The Enigmatic Tally Marks of Carn Enoch

High on the slopes of Dinas Mountain in Pembrokeshire, Wales, lies a place that few people ever visit, yet it holds one of the quietest and most haunting mysteries in the landscape. Carn Enoch sits high above the valleys, a lonely cluster of ancient stones where the past lingers in the wind. The rocks here seem to hum with memory. Each one has felt the passage of countless storms and the footsteps of people who lived and worked this land long before written history began.

Among these stones is one in particular that has stirred the imagination of archaeologists, historians, and travellers alike. On its weathered surface are a series of careful, deliberate cuts. They are not natural scratches. They were carved by human hands many centuries ago. The marks form a kind of tally, a rhythmic pattern of lines that might have once held meaning as clear to their maker as language itself. Today, they invite us to wonder what they were meant to record, or perhaps to remember.

The Landscape

Dinas Mountain stands in the heart of north Pembrokeshire, not far from Fishguard and the rugged coastline. It is a land shaped by ancient forces. The very bones of the mountain are made of Pre-Cambrian rocks, some of the oldest in Wales. Over time, these rocks were sculpted by ice, rain, and wind, giving rise to the fractured, stony outcrops that now form Carn Enoch.

The geology here tells a story of deep time. Layers of volcanic and metamorphic stone, known as the Fishguard Volcanics, make up the mountain’s core. These rocks are more than 450 million years old. Their surfaces are pitted, crumbled, and veined with minerals that sparkle faintly when the light catches them. It is easy to imagine why ancient people chose this site. The elevation offers wide views across the surrounding hills, the sea to the north, and the Preseli range to the east. It was a natural vantage point and a place that felt close to the sky.

The very name Carn Enoch hints at its ancient significance. “Carn” refers to a pile of stones or a cairn, often a burial or ritual marker, while “Enoch” may derive from old Welsh or biblical associations, giving it a sense of sanctity. Standing here, you feel a connection not only to prehistoric life but also to the elemental forces of nature.

The Discovery

The site has been known locally for generations. Farmers, shepherds, and wanderers on Dinas Mountain have long been aware of the strange scatter of stones near the summit. Yet it was only in the twentieth century that archaeologists began to document Carn Enoch more carefully.

Survey teams noted the remnants of hut circles and cairns, suggesting the presence of a small prehistoric settlement. From its position and structure, Carn Enoch likely dates to the Bronze Age, though there may be evidence of earlier Neolithic activity beneath the surface. The presence of cairns and the arrangement of stones on higher ground are typical of Bronze Age communities that used elevated locations for both living and ritual purposes.

What captured particular attention was the tally-marked rock near the heart of the site. It is a boulder with a series of vertical incisions cut across one face. The marks are surprisingly even, suggesting a skilled and intentional hand. Archaeologists began to wonder whether these grooves could represent more than simple tool sharpening or random scratching.

Carn Enoch is not large compared to other well-known prehistoric sites in Wales, but what it lacks in scale it makes up for in atmosphere and mystery. The archaeological record here includes traces of stone-walled enclosures, possible hut circles, and at least one ring cairn.

The cairn, slightly raised and made of smaller stones piled upon larger ones, may once have marked a burial or a boundary. The hut circles suggest that people lived here seasonally or permanently, tending to animals or perhaps serving a ceremonial function connected to the mountain. The settlement’s position would have made it ideal for watching over herds, tracking the movements of the stars, or conducting rituals aligned with the sky.

Excavations have been limited, but surface surveys indicate multiple phases of occupation. The stones have been rearranged over time, possibly reused by later groups who recognized the sacred or strategic value of the site. The presence of multiple cairns across Dinas Mountain suggests a network of related activity stretching across the ridge, linking Carn Enoch to other ancient sites nearby.

The Enigmatic Tally Marks

At the heart of Carn Enoch’s mystery lies the rock that bears the tally marks. To stand before it is to feel a strange connection with the person who once crouched there with a tool of flint or metal and began to carve. Each mark is deliberate. They are not scattered but organized, forming a sequence that appears thoughtful and intentional.

There are around twenty-eight to thirty-two lines, depending on how one counts them, which is intriguing because that number closely corresponds to the lunar month. This has led to one of the most enduring theories about the rock, that it was used as a lunar calendar.

If this interpretation is correct, the marks may have helped the ancient people of Carn Enoch track the cycles of the moon, marking the passage of time through its waxing and waning. The position of the markings relative to a natural groove in the stone may even indicate different lunar phases. Such an idea is not far-fetched. Many prehistoric societies measured time by observing the moon, and similar patterns have been found carved on stones across Europe.

However, there are other possibilities. The marks might have been a record of trade or livestock, perhaps counting animals, supplies, or days of travel. They might even have been a kind of personal ledger, a human attempt to make order out of the flow of daily life.

A simpler explanation is that the grooves were created while sharpening stone axes. The Bronze Age was a time of tool-making and craftsmanship, and sharpening grooves are found on rocks elsewhere in Wales. Yet the regularity and alignment of the marks at Carn Enoch suggest a symbolic rather than purely practical purpose.

The rock invites contemplation. Each groove feels like a heartbeat from another age. Whether it was a calendar, a ledger, or a ritual inscription, the marks are a rare and tangible connection between us and the vanished community that once called this mountain home.

Local Stories

Like many ancient sites in Wales, Carn Enoch has gathered folklore around it like mist. The mountain has long been regarded as a place of quiet power. Local people once spoke of pilgrims who passed along an old trackway that crossed the slopes, pausing to make their mark on the rock as a sign of safe passage. Some believed that to touch the stone brought luck for the journey ahead, while others thought the marks represented the number of travelers who had completed the crossing.

There are also whispers of older tales. Some say that lights have been seen flickering on the mountain at night, or that the wind carries faint voices on certain evenings when the moon is high.

These stories, though impossible to prove, reveal how deeply Carn Enoch has entered the local imagination. Even without clear evidence, the mountain exerts a quiet magnetism. It is easy to understand why earlier generations might have seen it as a liminal place, a threshold between the human world and something larger.

Connections to Other Ancient Sites

Carn Enoch does not stand alone. Across Pembrokeshire and the wider landscape of Wales, there are many sites connected by alignment, tradition, or mystery.

To the east rise the Preseli Hills, home to the famous Bluestones that were transported to Stonehenge. Archaeologists have long speculated that the people who built the cairns and circles in this region were part of a wider cultural network that stretched across Britain. It is tempting to imagine that the inhabitants of Carn Enoch were aware of, or even linked to, the builders of these great monuments.

Nearby lie Carn Ingli and Foel Drygarn, both ancient hillforts and ritual centers with panoramic views. The alignment of Carn Enoch with these sites suggests that it may have held a related function, perhaps as part of a sacred landscape oriented to natural and celestial features.

When viewed from Carn Enoch, the horizon is framed by ridges and distant peaks that might have served as seasonal markers. The rising or setting sun at solstice could have aligned with certain cairns or rock formations, providing a natural calendar. While direct evidence for astronomical alignment at Carn Enoch is limited, the possibility is strong. Across Britain, prehistoric builders showed a keen awareness of the heavens, and Dinas Mountain’s commanding views make it an ideal observation point.

The Enduring Mystery

The tally marks of Carn Enoch may never reveal their exact meaning. Yet their mystery is precisely what gives them power. They remind us that even the simplest of lines can hold worlds of intention. Each groove is an act of memory, of communication, of humanity.

The stones of Dinas Mountain are old beyond comprehension, yet someone once looked upon them and saw a surface that could hold meaning. That impulse to leave a trace, to record, to remember, is as old as humanity itself.

Carn Enoch stands as a quiet testament to that impulse. Whether the marks record the movement of the moon, the passing of days, or something entirely symbolic, they connect us to an ancient way of seeing the world. A way that measured life not by hours or machines, but by the turning of the heavens and the changing of the light.

Carn Enoch does not give up its secrets easily, but perhaps that is the point. It asks us not to solve, but to listen. It reminds us that there are still places where the ancient and the eternal meet, and where the stone itself holds the memory of those who once walked here, beneath the same sun and moon.
