Grianán of Ailech
It has been proposed that the Cenél nEógain occupied the site of Grianán fort, which may have been within Cenél Conaill territory, and as new kings of the over-kingdom, renamed it after their home territory, giving it its present-day name of the Grianán of Ailech. It is usually identified, whether correctly or not, as the capital of the Cenél nEógain from the 6th century, until its destruction in 1101 by Muirchertach Ua Briain, king of Munster.
