Extract from William R. Wilde’s Loch Coirib

Eanach Dúin, the dun or “fortress of the bog”–and in modern Irish Eanach Cuan, “the harbour of the bog,” or possibly of St. Cuana–giving name to a large parish in the barony of Clár, about 12 miles from Galway, is the first stopping place of the steamer, and contains the chief group of ruins that occur on the eastern shore of Loch Coirib, on our upward route. They consist of a picturesque tall square castle, still in fine preservation, the walls of the Bishop’s residence, with the wells of St. Brendan, the founder, and St. Cormac, on the south; and the extensive remains of an Abbey and Monastery, and also a Nunnery, and other ecclesiastical buildings, on the north side of a rocky inlet of the lake, into which a small stream pours its waters. In early Christian times this was the site of the fifth Bishop’s See in Connacht, the boundary of which was co-extensive with the seigniority of Iar-Chonnacht, and in the territory of the chiefs of Ui Briúin Seóla, the progenitors of the O’Flahertys, ere they were driven by the De Burgos and other English settlers westward, across the lake, into the baronies of Moycullen and Ross.


St. Brendan, having established a nunnery, and placed his sister Briga, a canoness of the Augustinian Order, over it, died here, but was interred at Cluain Fearta, A.D. 577. Several of its bishops are mentioned in the Irish Annals; but the episcopal lords of the neighbouring diocese of St. Iarlaith, and especially Archbishop Mac Aodha, feeling perhaps some jealousy on the subject, induced Pope John XXII in 1321 to issue a bull to suppress it, and join it to that of Tuaim; and many of its revenues and valuables were transferred to the collegiate church of St. Nicholas in Galway. The mandate of the Pontiff does not, however, appear to have been implicitly obeyed either by the Irish or English; for some of its bishops are enumerated after that date; and, so late as 1484, Richard III “dispatched to Ireland Thomas Barrett, a cleric of Somerset, who had been appointed to the bishopric of Enagh-dun, in Connacht, to instruct the Deputy Kildare by all possible means to bring into the King’s power the Earldom of Ulster, then almost entirely possessed by the native Irish.” And in order to conciliate the Desmond of the day, the Bishop brought a royal message that he should “renounce the waringe and usage of the Irish array;” and presented him with the King’s livery, consisting of a collar of gold weighing twenty ounces; and from the King’s wardrobe a long gown of cloth of gold lined with satin, doublets of velvet and crimson satin; stomachers, shirts, and kerchiefs; hose of scarlet, violet and black colours; bonnets, hats, and tippets of velvet, etc. But, gorgeous and enticing as this English “array” was, it will not bear comparison with that of Cormac Mac Airt many centuries before, as related in the “Book of Ballymote;” nor of O’Donnell, respecting whose costume the Lord Deputy St. Leger, when that Irish chieftain requested “Parliament robes,” informed the King that–“At such time as he mette with me he was in a cote of crymoisin velvet, with eggletts of gold, xx or xxx payer. Over that a greate doble cote of right crymoisin satin, garded with black velvet; a bonnet, with a fether set full of eggletts of gold, etc.”

Eventually, the bishopric of Eanach Dúin was incorporated with that of Tuaim; but it does not appear, from the histories, to have been given up without a struggle; and the adjoining castle, which is probably of De Burgo origin, was significantly placed on the south shore of the little creek between the residence of the diocesan and his cathedral: while, at the same time, it commanded an extensive view of the country of the O’Flahertys towards the west. When the Monastery of Eanach Dúin was suppressed, it was granted to Richard Earl of Clanricarde.


The present Church.

On Sunday last the ceremony of dedicating the new church at Annadown was carried out with great stateliness and pomp…

– Tuam Herald, 18 July 1903

The construction of Annaghdown Church (St Brendan’s Church by the Lake) was commenced in early 1900 and the dedication was performed by Most Rev. Dr John Healy, Archbishop of Tuam, in July 1903. It was built by a Mr Nee of Roundstone, and designed by a Mr Hamilton, architect, of Galway. Extensive fundraising took place both locally and amongst Galway natives in the United States.

The church was almost completely destroyed by fire on the night of 1 December 1936, following which it was restored and extended.
