For over thirty years Robin Heath has researched evidence for a prehistoric science embedded within the surviving megalithic monuments in Britain, Ireland and France. A leading UK field researcher on Megalithic monuments, Robin is an independent researcher and a seasoned presenter. He has written and published nine books, co-authoring a further two, one with John Michell. Robin's books reveal verifiable evidence that a high cultural technology was built into the astronomical, geometrical and metrological qualities of many ancient monuments. But the subject of megalithic science is much more than this, for it also affirms the hermetic adage of 'As above, so below', and reveals a comprehensive prehistoric cosmology. With a background in engineering, Robin graduated with a BSc Hons in Electronics and Engineering Science from UCNW Bangor in 1970. He initially worked as a Research & Development engineer in semiconductor design, microliths, then technical marketing took him around many countries in the Far East. Eventually, after two children came along, Robin became a lecturer in Mathematics and Electronics, and in 1990 he left this profession as Head of Technology in a College of Further Education to explore the megaliths of Brittany for two years. Robin lives in coastal West Wales, where he and his wife Tricia keep an organic small-holding. www.robinheath.info

An astronomer turned archaeologist, Dr Fabio Silva's interests lie with how prehistoric societies have perceived their environment (skyscape and landscape) and used that to time and adjust social, productive and magico-religious behaviours. His research is global, but in this field he has largely focused on Portugal, the United Kingdom (including Stonehenge) and Malta. Fabio has been teaching archaeoastronomy / skyscape archaeology at university level for 15 years. During which time he also published dozens of research papers and edited volumes, as well as co-founding and co-editing the Journal of Skyscape Archaeology for the past decade. His “outstanding contributions” to the fields of cultural astronomy and archaeoastronomy have led to him receiving the Carlos Jaschek Award from the European Society for Astronomy in Culture in 2016. He is a Visiting Research Fellow at Bournemouth University, teaches archaeoastronomy at The Skyscape Academy, and runs Stone x Sky – a consultancy focused on skyscape archaeology research, education and outreach. https://skyscape.academy/

he revelation that Stonehenge's Altar Stone came originally from northeastern Scotland prompts the question of why drag a huge stone slab 500 miles to Salisbury Plain in southern England. Andrew Collins relates the history and current status regarding the Altar Stone and goes in search of its lost companion, Altar Stone 2, known to have been removed from the site in the 1600s. Working with Stonehenge expert Simon Banton, Andrew explains where these two stones might have stood, what their function appears to have been, and how the suspected distance between them reveals not only a unit of measure derived from Professor Alexander Thom's megalithic yard, but also the presence of Euler's Number, a mathematical formula thought to be behind the relationship between everything from the smallest particles in the quantum world to the largest of galaxies. Andrew shows also how Stonehenge functioned also as a microcosmic representation of the universe as well as a sonic temple that was able to generate very low souns at a frequency today associated with the creation of atomic matter at the time of the Big Bang.

Andrew Collins is a prolific author and the co-discoverer, along with Egyptological researcher Nigel Skinner Simpson, of a huge cave complex located within the shadow of the Great Pyramid. He co-founded the Origins Conference and hosts Megalithomania tours. www.andrewcollins.com

Hugh will explore the Olmec world of Mexico, a remarkable culture who are heavily overlooked. Hugh has been travelling there since 2010, and recently, with JJ Ainsworth, spent one month exploring the Gulf Coast of Mexico (last February). He had the chance to visit the rarely-seen Olmec quarry on private land with archaeologist Prof. Alfredo Delgado of Xalapa Museum. He also witnessed a stunning new discovery from La Venta, and may have discovered, with Alfredo, another Olmec site near the well-known site of Laguna de los Cerros and met up with Marco Vigato and got to see some sophisticated stonework far west of Mexico City which look like they were carved at Tiwanaku!

Hugh is an explorer, megalithomaniac and author of several books including Göbekli Tepe and Karahan Tepe: The World’s First Megaliths.

A 1990s Psychic Questing Adventure After gathering the legendary 7 Swords of Meonia, Andrew Collins psychic questing group carried out a series of ceremonies over 7 years at White Leaved Oak, the centre of John Michell’s Circle of Perpetual Choirs. The 1998 finale linked in with Collins Giza plateau work and saw a visionary extravaganza featuring people placed around the Choirs landscape listening to the 3 tonal notes of the Elder Culture as Andy led us at WLO down into the Giza Crystal Chambers. This is a snapshot of a pre-2012, pre-millennial time from which much has moved on but provides a hopefully inspirational example of how far one can go from an Earth Mysteries starting point.

This presentation explores how the Long Man of Wilmington, the iconic Sussex hill figure, can be understood as a monumental celestial timekeeper set within a carefully oriented ancient landscape. Through archaeoastronomical analysis, the Long Man reveals key turning points in the solar and lunar year, marking auspicious seasonal thresholds including solstices and major lunar cycles. When viewed within its wider landscape context, the figure emerges not as an isolated geoglyph, but as part of a sophisticated cosmological design. Reconsidered in this light, the Long Man may stand as Britain’s eastern counterpart to Stonehenge, a monumental expression of sacred time encoded into the land itself.

Stuart Mason is a researcher, folklorist, author, and ancient landscape guide with over 30 years of experience studying archaeoastronomy and ancient cosmologies worldwide. His work focuses on lunar cycles, solstices, and long-term celestial patterns, and lived ion remote islands in the Pacific, where he learnt the indigenous systems of navigational astronomy. His focus now is on exploring how prehistoric monuments encode astronomical knowledge within mythic and ritual landscapes. Through field research, writing, and guided exploration, Stuart investigates the enduring relationship between land, sky, and sacred time. He spoke at Megalithomania in 2007,  founded The Antiquarian Society in the same year, organised the Out of the Ordinary Festival in Sussex for many summers and his new book on the Long Man of Wilmington is being launched at Megalithomania 2026

In this immersive talk, Juliette Bryant explores the profound relationship between medicinal mushrooms, the living Earth, and our ancient sacred sites. From the mycelial networks beneath our feet to the stone circles and megalithic landscapes that map the energetic body of the land, we are invited to remember our place within nature’s intelligence. Blending nutritional science, plant and fungal wisdom, and deep earth spirituality, Juliette shares how mushrooms can support physical vitality, expanded consciousness, and give a renewed connection to the ancestral ways. This is a journey of remembrance — of food as medicine, land as teacher, and the human body as part of the great ecological web.

Juliette Bryant is a nutritionist and superfood expert, and is the founder of the School of Earth Wisdom. She is the author of Divine Detox, Divine Desserts, Superfoods and How To Use Them and 7 Magical Mushrooms, and has spent over 20 years exploring the healing power of plants, mushrooms, and natural nutrition. Juliette runs retreats, trainings, and workshops internationally, guiding people to reconnect with nature, nourish their bodies, and awaken their innate vitality. Her work weaves together modern nutritional science with ancestral Earth-based practices to support deep transformation and holistic wellbeing. www.juliettebryant.com
