Why Irish Families Once Sealed Every West-Facing Window When Someone Was Dying

When someone was dying in an old Irish home, the family didn’t just grieve. They moved quickly. West-facing windows were sealed shut. Doors facing the setting sun were bolted or covered. This wasn’t about draught or cold. They were keeping something out.

That something had a name. The Sluagh.

Ireland’s Most Feared Night Visitors

The Sluagh (pronounced sloo-ah) were not like the fairies of popular imagination. They weren’t mischievous little figures or beautiful supernatural beings.

They were the restless, unforgiven dead — souls so burdened by the wrongs of their earthly lives that neither heaven nor the fairy realm would receive them.

Denied peace and denied rest, they gathered into a vast, dark host. They swooped and wheeled through the night sky like enormous flocks, always moving against the wind. Their approach brought a terrible rushing sound — part wind, part wail — that people recognised with dread.

No creature in Irish folklore inspired more genuine fear among the people of the west of Ireland — not even the banshee, whose cry at least gave warning. The Sluagh gave none.

Why the West Was Always the Danger

In Irish tradition, west is the direction of death. The sun sets in the west. The great Atlantic stretches away into darkness on that side. The mythical land of the dead — Tír na nÓg — lies somewhere beyond the western horizon.

The Sluagh knew this geography. They always flew in from the west. This is precisely why west-facing windows were the point of danger in any house where someone lay dying.

Every home had them. And every family understood that as death drew near, the west side of the house had to be sealed. A soul departing the body near an open west window could be swept away before it had any chance to rise in peace.

What the Sluagh Could Do to the Living

Their power was not limited to the dying. The Sluagh were also said to seize the living — those caught outdoors at night, alone, without iron or light.

A person taken by the flock might be carried across the countryside against their will. Some accounts held that the Sluagh could force such a person to shoot fairy arrows at cattle or at neighbours. The person would wake the next morning, bruised and exhausted, with no memory of the night.

The livestock would be found dead in the field with no visible wound.

Mysterious illness, cattle that sickened overnight, people who woke shaking and couldn’t say why — all of this was laid at the door of the Sluagh in the west of Ireland, particularly in counties Galway, Clare, and Mayo.

How Families Tried to Hold Them Back

The sealing of west-facing windows was the oldest and most important defence. But it was not the only one.

Iron was universally held to repel fairy creatures, and the Sluagh were no exception. Old iron implements — a horseshoe, a pair of tongs, a knife — placed across a threshold or windowsill would slow or stop them.

Some families lit candles on the west side of the house throughout the dying hours, trusting that firelight would disorient the flock. Others recited particular prayers or verses, though the Sluagh — as the souls of sinners — were considered beyond the reach of ordinary blessing.

Dying outdoors was considered extremely dangerous. So was being near an open west window at the moment of death. A soul caught mid-departure — still half-tethered to the body — was considered easy prey. Those in isolated houses along the western seaboard were thought most at risk of all.

When the Last Memories Were Gathered

The Sluagh are rarely spoken of today. Unlike the banshee or the leprechaun, they never made it onto tourist souvenirs or gift shop shelves.

But the older generation in the west of Ireland remembered them clearly well into the 20th century. The great folklore collection of the 1930s, when schoolchildren across Ireland were sent to record the stories of their grandparents, gathered accounts of the Sluagh still circulating in counties Clare, Galway, and Mayo.

In those accounts, the Sluagh were never treated as metaphor or legend. They were described as a real, nightly danger, to be guarded against with practical measures.

The tradition of sealing west-facing windows at a death lingered in some households long after the name “Sluagh” had been forgotten. The habit outlasted the belief that created it. And the customs that surrounded death in Ireland were always more layered than most outsiders ever imagined.

Irish folklore is full of strange and beautiful beings. The Sluagh are different. They carry a very human fear: the dread of a life poorly lived, of dying without peace, of being refused rest.

When Irish families sealed their windows against the western dark, they were doing something deeply human. Protecting what they loved. Holding the door against the worst that the night could bring.

In the old faith, that was worth taking seriously. Some would say it still is.
