The site was used by the O’Conor kings as an inauguration site. The O ‘Conor’s were the high kings of Connaught and also gave Ireland two of its final high kings Tairrdelbach Ua Conchobair (Turlough O’Conor) Ruaidrí Ua Conchobair (Rory O’Conor).
The current O’Conor line lies with the descendants of Cathal Crobhdearg Ua Conchobair, Rory’s youngest brother and King of Connacht who lived in the Rathcroghan Area. The ‘Conchubhair Donn’, the senior member of the entire Muireadaigh dynasty, likewise descends from Cathal Crobhdearg.
Rory O’Conor was the last ‘High King of Ireland’ and the only ing of Ireland’ to hold this title which was created during his reign before the Norman invasion. It was Rory’s invasion of Leinster which resulted in the exile of its king, Dermot MacMurrough, who invited the Normans to Ireland.
Carnfree is located on high ridge over the village of Tulsk and is marked by a series of Burial Mounds and a standing stone, most likely used during inauguration ceremonies.
