Lá Fhéile Bríde · 1 February

St Brigid's Day

Ireland's second patron saint, and the only one whose day is a public holiday. Brigid of Kildare founded a monastery of women and men together, gave her name to a perpetual fire that burned for centuries, and shares her feast and her attributes with a goddess of the same name. Her cult is documented earlier and more fully than almost any in Ireland; her biography is another matter, and how the saint and the goddess relate is a question the sources do not settle.

There are two Brigids
The story, as far as it can be told
  1. c. 451 — Born, by tradition
    The medieval lives give her a chieftain father and an enslaved Christian mother, and a fostering in a druid's household. None of it is contemporary evidence; all of it is the story the Middle Ages told.
  2. c. 480 — Kildare founded
    Cill Dara, the church of the oak. Her monastery was a double house of women and men under an abbess, unusual anywhere in Europe, and Kildare became one of the great churches of Ireland.
  3. c. 525 — Died, by tradition
    Her feast was being kept by the Middle Ages, though the customs attached to it are not recorded in detail until the early modern period.
  4. c. 878 — The relics move
    With Viking raids on Kildare, Brigid's relics were said to be taken to Downpatrick and reburied in the tomb of Patrick and Colmcille — which is how Ireland's three patrons came to share one hill.
  5. 1185–86 — Found and reburied
    John de Courcy was said to have found the three saints' relics, and reburied them solemnly in Down Cathedral on 9 June 1186.
  6. 1538 — Destroyed
    The relics were desecrated during the deputyship of Lord Grey — all but Brigid's head, which clergy carried to a Franciscan house at Neustadt in Austria, and which was presented to the Jesuit church in Lisbon in 1587.
  7. 1993 — The fire relit
    A perpetual fire burned at Kildare in her honour for centuries. It was lit again in 1993, and it burns still.
  8. 2023 — A public holiday
    Her feast became a public holiday in the Republic — the first Irish public holiday named for a woman, and the first new one in nearly fifty years.
What people do on the day
Why it falls on 1 February Because Imbolc does. Imbolc is one of the four Gaelic quarter days with Bealtaine, Lughnasa and Samhain, falling halfway between the winter solstice and the spring equinox, and it marks the start of spring and the lambing. Historians take it to be pre-Christian, associated with the season and quite possibly with the goddess. The Christian feast was laid on top of a day that was already being kept.
How to read the miracles The Lives are full of wonders — cloaks spread over ground to claim it, a vat of ale from one measure of malt, cows that yield three times in a day. It is tempting to read these as pagan material barely dressed up, and some of it may be. But the forms are also the ordinary forms of hagiography as it was written across Christendom at the time, and miracles of plenty and of protection are what a seventh-century Life was for. Treating every wonder as a survival from an older religion is an interpretation, not a finding, and a reader should know which of the two they are being handed.
The Mary of the Gael One of her titles, alongside “the Mary of Ireland” and “the Mother Saint of Ireland”. Her name travelled further than she did: Middle Irish Brigit became Brighid and, after the spelling reform of 1948, Bríd — and through Medieval Latin Brigida it gave English Bridget, French Brigitte, Swedish Birgitta and Finnish Piritta. In Welsh she is Ffraid, which is why Wales has villages called Llansanffraid.
She shares the day 1 February is also the feast of Dar Lugdach, who tradition makes her student, her close companion and her successor as abbess of Kildare. She is rarely mentioned outside the calendars, and she is on the same page of them as Brigid.
Quick answers
When is St Brigid's Day?

1 February — Lá Fhéile Bríde. Since 2023 it has been a public holiday in the Republic of Ireland, the first named for a woman. It falls on the old festival of Imbolc, the start of spring in the Gaelic year.

Was St Brigid a real person?

Historians differ, but the question is more finely balanced than it is often put. Verifiable biography is scarce — the Lives are collections of miracles rather than records. Documentation of her cult is not scarce at all: two Old Irish hymns from the 7th century, two Latin Lives from the 7th to 8th centuries, one of them by Cogitosus of her own Kildare, a vellum fragment bearing her name from about 700, and the Old Irish Bethu Brigte in the 9th. Some scholars hold the saint is a Christianisation of the goddess of the same name; others that a real abbess existed and the lore attached itself afterwards.

Who was the goddess Brigid?

A member of the Tuatha Dé Danann, daughter of the Dagda, associated with poetry, healing, smithcraft, protection and livestock. Cormac's Glossary, written by monks in the 9th century, calls her the goddess whom poets adored and gives her two sisters of the same name, a healer and a smith, which is usually read as one deity in three aspects.

Why is a St Brigid's cross made of rushes?

Rushes are what grew to hand in a wet field in February. The cross is hung over a door or window to protect the house from fire, illness and harm, and it is remade each year — the most commonly practised piece of folk custom left in Ireland.

What is Imbolc?

One of the four Gaelic seasonal festivals, with Bealtaine, Lughnasa and Samhain, falling on 1 February about halfway between the winter solstice and the spring equinox. It marks the beginning of spring and the lambing season, and historians take it to be pre-Christian in origin.

Is the fire at Kildare still burning?

A perpetual fire was kept in Brigid's honour at Kildare for centuries. It was lit again in 1993 and burns there now.

Why is St Brigid's Day a public holiday?

It was made one in the Republic from 2023, the first new public holiday in nearly fifty years and the first named for a woman. It is taken on the first Monday in February, except when 1 February is itself a Friday.
