A previously unrecorded “impressively large earthwork” – believed to be part of the outer defences of an early medieval royal stronghold at Knowth, in the Boyne Valley of Ireland – has been identified by an archaeological survey. The survey, commissioned by former attorney general John Rogers SC, has been submitted to An Bord Pleanála as additional information as part of its consideration of plans for an N2 bypass running east of Slane, County Meath.
Carried out by archaeologists Joe Fenwick, Gerard Dowling and Roseanne Schot of the Brú na Bóinne Research Project, the survey found the earthwork at Crewbane, near the home of Mr Rogers, who is objecting to the bypass. It was prompted by the discovery in 2007 of a souterrain in Crewbane, at the perimeter of the Brú na Bóinne Unesco world heritage site “buffer zone” 2km east of Slane village and 1km from the prehistoric passage tomb of Knowth.
