The Mound of Hostages in Ireland is a ancient burial site famous as the capital of the High Kings of Ireland and a holy site for thousands of years. Originally named Temair after a Princess Tea married an Irish King, she brought with her as a gift to the King the Tiatha de Danann's legendary Stone of Destiny, the Lia-Fail.
Much spiritual power and strength dwells in this stone and it is on this that the King would sit at his coronation. If he is the rightful heir the stone would roar beneath him. It was removed from Tara by Prince Fergus and taken to Iona and from there the Scottish King Kenneth MacAlpine carried it off to Scone. But this was not the end of it's travels; Edward the first then had it carried to Westminster Abbey in 1296 and had it built into the throne used for English coronations. It has since been returned to Scone.
Back to the site... near the centre of the main part of the mound is the Fort of Kings and on top of the high mound stands a stone that although is called the Lai-Fail is not the original gift from the Tuatha de Dananns.
