Discovering the Original Stonehenge in the Preselis

robin-at-dolmen-llech-y-drybeddPresentation Event at Castell Henllys on 19th October 2016, starting at 7:30pm

Prehistoric archaeologists are currently focussing their attention on the Preseli region of West Wales. Why are they here, and what are they looking for?

The answer has to do with Stonehenge, 140 miles away in Wiltshire. Some of this mighty monument was constructed using bluestones that originated here in the Preselis. A fiery debate is raging about how they got there, whether they were taken by human toil or arrived on Salisbury Plain through glacial action.

So archaeologists are now looking for evidence of an original bluestone circle here in the Preseli hills, looking for surviving stones which, if they geologically match those at Stonehenge, will prove that human intent moved them there.

Robin claims to have recently discovered the original design for Stonehenge here in the Preselis, and has surveyed it using a theodolite. He will show this design has more to do with the Caer Sidi of Welsh legend, and the motions of sun, moon and stars, than it has with how a few bluestones ever found their way to Salisbury Plain.

In his illustrated and not too technical presentation he will also reveal that Stonehenge was a derivative taken from an original design conceived here in Wales, so how good is that?!

A graduate of UCNW, Bangor, Robin Heath was previously a research and development engineer with Ferranti, then a college head of technology department, late of Coleg Ceredigion. Since 1990, local author and presenter Robin Heath has been finding the prehistoric science embedded within the surviving megalithic monuments in Britain, Ireland and France. In 1993 Robin founded Megalithic Tours and has written ten books revealing evidence of high culture to be found in the astronomy, geometry and metrology of ancient artifacts. This material has been presented to students at the Prince’s School of Traditional Arts, John Ruskin College, Brasenose College, Oxford, the British School of Dowsing, The Gatekeeper Trust, RILKO (Research into Lost Knowledge Organisation), and the Royal Institute of Mathematics.

 A launch copy of Robin’s latest book, The Temple in the Hills, will be available at £10.

Prehistoric Surveying of the Landscape: The Evidence


An Illustrated Presentation given at Castle Henllys centre
on the 18th November 2015 at 7:30pm
by Robin Heath

What  were  megalithic  monuments  for?  

Despite  centuries  of  inquiry  by  archaeologists  and prehistorians  the  key  question  remains  unanswered.  Why  were  so   many  massive  stone  structures  erected  across  the  ancient  and  sacred  landscapes  of  the   world,  including  the  Preseli  region?

One  answer  to  this  innocent  question  lies  in  the  fact  that some  stone  circles   employ  the  same  geometrical  techniques as  do  surveyors  and  navigators.  This  fully illustrated talk shows how geometrical atterns became imprinted on the  local  and wider  landscape  of  Britain,  revealing  a  remarkable  purpose for the  megaliths,  a  purpose  based  on  the  importance  of location  ­‐‑  the  right  place.

Just  how  did  they  determine  the  right  place?  

Come along and find out, and have your present model of history recalibrated, as  we  also  discover  that  the  later  Celtic  and  Roman  Church  reapplied  the  ‘ʹpagan’ʹ  techniques  of  the  megalith  builders  to  suit  the  requirements  of  the  new   Christian  era,  ultimately  using  them  to  locate  Gothic  cathedrals.


Castell Mawr, Eglwyswrw, PembrokeshireHenllysTalk-3

HenllysTalk-2 For over thirty years, Robin Heath has looked for evidence of the science underpinning the culture of the megalithic monument builders. Over this period Robin has written ten books on ancient astronomy and geometry, and most recently has been engaged in research looking for evidence of larger geometrical patterns across the landscape, based on the location and placement of networks of ancient monuments. Previously having worked with John Michell and local antiquarian, the late John Sharkey, Robin has presented some of this material on TV documentaries, to megalithic tour groups, and also to students at the Prince’s School of Traditional Arts, John Ruskin College, Brasenose College, Oxford, the British School of Dowsing and the Faculty of Astrological Studies. He lives in the Preseli National Park, in Pembrokeshire.

The Annual Robert Cowley Memorial Lecture – 24th April 2015

The Annual Robert Cowley Memorial Lecture

Robin Heath Friday 24th April 2015

[The RILKO AGM will be held from 6.45 to 7.15 (Doors open 6.30pm)]
The public is warmly welcomed to the lecture at 7.30pm

Entrance: £8.00    (R.I.L.K.O. Members £6.00)

This illustrated lecture will present robust evidence that the world was surveyed and measured in prehistoric times. The technological residues from this activity will be shown to be recognisable in modern  times, and are found permeating presently employed measures, astronomical, geometrical and geodetic techniques and within prehistoric monuments, where this evidence remains almost completely unrecognised within archaeology. Find out why!

Robin Heath has a science degree and was a research and development engineer before becoming the head of technology at Coleg Ceredigion. The author of eleven books, he lectures widely on the subject of megalithic science and the evidence for ancient wisdom and has worked on projects with the media, John Michell and Paul Broadhurst, and his brother and fellow author Richard Heath.

The Research Into Lost Knowledge Organisation Public Lectures are held at
50 Gloucester Place, London W1U 8EA.

Nearest Underground Station: Baker Street
Buses: 2, 13, 30, 74, 82, 113, 139, 189, 274 pass outside.
