IAC carried out geophysical survey, archaeological testing and assessment as part of an EIA for a proposed residential development 1km west of Drogheda in Rathmullan. The River Boyne flowed 400m to the north of the site and the M1 lies 250m to the west. Geophysical survey identified the remains of an enclosure which was investigated with test trenches by IAC. No visible above ground trace was noted of the enclosure however the ditch appeared substantial in testing. It was recommended that this area be left as undeveloped greenfield or if not possible that the site be fully excavated.

The small road that borders the west of site is likely the route that King William used to travel south with 3500 troops in order to confront King James at Donore. It is possible that artefacts associated with the movement of troops exist under and within the immediate vicinity of the road. It was recommended that a program of further testing and metal detection be carried out to further investigate the potential of the development area.
