Little remains now of this once important ecclesiastical site. It was allegedly founded in 548 by St. Fintan. Nothing remains of the original structure which was destroyed in 838 by the Vikings. The site was plundered again in 937 by the King of Cashel and the Danes of Waterford. A holy well, now destroyed, was associated with the site as is the holy tree located here. Before the tree collapsed some years ago, the water that collected in the trunk was thought to have healing properties. The tree collapsed due to severe metal poisoning. It was traditional to hammer coins into the tree as a votive offering. Fortunately, new branches have started to grow from the remaining stump, but the coins still persist. It is advised that you don’t hammer coins into the tree and pull out any that you can.
