Clonfert Cathedral
In the flat country by the Shannon, a few kilometres from Eyrecourt, a small sandstone church holds the greatest Romanesque doorway in Ireland. Clonfert was St Brendan the Navigator's monastery, founded in 563 and his burial place; the church that stands is of about 1180, and its west door, six orders deep and crowded with heads, is the crowning work of the Hiberno-Romanesque style.

Brendan's monastery
The annals put the founding of Cluain Fearta Brénainn in 561, on the day of the battle of Cúl Dreimne, at the order of an angel; they record its bishops and abbots from Maenu in 572 and Senach Garb in 621 onward, and a burning in 749. It became the cathedral of the Diocese of Clonfert, then one of three cathedrals of Limerick and Killaloe, and is now one of five in the united Diocese of Tuam, Limerick and Killaloe of the Church of Ireland; its dean, Roderick Lindsay Smyth, is dean of Killaloe and Kilfenora and dean and provost of Kilmacduagh as well.
The doorway and the mermaid
The earliest part of the church dates to around 1180, and the doorway is its glory: six orders of carving, animal heads, foliage, human heads, under a pointed hood filled with triangles alternating with strange faces, and beneath it an arcade of more heads. The east windows of the chancel, early thirteenth century, are late Romanesque; the chancel arch, put in during the fifteenth century, carries angels, a rosette and a mermaid holding a mirror, worn smooth by centuries of hands. The arches under the west tower carry fifteenth-century heads too.
Saving the stone
The soft sandstone has weathered badly, earlier conservation did not solve every problem, and plant growth made it worse; with a small congregation and few resources, the cathedral was placed on the World Monuments Watch in 2000, and American Express gave money through the fund for its care. The church stands in Clonfert village in the parish of Eyrecourt, with the Shannon and Meelick's church of 1414 nearby; the model on this page pins them.
