Croagh Patrick, Westport in Co. Mayo

Blog Header Image

Croagh Patrick, or "The Reek", as it is known locally, is situated 9 km west of Westport on the Louisburgh road, above the village of Murrisk. It is one of Mayo's most famous landmarks, soaring to a height of 765 metres. The mountain overlooks Clew Bay and the entire western coastline and is particularly associated with Ireland's patron saint, St Patrick.

It was originally called Cruachan Aigli. Cruachan means conical mountain, while Aigli means eagle and indicated the overall area too.

Croagh Patrick is the Holy Mountain for Irish people. According to traditions and accounts, in 441 AD, St Patrick spent the 40 days of Lent praying and fasting on the mountain top as part of his effort to convert Ireland to Christianity, following the example of Christ and Moses. Here, St Patrick is credited with driving snakes, demons and magicians out of Ireland, hurling them into the Demon’s Hollow or Log na nDeamhan, a lake at the north base of Croagh Patrick. It is said it burst up because of St Patrick’s powerful gesture.

Since then, it has been the focus for pilgrimage and, nowadays, thousands of people still climb the Holy Mountain on the last Sunday of July or “Reek Sunday”; some of them stops at the Stations of the Reek and walks around or kneels at the stone cairn and prays.

The Stations evolved over the centuries. Nowadays, there are three stations. The first station takes place at the Statue of St. Patrick, a few hundred metres up the mountains. Traditionally it took place at Leach Benin (Benin’s stove or grave, named after Benin, one of St. Patrick’s disciples. The second is located on top of the mountain at Leaba Phádrag (Patrick’s Bed). The third one is located at the foot of the Holy Mountain on its western shoulder and is known as Reilig Mhuire (Our Lady’s Cemetery).

The 19th-century writer William Thackeray in his travel book, “The Irish Sketch Book” (1842), described the site as ‘three stone heaps’. Today we know the three stone heaps are Bronze Age cairns or burial sites.

The tradition of the pilgrimage goes back in time, though.

When the Holy See opened its archives and library during the papacy of Pope Leo XIII (1878-1903), some historians were sent to find all documents about Ireland buried within the Vatican.

The Irish historian William Henry Grattan Flood discovered a document issued by Pope Eugene IV in 1432 regarding the Croagh Patrick pilgrimage.

In this statement, dated September 27th 1432, the Pope granted an indulgence of two years and two quarantines to the Archbishop of Tuam for the people who visited and gave donations to repair the structure of the oratory of St Patrick on top of Croagh Patrick.

Indulgences were to be gained on a Sunday before the Feast of St Peter’s Chains celebrated on August 1st.

Archbishop Healy took the statement upon himself, establishing the tradition of pilgrimage and building the present church on its summit in 1905.

The little church was built by 12 local men on the summit in 1905 using local stone and cement brought up the mountain by donkeys. The building contractor was Walter Heneghan of Louisburgh. It is said around 10,000 people attended the dedication ceremony. On that day, the Midland and Great Western Railway Company scheduled special trains for the ceremony. Peter MacConville’s brass band played at the dedication.

Until 1973 the pilgrimage used to take place at night. Traditionally locals climb Croagh Patrick on the last Friday of July or “Garland Friday”.

In addition, Croagh Patrick has reputedly been a site of pagan pilgrimage since 3000 BC, linking the “holiness” of Croagh Patrick to Pagan traditions. The festival of Lughnasa in honour of Lugh (an ancient pagan god of the Tuatha De Dann) was turned into the Domhnach na Cruaiche or Reek Sunday according to new Christian beliefs.

A recent archaeological survey uncovered an impressive range of ancient sites on the summit and around the mountain including, fulachta fiadh (Neolithic cooking sites), megalithic tombs, standing stones, ring forts, stone ramparts and dwellings. Some amber, blue and black beads dating back to the 3rd century BC were found. More than 30 hut sites and the foundations of an early Christian oratory were discovered on the mountain slopes.

Tírechán, a 7th-century Irish bishop from the Killala Bay area, was also one of the most “widely travelled” of early medieval writers. In his writings, he promoted the cult of Patrick and provided the earliest known reference to Croagh Patrick.

Archaeologists discovered an early Christian oratory dating back sometime between 400 and 900 AD.

The Irish Annals for the year 1113 gives the first reference to Croagh Patrick as a pilgrimage site stating that 30 pilgrims died on the mountain when a terrible thunderstorm struck the summit on the night of the feast of Patrick.

Some years later, in 1185, the medieval Scottish monk Jocelyn recorded that pilgrims used to fast and perform a night vigil on the mountain.

The Black Bell of St Patrick or the “Clog Dubh”, now in the National Museum in Dublin, was a highly revered relic on Croagh Patrick for many years. It was made from iron and dates from 600 to 900 AD. It belonged to the Geraghty family, near Ballinrobe, as Sir William Wilde stated in one of his books (1867). Every year, on Reek Sunday, the family used to bring the bell on the top of the Holy Mountain, where pilgrims were allowed to kiss it for a penny or two pennies if affected by rheumatism pains.

According to tradition, the bell was white but became black because it was used as a weapon against the demons who came to torment St Patrick. This traditional story linked the bell directly to St. Patrick.

Also, Croagh Patrick, along with Caher Island, was a place of worship on an ancient pilgrimage route winding from County Kerry to County Donegal. Another ancient pilgrimage route leads to Croagh Patrick.

It is the Tóchar Phádraig, probably built around 350AD, as the main route from Cruachan (seat of the kings of Connacht) in County Roscommon to Cruachan Aigle, the pagan name for Croagh Patrick.
