Leap Castle: The Elemental, the Bloody Chapel, and the Oubliette Full of Bones

In the middle of Ireland, in County Offaly, on a rise of ground that commands the old pass between the Slieve Bloom Mountains and the plain, there is a gray tower house that has been standing there in one form or another since the fifteenth century. It is not large as castles go. It is not beautiful. It sits at the end of a lane with fields around it, and there is no moat and no fairy-tale turret, and if you drove past it without knowing you would take it for what it mostly is: an old Irish keep, half-ruined, patched, lived in.

It is also, by a fairly wide margin, the most frightening building in Ireland, and the reason has nothing to do with atmosphere. It has to do with what was found under the floor.

The Pass and the Family

Leap Castle was built by the O'Bannons, and then it came to the O'Carrolls, and it is the O'Carrolls who matter.

The castle sits on a strategic pass, and whoever held it held the road. The O'Carroll clan held it through the bloodiest centuries Ireland ever had, and they held it the way it was held in those centuries: by killing anyone who wanted it, including each other. When the chieftain Mulrooney O'Carroll died in 1532, the succession went the way successions went, and the family tore itself apart. Brother against brother, in and around that tower.

Which brings us to the room at the top.

There is a chapel on the upper floor of the main tower. In 1532, during the fighting over the succession, one O'Carroll brother — a priest, saying Mass at the altar of that chapel, in front of his own family — was run through by his brother's sword. He died on the altar, in his vestments, in the middle of the rite.

The Irish do not name rooms lightly. That room has been called the Bloody Chapel for five hundred years.

What They Found in 1922

The castle burned in 1922, in the Civil War, and the family that owned it then — the Darbys — set about clearing the ruin. And in a corner of the Bloody Chapel, behind a wall, the workmen found a small door.

Behind the door was a shaft. It was an oubliette — from the French oublier, to forget: a chamber with no exit, into which a man is dropped and then not thought about again. The bottom of Leap's oubliette was fitted with wooden spikes set upright, so that anyone thrown in either died on the spikes at once or, more likely, was impaled through the body and left to die slowly at the bottom of a stone chimney in the dark, within earshot of the chapel above.

The workmen took three cartloads of human bones out of that shaft. Three cartloads. The estimates run to well over a hundred people, and there is no way to count them properly, because they had been going in for centuries and had settled into one another. Among the bones they found a pocket watch, made in the 1840s, which tells you that the oubliette was still receiving deposits within living memory of the people clearing it.

There is a story that the O'Carrolls invited a rival clan, the McMahons, to dine at Leap as guests, having hired them as mercenaries, and murdered them at the table over the meal. The Irish had a name for that particular crime, and it was not merely murder. To kill a man who has eaten your bread under your roof is the one offense that the old world, in every culture that had a word for hospitality, regarded as beyond forgiveness.

The Elemental

Then there is the thing that is not a ghost.

The Darby family lived at Leap in the nineteenth century, and Mildred Darby, the mistress of the house, was interested in the occult in the fashionable Victorian way. In the 1900s she began, by her own published account, to dabble — to hold séances, to attempt to raise what could be raised, in a castle whose chapel had a wall full of bones behind it that nobody yet knew about.

She woke something.

What she described, in print, in 1909, is worth quoting the substance of, because it does not read like the standard Victorian ghost. She said she was standing in the gallery when she felt two hands on her shoulder, and she turned, and it was there, close enough to touch. She described a thing about the size of a sheep, gray, with a human-ish face, black holes for eyes, and a smell — and the smell is the detail that everyone who has ever encountered it comes back to. A stench of rotting flesh and sulphur that fills the room and then is gone.

It has been seen since, repeatedly, by people with no stake in it and no knowledge of Mildred Darby's article. Sean Ryan, the musician who bought the castle in 1991 and has lived in it since with his family, has spoken about it with a remarkable Irish matter-of-factness. He is not a ghost hunter. He restored the place by hand and lives there and gives tours, and when asked about the thing he says, in effect: yes, it is there, we came to an arrangement.

It is called the Elemental. That is not a word Irish folklore uses casually. A ghost is a dead person. An elemental is not, and never was, a person at all.

An Esoteric Reading

Here is where Leap Castle stops being a scary building and becomes a lesson, and the lesson is precise.

The old traditions divided the unseen world with far more care than we do. There is the shade — the human dead, lingering, and every one of them was once somebody's son. Shades are pitiable. They repeat. They want something. You can pray for a shade.

And then there is the other category, which the Irish knew and the Greeks knew and every tradition of the West knew: the thing that was never human. The Latin authors called them genii loci when they were benign and something rather worse when they were not. The Irish had a whole taxonomy for what lives in a rath, a mound, a boundary, a ford — and the first rule of every one of those traditions is that these beings are not moral. They are not good or evil in our sense any more than a river is. They are of the place. They are the place, awake.

An elemental, in the strict old sense, is the character of a piece of ground given force and appetite. And what the traditions say about them, with total consistency, is this: ordinarily they sleep. Ordinarily the ground is just ground. What wakes them is what is done on them.

Consider, then, what was done on this ground. A priest killed at the altar in the middle of the Mass — which is not one profanation but three at once: the murder of a brother, the murder of a priest, and the desecration of the rite at the moment of consecration. Guests murdered at the table under the roof that had accepted them, which is the breaking of the hospitality-bond that every ancient people held to be enforced by the gods directly. And beneath the floor of that same chapel, a shaft in which men were dropped onto spikes and forgotten, for four hundred years, so that the Mass was said — when it was said at all — directly above a pit of people dying slowly in the dark.

The alchemists taught that what you seal in the vessel is what you get out of it. Leap Castle is a stone vessel that was sealed for four centuries with murder, sacrilege, betrayal, and the deliberate forgetting of the dead, and the heat under it never went out. Something coagulated in there. And it is not any one of the O'Carrolls, because it is not a person. It is the sum. It is what four hundred years of that becomes when it is packed into one small tower and given time.

And then a Victorian lady with a séance table sat down in the middle of it and started calling.

This is the error the old books warn about on nearly every page, and it is always the same error: the operator assumes that because she is calling politely, she will be answered politely. Mildred Darby thought she was doing what fashionable people did in drawing rooms in Dublin. She was doing it in the one room in Ireland where it should never have been done. She lit a fire under a vessel that had been quietly sealed for four hundred years, and the thing that had been condensing in there since 1532 came up the stairs and put its hands on her shoulders.

Note the smell. This is not a decorative detail. In the entire literature of the West, from the desert fathers to the Roman rite, the one sign that is reported with the most stubborn consistency is the stench — the sudden reek of putrefaction and sulphur where there is nothing to rot and nothing to burn. Every tradition treats it as the signature of a thing that is present in the flesh rather than merely seen. The eye can be fooled. The nose, they held, cannot be.

The bones came out in 1922 and were given Christian burial, and that is the single most important thing anyone has ever done at Leap Castle. It is the correct rite: name what you can, bury the rest, close the pit. And by every account it did help. It did not finish. The Elemental is not a shade and cannot be laid by a funeral, because it never had a body to bury. You cannot exorcise a place's character. You can only stop feeding it.

Sean Ryan lives there now with his family, and by his own telling he does not fight it and does not court it. He plays the flute in the great hall. He has, he says, an understanding with whatever is upstairs. The old traditions would recognize that exactly: you do not defeat the genius loci. You come to terms.

The tower is still there at the end of its lane, with the chapel at the top and the empty shaft behind the wall, and the fields around it are as green and as quiet as any in Ireland. The bones are gone. The smell comes back.
