Baronies were created after the Norman invasion of Ireland as divisions of counties and were used the administration of justice and the raising of revenue. While baronies continue to be officially defined units, they have been administratively obsolete since 1898. However, they continue to be used in land registration and in specification, such as in planning permissions. In many cases, a barony corresponds to an earlier Gaelic túath which had submitted to the Crown.
The barony of Tulla Upper lies in the northeast of County Clare. It is bounded on the northwest, north and northeast by County Galway, on the east by county Galway and the barony of Tulla Lower, on the south-east and the south by the barony of Tulla Lower, and on the south-west and the west by the barony of Bunratty Upper.
The barony covers 96,730 acres (39,150 ha) of which 2,911 acres (1,178 ha) are water. The land is mostly moorish upland, with peaks rising to 1,312 feet (400 m) in the north. It includes the Scarriff bay of Lough Derg, and loughs O’Grady, Bridget, Anilloon, Kilgory, Culausheeda, Ea, and Graney.
Parishes and settlements
Until 1898 the parishes of Clonrush and most of Inishcaltra were in the barony of Leitrim in County Galway. That year they were transferred to Tulla Upper and County Clare. The barony contains the parishes of Clonrush, Feakle, Kilnoe, Moynoe, Tomgraney and Tulla and Inishcaltra. The main villages are Scarriff, Tulla, Tomgraney, Feakle and Baurroe.
