History and archaeology
The moat of Rathvilly was the residence of Crimthann mac Énnai, an Uí Cheinnselaig King of Leinster, who reigned c. 443–483 and was baptised by Saint Patrick. The placename means "ringfort of the sacred tree"; a bile was sacred to a certain family or ancestral group, and destroying an enemy clan's bile was a common act of war.
