The Rock of Cashel, old seat of the kings of Munster, was granted with the territory around it to the Church in 1101 by King Muirchertach Ua Briain, and Cashel became an archiepiscopal see, its primacy over Munster confirmed at Kells in 1152.
Its archbishop is lord of the Rock and of the town below it. In 1200 Cashel stands in a Munster torn between the O'Brien kings and the English barons pushing into Tipperary, and its archbishop is a Cistercian and former papal legate, Innocent's kind of bishop.

Wealth
Church rents; the prestige of the Rock as Munster's royal and sacred centre.
Threats
- English expansion in Tipperary
- Dynastic war among the O'Briens
Advocates and rivals
The O'Brien kings of Thomond; the English barons granted Tipperary lands by John, among them Theobald Walter (Hubert Walter's brother), Philip of Worcester and William de Burgh.
Places of note
- Rock of Cashel: Cormac's Chapel and the cathedral on the Rock
Where the sources disagree
Evidence: The 1101 grant and the buildings are well known; the archbishop's lordship over the town in 1200 is thin (the town's first charter from an archbishop comes later). The archbishop's page could not be read.
On the map: The extent of the 1101 grant is not traced; the district round the town stands for it.
