Fairies in Irish and Scottish Lore: Names, Types and Sites

Article Summary

What this article covers: The names, origins, types, powers and protective customs behind fairies in Irish and Scottish lore, plus the mounds, forts, trees and glens you can still visit.

Who this is for: Travellers who want the folklore behind the sites in Ireland and Scotland, readers researching Celtic heritage, and anyone separating real Gaelic tradition from Victorian invention.

Key takeaway: In fairies in Irish and Scottish lore the beings were never small and winged. They were the dispossessed gods of Ireland, living inside prehistoric mounds, and the customs around them existed to keep people at a distance.

Expert insight: “I’ve stood at the Fairy Glen in Rostrevor on a wet Tuesday in November with nobody else about, and you understand the lore differently there. The light comes through the trees in a way that makes the ground look like it is moving. Nobody in that valley ever told me a story about wings or wands. What they told me was where not to walk.” , Ciaran Connolly, Founder of ConnollyCove

Quick facts:

• The Irish word sídh means a mound, not a creature; the beings are the aos sí, the people of the mounds
• In Irish and Scottish Gaelic, the root word for fairy is also the root word for peace
• The National Folklore Collection at University College Dublin holds thousands of fairy accounts gathered from Irish schoolchildren between 1937 and 1939

Ireland and Scotland share a body of fairy belief that has almost nothing to do with the creatures most people picture. There are no wings. There is very little sparkle. What there is instead is a set of rules about land. Which mounds you leave alone, which trees you never cut, which paths you do not build a house across. Fairies in Irish and Scottish Lore were neighbours who had got there first.

That distinction matters if you are travelling. Ireland has tens of thousands of earthworks scattered across its farmland, and plenty are still left untouched by farmers who would tell you they are simply not worth the trouble. Our guide to Irish mythological creatures runs through the individual beings in more detail.

ConnollyCove covers this material because it explains the physical country you are looking at. What follows is what the tradition actually says about fairies in Irish and Scottish lore. The Gaelic names. The origin story that turns gods into mound dwellers. The types and the powers attributed to them. The darker figures most articles skip. The protective customs. And the sites you can go and stand in.

What Fairies Are Called in Irish and Scottish Gaelic

The most useful thing to know about fairies in Irish and Scottish lore is that the word people search for is not the word the tradition uses. Both languages describe these beings by where they live rather than what they look like. Once you know that, much of the older material stops being confusing.

The Mound and the People

Sídh (also written síd, and sídhe in the older orthography) is an Irish word for a mound or hill. It means the kind of prehistoric burial mound found across the Irish countryside. The beings themselves are the aos sí, the people of the mounds, or the daoine sí, which means much the same. Using “sidhe” alone as a name for the fairies is a nineteenth-century English habit rather than correct Irish, though it is now everywhere.

Scottish Gaelic runs in parallel. Sìth is the fairy, sìthean is the fairy knoll, and daoine sìth are the fairy folk. The vocabularies diverged after Gaelic speakers carried the tradition from Ireland into Argyll. The underlying idea did not change.

Why the Root Word Also Means Peace

In Scottish Gaelic, sìth means both fairy and peace. Irish keeps a related sense in its words for quiet and stillness. This is not a coincidence and it is not sentimental. Calling a dangerous entity “the peaceful one” was insurance. The same logic produced na daoine maithe, the good people, and the Scots phrase “the good neighbours”.

Names People Avoided

Direct naming was avoided in both countries. Accounts from Irish country people use “them”, “the other crowd”, “the gentry” and “the good people” in place of any specific word. Naming something attracts its attention, and much of the etiquette in fairies in Irish and Scottish lore follows from that idea.

Where the Fairies Came From

Fairies in Irish and Scottish Lore begin as gods. The origin story is not vague or lost. It is written down in medieval Irish manuscripts, and it explains almost every feature of the later folklore, including why the fairies live underground.

The Tuatha Dé Danann Go Under the Hills

The Lebor Gabála Érenn, usually translated as the Book of Invasions, sets out a sequence of peoples who settled Ireland. Among them are the Tuatha Dé Danann, a skilled and god-like race. They ruled the island until the arrival of the Milesians, presented in the text as the ancestors of the Gaels. On defeat, in the version that carried into folklore, they withdrew into the mounds rather than leaving.

That withdrawal is the hinge of the whole tradition. Gods who once held Tara became the hidden population of the passage tombs and ringforts. We cover the fuller narrative in the legends of the Tuatha Dé Danann.

The individual figures appear in our guide to the Celtic gods and goddesses of ancient Ireland.

What Christianity Did to the Story

Christian scribes did not delete the older beings. They demoted them. One widespread folk explanation held that the fairies were angels who fell, but were not bad enough for hell, so they were left in the middle. That let people keep the tradition intact inside a Christian worldview, which is much of why it survived.

How the Tradition Reached Scotland

Gaelic-speaking settlers moved from the north of Ireland into western Scotland, and the lore travelled with the language. Over the following centuries the Scottish material picked up its own character. More water beings, more mountain and sea settings, and eventually a court system Ireland never developed.

Our piece on Gaelic Ireland covers the language history behind that spread.

Types of Fairies and the Powers Attributed to Them

Fairies in Irish and Scottish Lore were sorted less by species than by behaviour, and the most durable classification is the simplest. W. B. Yeats, collecting Irish tales in the 1880s, split them into the trooping fairies who move in groups and the solitary fairies who keep to themselves. That division still holds up.

Trooping and Solitary

The trooping fairies are the ones associated with music, processions, dancing and the great fairy hosts. People claimed to hear them rather than see them. The solitary fairies are individuals with a trade or a fixed role: the leprechaun as shoemaker, the clurichaun, the far darrig. Both groups appear throughout fairies in Irish and Scottish lore.

We have a longer treatment of leprechauns in Irish folklore, including how much of the modern version is Victorian and American invention.

What They Were Said to Be Able to Do

The powers attributed to fairies are consistent across both countries. They are mostly about perception and boundaries rather than force. Fairies were said to make themselves unseen and to alter how a place looks. They could lead a traveller in circles on ground he knew perfectly well. They could take a person or a child and leave something in their place. They could bless or blight livestock and crops.

Music and skill were their gifts to people. The recurring price was time. Those who accepted fairy hospitality came back to find years had passed.

The Water Beings of Scotland

Scotland contributes the strongest water lore, and this is where fairies in Irish and Scottish lore diverge most visibly. The each-uisge, the water horse of the Highlands, was the most feared, said to carry riders into deep water. The kelpie belongs to rivers and burns. The selkies of Orkney, Shetland and the Hebrides are seal people who come ashore in human form. Selkie stories are unusual in the tradition for being genuinely sad rather than frightening.

Our overview of legendary creatures in Celtic mythology sets these alongside their Irish counterparts.

The Darker Figures Most Guides Skip

Popular coverage of fairies in Irish and Scottish lore tends to stop at banshees and leprechauns. The tradition goes considerably further, and the darker material is where the belief system shows what it was for. These were not stories told for entertainment. They explained sudden death, illness in children and cattle, and people who went missing.

The Sluagh

The sluagh is the host. In Scottish Highland tradition the sluagh are the spirits of the unforgiven dead. They travel in the air in great flocks, and were said to come at a dying person’s window. Some accounts have them carrying the living away. It is one of the few parts of the lore with a practical instruction attached: keep the west-facing window shut.

The Bean Sí

The bean sí, anglicised as banshee, means woman of the fairy mound. She is not a general omen of death but a family one, attached to particular Irish families. Her keening announces a death rather than causing it, and it connects her to a real practice: the professional mourning women who cried the dead at Irish wakes. She belongs to the fairy population by name, which is why she keeps appearing in fairy lists.

Changelings and What They Explained

The changeling belief held that fairies might take a healthy child and leave one of their own in its place. Iron objects were put over cradles as protection. This part of fairies in Irish and Scottish lore deserves to be treated seriously rather than as colour, because it had consequences. In 1895, in Ballyvadlea, County Tipperary, Bridget Cleary died after her family tried to drive out what they believed was a fairy substitute. The case went to trial.

Rules of Engagement: Iron, Rowan and the Red Thread

The protective customs are the most consistent element across both countries. They are also the part that survived longest in living memory. Fairies in Irish and Scottish Lore came with a working code of conduct, and that code was about avoidance rather than confrontation.

What People Carried and Left Out

Cold iron was the standard deterrent. A nail, a horseshoe over a door, a pair of scissors above a cradle. Rowan was the protective wood in both Ireland and Scotland, often tied with red thread, and red thread alone turns up in Scottish charms for protecting cattle. Gifts ran the other way: milk poured at the base of a tree or on a flat stone, or the first of the churning left out.

Our guide to sacred trees in Celtic beliefs covers the wider tree lore this belongs to.

What People Never Did

The prohibitions are more revealing than the charms. You did not eat fairy food. You did not give your full name if addressed. You did not thank them directly. You did not cut a lone hawthorn. And you did not build across a path understood to be theirs. That last rule in fairies in Irish and Scottish lore is still occasionally live, and road schemes have been rerouted around fairy trees within living memory.

Fairy Sites You Can Visit in Ireland and Scotland

This is the part of fairies in Irish and Scottish lore you can actually stand in. Most of the sites are free. Most sit on public land or accessible paths. Almost none of them are marked as fairy anything.

Fairy Forts and Mounds

The Irish fairy fort is usually a ringfort, a circular earthen enclosure that archaeologists date to the early medieval period and read as a farmstead. There are tens of thousands recorded across the island. Folklore reassigned them to the fairies, which is much of why so many survive intact in working fields. The passage tomb complexes are the high-status version: Brú na Bóinne, the Hill of Tara, Knocknarea and Rathcroghan.

Our guide to fairy forts and their folklore in Ireland sets out how to recognise one in the field.

Fairy Trees and Glens

A lone hawthorn standing in the middle of a field, left unploughed and unpruned, is the classic Irish fairy tree. Once you have seen one you notice them from the car. We cover the tradition in detail in our guide to fairy trees in Ireland.

For somewhere to walk, the Fairy Glen at Rostrevor in County Down is a river valley at the foot of the Mournes with a marked path. There is a well-known glen of the same name on Skye, and Scotland’s sìthean mounds are scattered through the Highlands and Islands, rarely signposted.

Visiting Without Being a Nuisance

Two things worth saying plainly. Most fairy forts sit on private farmland, so ask, and do not climb a fence. And tying ribbons or hammering coins into trees at these sites is modern. It damages the trees and forms no part of the older customs. Leaving nothing is closer to what the tradition asked for.

Ireland’s Otherworld destinations connect to the wider idea of Tír na nÓg if you want to follow that thread.

How the Irish and Scottish Traditions Differ

Most writing on fairies in Irish and Scottish lore treats the two countries as one body of material. They are closely related, but not identical, and the differences are the most useful thing a comparative guide can offer.

The Courts Are Scottish, Not Irish

The Seelie and Unseelie Courts, the division of fairies into a benevolent faction and a malevolent one, is a Scots classification. “Seely” is an older Scots word for happy, blessed or lucky. The court framing was popularised through nineteenth-century Scottish collections. Irish tradition has no equivalent split. Irish fairies are dangerous, neutral and self-interested by default rather than sorted into good and bad camps. Any article applying Seelie and Unseelie to Irish material has imported a Scottish idea.

Land, Water and Language

Irish lore anchors to mounds, ringforts and the old royal sites, and its central figures are the aos sí and the bean sí. Scottish lore leans towards water and high ground: the each-uisge in the lochs, the selkies on the shore, the sluagh in the air over the hills. Vocabulary tracks the same split, with Irish sídh and Scottish sìthean both meaning mound.

Our piece on the Celtic nations covers how the two traditions relate across the wider Gaelic world.

Whether Anyone Still Believes

Fairies in Irish and Scottish Lore are not a closed subject, and the honest answer is that the customs outlived the belief. Very few people in Ireland or Scotland today would say they believe in the aos sí. Considerably more would decline to cut down a lone hawthorn.

You can check the evidence yourself. The National Folklore Collection at University College Dublin has digitised the Schools’ Collection, gathered from Irish schoolchildren between 1937 and 1939. It is searchable by parish at dúchas.ie, and reading accounts from your own family’s area is the closest thing to hearing the tradition directly.

The Scottish equivalent is the School of Scottish Studies sound archive, available through Tobar an Dualchais. There you can hear Gaelic speakers describing fairy encounters in their own voices.

Planning a Trip Around the Fairy Sites

Fairies in Irish and Scottish Lore make more sense on the ground than on the page. Start with the mounds, the origin point of the whole tradition, then look for the lone hawthorns on the drive between them. ConnollyCove covers Irish heritage, Celtic mythology and travel destinations to help travellers understand the places they are standing in.

Our ConnollyCove YouTube channel has video guides to several of the sites above.

For more on the beings themselves, our guide to the Sidhe and Irish folklore picks up where this one leaves off.

Ciaran Connolly founded ConnollyCove to connect this kind of cultural detail to real journeys. Our collection of Irish proverbs shows how much of it survives in everyday Irish speech.
