killaloe cathedral and churches

The cathedral was founded about 1185 by Donal More O'Brien on the site of an earlier Romanesque church, the doorway of which is preserved in the south-west corner of the Cathedral. The Cathedral is in the form of a cross, and has three narrow lancet windows in the east gable. Beside the Romanesque door near the main entrance is one of the few stones in the country with a Viking runic inscription; it is unique in that it also has the same inscription in Ogham asking for a prayer for Thorgrim who made the stone. Beside it is the cross removed from Kilfenora by Bishop Mant in 1821, having a figure of Christ, interlacings and geometrical ornaments on it.
St. Flannan's Oratory: In the grounds of the Cathedral is St. Flannan's oratory, otherwise known as 'Brian Boru's vault', which is a 12th century Romanesque church which has lost its chancel but has retained a good Romanesque doorway and a well-preserved stone roof supported by the walls of a small loft above the vault.
