St Flannan's Cathedral
About
The Church of Ireland cathedral on Royal Parade, on the Clare bank beside the canal. The cathedral's own history says Donal Mór O'Brien built a church here early in the twelfth century and that it was replaced between 1195 and 1225 by the present building, dedicated to St Flannan. It is built of yellow and purple sandstone and sits on the line between Romanesque and Gothic: the east window is eleven metres high and set in three carved stone arches. Three things inside are worth the visit on their own. The twelfth-century Romanesque doorway in the south wall, which the cathedral says carries over 130 patterns of plants and animals and may come from the earlier church. The Thorgrim stone, found in 1916, which is inscribed in both ogham and Norse runes; the runes read "Thorgrimr carved this cross", and it is dated to about 1000 AD. And a twelfth-century high cross that Bishop Mant brought from Kilfenora in 1821. In the graveyard stands St Flannan's Oratory, a small stone-roofed church that predates the cathedral. The cathedral says it is open daily and services are held on Sundays at 11.30.
