Oct 2007: here some detailed researched on the confusion over Rath Lugh by John Farrelly Posted here
Rath Lugh is a promontory fort over looking the Gabhra Valley, a man made addition to an esker of earth and gravel now covered in trees, a part of defensive zone around Tara. The land originally belond to coillte (the Irish state forestry company) and was given to the NRA who began clearing the trees and digging into the mound in February 2007. In August while focus in the media was on Lismullin workers excavated further into the corpse on Rath Lugh.
As far as I know no (new) archaelogical survey has been carried out on Rath Lugh as the fort itself is not inside the road take. The above aerial photos(*) shows the rath marked in the trees but I have not seen a precise position of the rath but NRA said it wouldn't be affected.. here
Rath Lugh is today separated from Tara by the existing N3 and lies under dense vegetation and tree cover. It was not possible to route the M3 to the east of the site, instead it skirts the base of the elevated promontory on which Rath Lugh is located, approximately 20m below, and will not interfere with the site itself or the view of this site from Tara.Then the NRA said that the line of the fence (photo) was as far as the work would go. And the chief archeaologist Mary Deevy said that excavations were at a part of an esker ridge - two fields away from Rath Lugh". A campaigner Terry tried to drag information out of the NRA who said a retaining wall would be built to prevent further damage of the esker, now maybe the rath itself is not directly affected but the rath's purpose was it's setting which now has been damaged. as DR Conor Newman consultant archaeologist explains.

Rath Lugh circled in fig 3 of this pdf By my eye its 75metres away from the road on that map, and the M3 is describe by the NRA as 20 metres below the fort.
