What is recorded here

Ring-ditch in Blennerville is a vanished circular enclosure hidden beneath marshy land near the River Lee flood plain. Infra-red photography reveals a dark thirty-metre line where no ground trace remains, suggesting people shaped that wet valley long before modern memory. The ditch may have marked a home, a boundary or a ritual place, yet the marsh swallowed every stone and post until light itself stopped recording the change.

'Infra-red aerial photography (National Coastline Survey) clearly shows a circular cropmark enclosure at this location in an area of marshy land close to the flood plain of the River Lee. The site shows clearly as a dark line and is approximately 30m in diameter. There is no trace of the site at ground level.' Description from ‘The Prehistoric Settlement of the Lee Valley, Tralee, Co.
