On an imposing hilltop encircled by trees some 2 miles south/south east of Cookstown and on the outskirts of Tullyhogue village is the site of the mystical Tullaghoge Fort, prominently standing testimony to Tyrone's illustrious past. It was here on this hilltop enclosure that the ruling members of each generation of the Cenel nEogain (later to be known as ‘The O’Neills’) were inaugurated from the 11th Century to the end of the 16th Century. The Uí Néill (O’Neills) founded their headquarters at Tullaghoge early in the 11th century and it continued as the ceremonial seat of the kings of Tír Eoghain even after the O’Neills transferred their court to Dungannon at the end of the 13th century.
