The large circular mound of an unusual 3-ring fort, not excavated until 2009. It may have been associated with the slightly smaller Rathanadav ring-fort to its south.
Using highly sensitive equipment, the soil was subjected to “high-resolution magnetic imaging” – similar to an MRI scan. It is the first time that any of the fairy forts in the countryside surrounding the Rock of Cashel has been surveyed in this manner.

Speaking to The Irish Times about the results, Mr O’Brien said that “none of the traditional evidence associated with ring forts – such as houses, hearths or rubbish pits – was found”. Instead, the team discovered that the site may have been first used 3,000 years ago during the late Bronze Age.

He said one of the most exciting discoveries
evidence of a Stonehenge-style circle of wooden posts suggestive of “a ceremonial or ritual role for the fort”.

Mr O’Brien said the use of the site would have changed down through the centuries and the survey results indicate that it had “a royal function”.
