This is the most important of these ancient sites, but it is now, unfortunately, nearly levelled to the ground.

This rath is oval and measures about 853 feet from north to south; it contains the ruins of the _Forradh_ and of _Teach Cormac_ (the House of Cormac).

A pillar-stone was removed in 1798 to the centre of the mound of the Forradh.

It formerly stood by the side of a small mound lying within the enclosure of Rath-Riogh.

This stone Dr.Petrie considers identical[175] with the famous _Lia Fail_, or Stone of Destiny, which other authorities suppose to have been removed to Scotland, and subsequently to Westminster.
