the trackway some 500 yards from the entrance farm-gate. The side by side photographs show the difference in size between this whopper and the much smaller standing stone within the claimed bluestone circle.


Th larger stone forms the southern point of a large geodetic structure,  a diamond shape aligned to the cardinal points of the compass (N-S-E-W). Revealed through surveying in 2009 it was found to suggest a vesica piscis construction, with Pentre Ifan on the East, the Neolithic burial chamber near the summit of Carningli (West) and the weird and spectacularly sited second ‘motte’ at Nevern Castle (North).  This largest upright stone is the Waun Mawn I refer to in my book Bluestone Magic, a Guide to the Prehistoric Monuments of West Wales (available from website online book-shop and elsewhere).

b) The Remains of a Stone Circle?

To get to the third set of stones requires that one takes a right just after passing through the gate, and follows the track up are around to the right for about 400m, taking a left turn and walking uphill to a fairly level plateau where there are four clearly identified stones that appear to have once been originally set along a curve. The first stone (going left to right) is recumbent, about eight feet long, the second is the sole upright stone, of pleasing symmetry and remaining fully upright. This stone is frequently referred to by earth mysteries folk, dowsers and ley hunters, cited as being a highly energetic stone that can cause ‘tingling’ when held or touched.  The third is another recumbent stone, and similar in size to stone one. The fourth stone is much smaller than the rest.

If you visit this claimed stone circle and the weather is good, I cannot recommend highly enough the value of walking on up to the summit of Cnwc y Hydd, where there are some very special perspectives on the Preselis and beyond to enjoy from the summit.

I hope this clears up the matter of which Waun Mawn stones are which. Slightly misquoting the late archaeologist Jacquetta Hawkes I now hope you will all ‘get the Waun Mawn stones you deserve!

Since the Lost Circle documentary, and as we are enjoying the first dry sunny days since over three months of fairly wet, windy and impossible surveying weather conditions, I decided it would be fun to check the measures, geometry and astronomy now being offered by Mike Parker Pearson’s team during that recent TV documentary, who were suggesting a diameter of 361 feet (110 metres), a circle almost identical with the size of the outer bank at Stonehenge. This does not wholly agree with my own measurements, taken too many years ago, but the Preselis is a big patch for just one person to get around.  In due course I will report back. Watch this landscape!


The Recent Passing of Dr Euan MacKie

The recent passing of Dr Euan MacKie, together with the earlier passing (in April) of Dr Aubrey Burl,  and that of professor Keith Critchlow, brings to an end those stalwarts who were part of the surge of interest, during the 1960s and 70s, in archaeoastronomy, earth mysteries and a general quest to connect to our ancestors, to better understand the ancient world so as to include the new data that was pouring in from the work of those three professors, Gerald Hawkins, Alexander Thom, Fred Hoyle and those such as John Michell, whose lot it was to become part of, if not found, an alternative way of exploring  our ancient and prehistoric past, often tabbed  ‘the lunatic fringe’  within archaeological circles.

Durrington Walls Pit Ring – Part Two

Part Two: Redefining the Stonehenge Landscape

Durrington Walls Pit Ring is by far the largest known example of a megalithic egg, when compared with other existing types of ‘egg’, such as Woodhenge (Type II, Thom, 1967), just south of Durrington;  Allen Water, near Hawick,(Type I, Thom, 1967 ); and Castell Mawr henge in Pembrokeshire (Type III, Heath, 1916), adjacent to the ‘bluestone’ outcrops of Preseli, in West Wales. Other surviving examples of ‘Type III’ eggs, which have semi-elliptical ‘blunt’ ends, include Hirnant cairn circle in Montgomeryshire (Type III Hoyle, 1977), and Glasserton Mains rock art, on the Machan peninsula, Dumfries and Galloway (Morris and Bailey, 1967).

In Part One, the map of the pits around Durrington Walls was shown to clearly define the known geometry of a circular ended Type II egg, based on the locations of the many pits that make up the ‘pit ring’ discovery at Durrington. This geometry was compared with that of Castell Mawr.

Part Two shifts the focus to a metrological analysis of the shape of this pit ring, exploring its apparent properties and the relationship between Stonehenge and Durrington Walls pit ring ,  whose centre is located at a distance of just under 2 miles to the north-east of Stonehenge.

A New Circle around Stonehenge.

Stonehenge displays some similar qualities to the pit ring in that both monuments have identifiable centres and both have connections with megalithic constructions beyond their enclosing ‘walls’or ditch and bank, which extend out into the wider landscape. My earlier posts on Woodhenge provide a good example of such an extension to Stonehenge. Both monuments are also redolent with geometrical and metrological information, the kind of evidence that I routinely work with.

The investigation here identifies and quantifies these similarities, and  concludes by identifying a possible further large circle, concentric to, but set well beyond the present boundaries of Stonehenge’s bluestone, sarsen and Aubrey circles, and analysis will suggest a highly significant underlying purpose for such a circle’s existence.

Exploring Durrington Walls Pit Ring

Part One:  Joining up the Dots

For pandemic reasons, the 2020 summer solstice sunrise gathering at Stonehenge was cancelled . The awesome sight of the rising sun over the Heel stone in line with the monument’s axis and the ‘avenue’ was replaced by an important discovery: A  huge ring of very deep and very wide pits had been discovered in the chalky subsoil around Durrington Walls, just two miles northeast of Stonehenge and a little north of Woodhenge.

The discovery of these pits is of great significance, and came in the form of a report of an on-going investigation report, the result of years of work by large team of archaeologists from many universities, and other specialists.

Due to the site’s proximity to Stonehenge – which is just under three miles to the southwest of Durrington Walls, the PR guys clearly thought it a good time to announce the launch at the summer solstice. The Guardian clearly thought so, coming on strong with this catchy title,

Vast neolithic circle of deep shafts found near Stonehenge : prehistoric structure spanning 1.2 miles in diameter is masterpiece of engineering, say archaeologists.”

Avebury: Review of the recent OS-style map

The new ‘White Edition’ map of Avebury (, 2019) should capture both hearts and minds, suggests Robin Heath.

Designer and collator Thomas Melrose has done what has been needed for many years – produced a superb graphical map of Avebury where all the stones are listed, all the recent archaeological evidence derived from LIDAR and aerial photography is included and, where applicable, shown on the plan. For the tourist or visitor it now becomes the must-have source material to have tucked away in a rucksack or large pocket during a walk around the Avebury Henge site.

But this new presentational format goes far further than this necessary accessory. Its accuracy is without doubt the best yet available to researchers, be they academic archaeologists or enthusiastic amateurs.

Finding Atlantis

A fully illustrated presentation beginning at 3pm GMT on Sunday, October 27 2019, at Small World Theatre, Cardigan. Robin Heath will be discussing his latest research which answers some of the trickier questions that get asked about the abilities of early prehistoric cultures. Includes Q&A session. Poster gives main details, here’s some more to whet your appetite…

Into Earth Mysteries? Ancient Landscapes? Alignments? Ley-Lines? (what are they, then?) megalithic and other prehistoric and ancient monuments? Atlantis – where was (is) it to be found and what was Plato’s myth all about?
Here’s an afternoon of time travel…going back in time and looking seriously at human origins as the clocks also go back in time . Booking recommended.

Megalithic Preseli Tour in mid September – places remain available!
