Saint Flannan's Cathedral, Killaloe, Clare

Killaloe in County Clare is a village lying on the River Shannon. It is historically associated with Brian Boru, Ireland's only High King who could rightly lay claim to dominion throughout Ireland.
Brian died victorious at the Battle of Clontarf in 1014.... A Pyrrhic victory.

Saint Flannan's Cathedral is a hidden jewel located just 100 metres or so from the bridge which leads across the Shannon from Ballina (not Mayo Ballina) and into the village.

Thorgrimr stone

The Cathedral was originally built in the late 12th century and was substantially altered and added to over the intervening years.


The building itself is architecturally beautiful on the exterior and holds a few hidden gems inside which are fascinating in and of themselves.

There is a Romanesque Doorway inside the Cathedral which dates from the late 1190's and is covered in Chevrons, Zigzags, and a host of intricate plant and animal designs. Two grave slabs inserted into the floor directly beneath it are said to mark the burial place of Muircheartach O'Brien, a King of Munster.

Also located in the Cathedral is Thorgrimr's Stone. This is the only known example in Ireland of a stone containing both Scandinavian Runic and Irish Ogham Script.
Ogham is a 20 letter Old Irish alphabet also known as "the tree alphabet."

A beautifully designed baptismal font is to be found inside the Cathedral and dates from the 13th Century. Dividing the Cathedral interior is a huge Oak screen dating from 1885 which can be opened up if need be to make extra room inside.

Killaloe is named after Saint Lua (Molua) Cill da Lua i.e. the Church of Lua.

Saint Flannan's in Killaloe

A Church was founded by Molua on Friar's Island on the Shannon sometime in the 6th Century. This island was flooded over when a hydroelectric plant was established at Ardnachrusha downstream on the Shannon.

Lua's Oratory

In 1930 the small 7th Century Church ruin and Oratory of Lua were disassembled on Friar's island brick by brick and moved upstream by barge to be re-erected on the grounds of Saint Flannan's Roman Catholic Church which is a short walk from the Cathedral. This structure is variously referred to as Saint Molua's Church and Saint Lua's Oratory.

A couple of miles outside and upstream from Killaloe is Brian Boru's Fort, a  large earth ringed enclosure which was originally an Irish Ring Fort and later an Anglo Norman fortification. The area is very scenic, worth dropping in if passing.
