Stone Circles and Scottish Spiritualism: The Altar Stone, Celtic Mysteries, and Marc Stuart Medium

Stonehenge has long been one of the most mysterious and iconic sacred sites in the world. But new discoveries about its central Altar Stone are raising profound questions—not only about ancient Britain, but about the origins of Scottish Spiritualism, Celtic Spiritualism, and the teachings passed down today through Marc Stuart Medium Training. Could this ancient structure, far from being solely an English mystery, actually point north—to Scotland—as the spiritual centre of prehistoric Europe?

Why is Scotland such a powerful centre for Spiritualism today? Many believe it's because Celtic Spiritualism was never extinguished here. While the Romans conquered and culturally dismantled Celtic societies across nearly all of continental Europe, and imposed their own religion and structure across England and Wales, they never succeeded in conquering the Scottish Highlands.
This makes Scotland the only place in Europe where Celtic spiritual traditions were not systematically erased by Roman occupation.
That matters. Because while in other regions Celtic identity was fragmented or absorbed into imperial systems, in Scotland, it was preserved, reshaped, and passed on—not in texts, but in land, ritual, oral memory, and direct spiritual experience.

It’s this uninterrupted lineage that forms the foundation of Marc Stuart Medium’s theory of Scottish Spiritualism: that the unique, evidential, and controlled style of mediumship practiced in Scotland today is not just a modern technique—it’s the last living thread of European Celtic spiritual culture, handed down, adapted, but never destroyed.
Today, through Marc Stuart Medium Training, that tradition is being consciously revived and taught—bringing back a style of mediumship rooted not in vague energy, but in land-based spiritual memory and generational connection.
But what if Scotland’s sacred role in spiritual culture goes back even further—not just to the Celts, but to a forgotten civilisation thousands of years older?
Recent discoveries about the Altar Stone at Stonehenge suggest that northeast Scotland may once have been the spiritual powerhouse of all Britain—and possibly of Neolithic Europe—a revelation that unites history, myth, and mediumship in a way that feels less like coincidence, and more like a call from the past.
A spiritual legacy that predates the Celts entirely.
From Pre-Celtic Builders to Modern Spiritualists
The culture that built Stonehenge—including the Altar Stone—emerged in the Neolithic period, around 2500 BCE. These people:
Lived in stone-built settlements
Practised earth-based spirituality
Constructed massive monuments across Britain and the islands of Scotland
Had no metal tools, no written language, and no known gods—but they left behind circles that still radiate energy
The Celtic peoples, by contrast, arrived more than 1,500 years later, during the Iron Age (around 800–500 BCE). They brought with them metal weapons, horses, and oral bardic traditions—but not the stone circles. By then, Stonehenge was already ancient, and its purpose long forgotten.
That’s the break. The Celts did not build these monuments—they inherited them. They may have reinterpreted their purpose, performed new rituals at their sites, or absorbed them into their mythology. But the original spiritual system—whatever it was—had already passed.
This is what Marc means when he says:
“Scottish Spiritualism isn’t Celtic—it’s older than that. The Celts kept the memory alive. But the work began long before.”
Celtic Spiritualism, Stone Circles, and a Modern Medium’s Theory
For fans of Outlander, the idea that ancient Scottish stone circles hold magical power isn’t new. In Diana Gabaldon's bestselling series, stone circles act as portals across time, blending Celtic ritual, ancestral energy, and deep spiritual resonance. Marc Stuart, who met Gabaldon at the Edinburgh Book Festival in 2022, often reflects on how fiction can sometimes reveal truths that science only confirms later.
“If we could really step back through a stone circle, I’d go straight to meet the people who built the first ones. But sometimes I think… they’re still with us. In the work we do. In the land. In the timing.”
Marc’s model of Scottish Spiritualism is defined by clear evidence, rapid delivery, and a deep respect for spirit world boundaries. Unlike many North American “calling out” styles, Scottish Mediumship is built on control, spiritual etiquette, and connection to sacred land, all of which Marc teaches through Marc Stuart Medium Training.
And none of that prepared him for what happened next.
A Childhood Vision on the Altar Stone
Devi, now the CEO of Marc Stuart Medium, had a spiritual experience as a child that neither she nor Marc understood until very recently.
At just 7 years old, she visited Stonehenge with her family. While climbing across the stones—allowed at the time—she sat directly on the Altar Stone and had a powerful spiritual vision: people in robes dancing in a circle around her. It was clear, vivid, and strangely emotional. She never forgot it.

Years later, disillusioned with the calling-out style of American mediumship and suffering from years of uncontrolled spiritual contact and sleeplessness, she applied for what she thought was an ordinary admin role. She had no idea the job was for a spiritual business or that Marc Stuart was a medium.
When they met, Devi described years of poor sleep and psychic overwhelm. Marc instantly recognised what was happening and invited her into the Marc Stuart Medium Training programme.
After just one training session, she learned how to close properly—a cornerstone of Scottish Spiritualism—and experienced her first full night’s sleep in decades.
It was only after the 2024 discovery about the Scottish origin of the Altar Stone that the significance of her childhood vision truly struck home. The very stone she’d sat on—where she received that vision—was from northeast Scotland, the home of the tradition she had finally come to understand and embody.
Marc says:
“It’s probably coincidence. Or maybe just perfect synchronicity from our guides. Or maybe… Scotland’s still working at Stonehenge, in ways we’re only just beginning to see.”

Monument to Connection

Transporting a 6-ton stone more than 700 km (~435 miles) in 2500 BCE—before the wheel had reached Britain—required astonishing skill and coordination.
It likely travelled:
By raft, down the eastern Scottish coast
Around Britain’s southern edge
Up the River Avon to Salisbury Plain
This wasn’t a construction effort. It was ceremonial logistics on a national scale. And it suggests that northeast Scotland wasn’t peripheral to prehistoric life—it was a spiritual hub.
Marc teaches that modern Scottish Mediumship is about structure, evidence, and spiritual service. And the Altar Stone’s journey proves that such spiritual structure existed 4,500 years ago.
Beyond Boats: Was It More Than Engineering?
Why transport one massive stone from so far away?
Some believe the Altar Stone held ritual significance, its source regarded as sacred. It wasn’t a matter of construction—it was ceremony in action.
As Marc puts it:
“When people carry a six-ton stone across half a continent for ceremony, maybe we don’t need to know how. Maybe we just need to listen to why.”
Were These the Celts?
When the Celtic tribes eventually came to Scotland, they likely found sacred places already waiting. They may have layered their myths over older truths. But those older truths—the builders, the rituals, the guides—may still speak through Scottish Spiritualism today.
“It’s not Celtic revival,” Marc says. “It’s ancient continuity.”
Devi’s vision. Marc’s teaching. A Scottish stone at the heart of England’s most mysterious monument.
What started as one child’s strange experience has become a living spiritual lineage, now taught to others through Marc Stuart Medium Training.
Maybe it’s just coincidence. Or maybe, like the stone itself, some stories were always meant to be carried further than we imagined.
