10 Famous Irish Saints

The Dark Ages descended on Britain after the fall of the Roman Empire and caused many scholars and Christians to flee to Ancient Ireland (also known as Hibernia) as pagan beliefs began to return Britain to a society of warfare and clan revival.

In Ireland however, a new age was dawning and the country became known as the Land of Saints and Scholars. Ireland began to be the centre of Christianity and a growing culture of monks and the church. This is my list of my favourite 10 famous Irish saints and how to follow in their footsteps and visit where they preached, where they are buried and what they represent.

Among the most famous saints of Ireland is of course St. Patrick who is one of Ireland’s official patron saints. There are actually three patron Saints of Ireland these include Saint Brigid, Saint Columba (Saint Colmcille) and of course St. Patrick.

Ireland’s Patron Saints

Saint Patrick – March 17th

Everyone knows Saint Patrick and his most famous legend – that of driving the snakes out of Ireland. St. Patrick first came to Ireland as a slave and when he escaped slavery he is thought to have returned to Ireland to bring Christianity to the island. St. Patrick is the most important patron saint of Ireland.

Irish folklore credits Patrick with teaching the doctrine of the Holy Trinity by using a shamrock to illustrate the three persons in one god.

Famous Irish saints

Saint Brigid – February 1st

Brigid is Ireland’s only female patron saint and she was born around 451AD in County Louth the daughter of the King of Leinster and a Pictish slave who had been baptized by St. Patrick.

In pre-Christian mythology, there was a Goddess Brigid who held many of the same traits attributed to the Christian Brigid and it is likely that the two became conflated in order to Christianize the pagans.  Interestingly St Brigid’s feast day falls on the pagan festival of Imbolc or the arrival of spring.

Famous Irish saints

The stories of Brigid tell of how she prayed for her beauty to be taken away so she wouldn’t be marriageable and could become a num to take care of the poor.

On St. Brigid’s day, the Irish weave a rush cross which they place over their doors. This more than likely harks back to pagan celebrations where they wove these “crosses” to protect their homes from fire.

Famous Irish saints

Saint Brigid established her convent Cill-Dara in Kildare around 479AD and also founded a school of art that created the Book of Kildare a famous illuminated manuscript.  According to legend, she chose the spot as it was where a shrine to the Irish goddess Brigid was located. An eternal flame on the shrine was regularly tended to by a group of young women.

St Brigid’s Holy Well

The well is fed by a spring that flows underground before appearing again under a stone archway. The stones below the archway are known as St Brigid’s slippers. The stream then flows past a modern bronze statue of Saint Brigid. There is a tree nearby covered in what are called “clooties” these are rags left by folks who believe that if they hang a piece of cloth from a troubled or ill person the problem will disappear as the rag disintegrates.

Famous Irish saints
The Curragh – Kildare

The Curragh is known as St. Brigid’s Pastures. According to legend, it was granted to St. Brigid by the King of Leinster in return for reducing the size of his ears. Having agreed to settle for a portion of land that her cloak would cover, Brigid threw down her cloak and it spread until it encompassed the whole Curragh (5,000 acres).

St. Brigid’s Cathedral & Round Tower – Kildare

This Cathedral is said to be built on the original site of St. Brigid’s church which was established under an oak tree. The modern Cathedral was almost completely rebuilt in the late 19th Century. The building contains Ireland’s Highest accessible Round Tower built in the 12th century and the remains of St. Brigid’s eternal flame was kept by her Sisters until the time of the reformation.

Famous Irish saints

Saint Colmcille –  9th June

Columba was born in Donegal in the 5th Century and was said to be able to trace his ancestry to Niall of the Nine Hostages, the legendary Irish High King. His Irish name was Colmcille and he travelled as a monk over the north of Ireland. St. Colmcille is the city of Derry’s patron saint.  When he was at Clonary Abbey he got into an argument with Finian around his copying of a manuscript without permission. But Finian said that this was theft–illegal copying! He demanded that Columba hand over the copy he had made.

Famous Irish saints

King Diarmait mac Cerbhiall, the High King of Ireland, decided between the two of them that the copy of the book belonged to Finian. Columba believed that “It is not right,” he said, “that the divine words in that book should perish, or that I or any other should be hindered from writing them or reading them or spreading them among the tribes.”

But the king ruled against him saying, “To every cow belongs its calf; to every book its copy.” In other words, every copy of a book belonged to the owner of the original book.

Sadly the two continued to argue Columba committed another crime by hiding a fugitive from the King resulting in the Battle of Cúl Dreimhne, where over 3000 died and Columba was exiled as a result.

He was so guilt-stricken that he swore never to return to Ireland and sailed for Scotland where he would attempt to convert the Pictish pagans.

This church appears to contain some fragments of the Augustinians’ buildings. On the east side of the doorway, visitors can see a carved limestone head that dates from the Middle Ages. The small belltower at the northwest corner of the church has the same proportions as one from the 1200s.

Kevin lived the life of a hermit in a cave, his friends were the animals and the birds and he preferred a solitary life away from his followers. He was a hermit for 7 years, went barefoot and ate very little. By 540, his fame had spread far and wide and his followers came to Glendalough and developed a seminary and monastery in his name.

His body was buried in two boxes but the remains were exhumed in 1683 and moved to a Benedictine Monastery in Germany. Eventually, his head was brought to Rome and then moved to Armagh and from there it was rested at Saint Peter’ Church.

St. Buíthe – no feast day

Monasterboice is near Drogheda, and it was founded in the 5th century by St. Bhuithe, one of St. Patrick’s original followers. Today the ruins are known for one of Ireland’s best collections of high crosses, in particular, The South Cross or Cross of Muiredach, the Tall Cross or the West Cross.

Monasterboice high crosses and Norman Tower

There is evidence at Monasterboice that prior to its ‘founding’ by St. Bhuithe in the late 5th century is said to have been a significant place for pagan Celts. Vikings captured the settlement in 968 AD and were expelled by Donal, the Irish high king of Tara. St. Bhuithe’s Monastery was an important centre of spirituality and scholarship until the Cistercians arrived at nearby Mellifont Abbey in 1142, after which Monasterboice became neglected.

visiting Monasterboice

Monasterboice has many interesting features to explore, but the clear highlight is its superb10th century high crosses. Like murals and church sculptures, these magnificent examples of Celtic art brought the Bible to life for those who could not read (which was most people).
