Medieval sources describe them as the ceremonial capitals of various Irish kingdoms, where kingly inaugurations, assemblies and athletic games were held.
Archaeological investigations show that many royal sites were culturally significant for thousands of years before recorded history, and they often include ancient monuments such as Neolithic burial mounds, standing stones, cairns and enclosures.
[6] Herity also notes that a composite mound and circular enclosure structure, exemplified by the combination of An Forradh and Teach Cormaic, is almost exclusively found on royal sites.
[9] This accounts has been criticised as propaganda designed to make the Irish look barbarous or pagan but would be consistent with an Indo-European tradition of inaugural horse slaughter.
[11] An account of the Choncobhair ceremony records the would-be king leaving a single slipper at his inauguration site to signify his claim.
[13] Cartographer Richard Bartlett drew the chair at Tulach Óg the inauguration site of the Ui Neill of Tir Eoghain.
The only extant Irish inauguration chair, now in the Ulster Museum, belonged to the Ui Neill dynasty of the Clann Aeda Buide.
