The Devil’s Arse of Castleton: Echoes Beneath the Peak
Tonight's Episode
At the edge of Castleton lies a vast opening in the earth—one of the largest cave entrances in Britain, and a place once known by a name few would use today.
For centuries, Peak Cavern was called the “Devil’s Arse,” a reflection of the strange sounds that echoed from within and the belief that something stirred beneath the surface. Early travellers, including Daniel Defoe, recorded its scale and atmosphere, while local tradition linked the cave to something deeper, darker, and unknown.
In this episode of Hidden Derbyshire: Folklore & Legends, we explore the history, folklore, and lived experience of Peak Cavern—from its role in local industry to its place in a wider tradition of caves as thresholds to the underworld.
Blending documented accounts with atmospheric storytelling, this episode examines how natural spaces become shaped by fear, imagination, and interpretation—and why this cave, more than most, has never felt entirely silent.

[SPEAKER_00]: There are places where the landscape opens outward.
[SPEAKER_00]: Wide valleys open the skies and distant views.
[SPEAKER_00]: And then there are places where it does the opposite.
[SPEAKER_00]: Where it closes in, narrows, Paul threw down wood into darkness.
[SPEAKER_00]: Pete Cavan at the age of Castleton is one of those places
[SPEAKER_00]: from the outside it begins with something almost theatrical, a vast arch of rock, towering above the village, like the entrance to something that was never meant to be entered.
[SPEAKER_00]: And for centuries, people have stood before it and asked for the same question.
[SPEAKER_00]: What lies inside?
[SPEAKER_00]: but just as often, they've asked something else.
[SPEAKER_00]: What might come out?
[SPEAKER_00]: Peak cavern sits beneath the village of Castleton in the heart of the peak district.
[SPEAKER_00]: It is one of the largest cave entrances in Britain and natural arch carved into the limestone of thousands, perhaps millions of years, by water moving through the rock.
[SPEAKER_00]: Even today a stream runs out of its mouth, cold and constant, emerging from somewhere and seen.
[SPEAKER_00]: The cavern itself extends deep into the hillside.
[SPEAKER_00]: A system of chambers, tunnels and passages that stretch far beyond what is immediately visible.
[SPEAKER_00]: And while parts of its now are accessible, guided, lit, explained, there remains a sense even now that what we see is only a fraction of what exists.
[SPEAKER_00]: that the cave continues beyond us, into the darkness, into the silence, into something undenaceted.
[SPEAKER_00]: For much of its history, peak cavern was not known by that name.
[SPEAKER_00]: Locally, it was called something else, something more direct, more unsettling.
[SPEAKER_00]: The devil's
[SPEAKER_00]: The name appears in records dating back centuries, used openly in earlier accounts, mentioned in travel writing.
[SPEAKER_00]: It was even referenced by figures like Daniel Duffer, who described the cave drilling his travels in the early 18th century.
[SPEAKER_00]: While the name might seem crude, it reflects something deeper, a way of interpreting the cave not just as a place, but as part of the body, a living landscape.
[SPEAKER_00]: The earth imagines as something organic, something with openings, with depths, with unknown interiors, and in this case an opening that expels sound, water, air, and something that seemed to come from within.
[SPEAKER_00]: One of the most consistent features of Pete Cavern, noted across centuries, is sound.
[SPEAKER_00]: It's not constant, but unpredictable, a deep, resonant rumble.
[SPEAKER_00]: Sometimes compared to distant thunder, and sometimes described as something closer to a roar.
[SPEAKER_00]: Early visitors wrote about it, travellers noted it,
[SPEAKER_00]: and in a time before geological explanation, sound like that required interpretation.
[SPEAKER_00]: Because it didn't feel random, it felt intentional, as though something within the cave was moving, breathing, reacting.
[SPEAKER_00]: The stream that runs through the cavern contributes to this,
[SPEAKER_00]: air pressure shifting within tunnels, creating echoes that don't behave in familiar ways.
[SPEAKER_00]: But without that understanding, the explanation becomes something else, but the cave was not empty.
[SPEAKER_00]: Across Britain, there is a long standing tradition of associating unusual natural features with the devil.
[SPEAKER_00]: places that feel out of scale with their surroundings or difficult to explain.
[SPEAKER_00]: The devil in folklore is often less a figure of theology, a more a way of describing the unknown.
[SPEAKER_00]: A presence attached to places that feel dangerous and unpredictable or beyond human control.
[SPEAKER_00]: In Derbcher, this association appears in multiple locations.
[SPEAKER_00]: with peak cavern that becomes central, because a cave doesn't just exist, it announces itself through scale and through its darkness and through sound.
[SPEAKER_00]: And so, the idea forms, not necessarily that the devil lives there in a literal sense.
[SPEAKER_00]: But that this is a place connected to something beneath the surface of the world, something deep in the landscape we see.
[SPEAKER_00]: By the 17th and 18th centuries, P. Cavan had become a site of interest.
[SPEAKER_00]: It was visited by travelers that were described in writing.
[SPEAKER_00]: Documented as part of a growing curiosity about Britain's natural features.
[SPEAKER_00]: Reuters like Daniel Defoe noted both its scale and its atmosphere,
[SPEAKER_00]: But even as these accounts attempt to describe the cave in observational terms, they don't fully separate from its reputation.
[SPEAKER_00]: Because the name remains, the devil's arse.
[SPEAKER_00]: Use not just casually, but as an attempted part of its identity.
[SPEAKER_00]: Later accounts, particularly in the Victorian period, began to shift home, there were more scientific, there were more structured.
[SPEAKER_00]: The cave becomes something to be studied, measured and explained.
[SPEAKER_00]: But the older name lingers, even as it becomes less socially acceptable to say.
[SPEAKER_00]: And gradually, it is replaced, it's softened and re-branded, as peak cavern.
[SPEAKER_00]: A name that describes its location, but removes its implication.
[SPEAKER_00]: For a time, the entrance to Pete Cavan wasn't just a natural feature.
[SPEAKER_00]: It was inhabited, families lived within the cave mouth, using the vast overhang as shelter.
[SPEAKER_00]: They worked there making rope.
[SPEAKER_00]: This wasn't unusual in early centuries, cave entrances provided protection from the weather, a stable environment, but it adds another layer to the site's history, because the cave wasn't just feared, or mythologised, it was lived in, integrated into daily life, which creates a contrast between the cave as a place of folklore and the cave as a place of ordinary existence.
[SPEAKER_00]: Caves change how we experience space.
[SPEAKER_00]: They remove distance, they limit visibility, distort sound, and in doing so, they alter perception.
[SPEAKER_00]: Inside a cave scale becomes difficult to judge.
[SPEAKER_00]: Sound behaviours them predictably.
[SPEAKER_00]: Light is controlled, limited, and artificial.
[SPEAKER_00]: And in that environment the mind begins to fill gaps to imagine what cannot be seen.
[SPEAKER_00]: This is where folklore thrives, not in the visible, but in the uncertain, because when you cannot fully perceive a space, you begin to interpret it, and those interpretations become stories.
[SPEAKER_00]: There is a long-standing idea across cultures, but caves represent entrances to something deeper, not just physically, but simulically, and underworld a space beneath the surface where different rules apply.
[SPEAKER_00]: In British folklore, this isn't always formalised, but it appears in fragments, caves as entrances to hidden realms, underground spaces linked to spirits or presences, and places where the boundary between worlds feels thinner.
[SPEAKER_00]: Pete Cavern fits easily into this pattern.
[SPEAKER_00]: Not because of a single story, but because of its qualities, its death, its darkness, its sound, and the sense to continue beyond what we can reach.
[SPEAKER_00]: Today, Pete Cavan is a managed site.
[SPEAKER_00]: Visitors enter in groups, guided through sections of the cave, given explanations of its geology and its history, its formation.
[SPEAKER_00]: and yet, even with that structure, the atmosphere remains.
[SPEAKER_00]: The scale of the entrance and the sound of the water, the darkness beyond the lit pathways, all still present, and for many people.
[SPEAKER_00]: There is still a moment standing at the threshold, looking inward, where the cave feels less like a place to explore.
[SPEAKER_00]: A more like a place that exists on its own terms.
[SPEAKER_00]: The story of the devil's arse isn't about lictual belief, it's about interpretation, about how people respond to environments that feel unfamiliar, uncontrolled difficult to explain.
[SPEAKER_00]: The name itself crude, memorable, impossible to ignore is a way of making sense of that experience,
[SPEAKER_00]: And even as the name changes, the underlying reaction remains, because the cave still feels the same.
[SPEAKER_00]: It still sounds the same, it still holds the same presence.
[SPEAKER_00]: Pete Cavan, in one sense, a geological formation, carved by water and shaped by time, explainable and measurable.
[SPEAKER_00]: But in another sense, it is something else.
[SPEAKER_00]: A place where sound becomes meaning, where darkness invites interpretation, where the landscape feels, not empty,
[SPEAKER_00]: of a generation's name given to it reflected that meaning.
[SPEAKER_00]: Not polite, not scientific, but direct, human, and unforgettable.
[SPEAKER_00]: Because sometimes the way in name a place tells us more about ourselves than the place itself.
[SPEAKER_00]: You've been listening to Hidden Darbyshire, folklore and legends.
[SPEAKER_00]: Next time we leave the caves behind, and step into one of Darbyshire's grandest houses, where history and reputation into twine, and where one woman's story may still linger in the halls.
