Brian Boru’s fort is a large ring fort between the River Shannon and the Killaloe to Tuamgraney road. It has long been identified as the ancient seat of Brian Boru, the most famous High King of Ireland.Brian Boru’s fort is located in a very serene and spectacular setting, overlooking Lough Derg on the River Shannon, just one mile north of the picturesque village of Killaloe. Beal Boru, as it is more commonly known, stands on a spur of land which commands the point where the lake narrows into the River Shannon.
Brian Boru (Bórumha, bóraimhe, meaning a cattle tribute) was either born or reared at this mystical location, according to folklorist Daithi O hOgain, and the placename, Béal Bóramha, means the ‘port of the cattle tribute’. Boru was high-king of Ireland from 1002 until his death in 1014AD.
His headquarters was the nearby Ceann Cora (in English Kincora) which is located one mile from here in the picturesque village of Killaloe. His death came during the battle of Clontarf against the Norsemen, a battle which was to claim Boru’s life, but which he won nonetheless.
