The following report describes the results of archaeological excavation at that site. The area was fully excavated by Carmel Duffy under Excavation Licence Number 04E0857 issued by the DOEHLG in consultation with the National Museum of Ireland for IAC. The fieldwork took place between the 16 and 23 June 2004. An area c. 30m by 25m was stripped of topsoil to reveal pits and linear ditch-like features in an area of tillage with a gentle hillside rising up to the east and south. The ditch like features formed a small possible enclosure. Two possible entrances were identified and further linear ditches were identified extending away from the enclosure – one at each entrance location. These may have been field boundaries, and it is possible that the main enclosure was also part of a field system. The ditches were not particularly deep, and this suggests that they were not associated with a ringfort or earthwork. Two pits were also identified, both of which were truncated by one of the linear boundary ditches. Radiocarbon dating of a charcoal sample from one of the pits indicates an early medieval date. The site is in close proximity to a souterrain DU020-010 so it is possible that the site is associated with a wider complex of early medieval archaeology that may survive outside the roadtake.

excavation carried out in the townland of Bustyhill, Co. Dublin. It is based on the direct stratigraphic relationships recorded on site and the results of specialist analysis of artefacts and samples from the site. The works formed part of an archaeological mitigation program associated with the N7 Naas Road Widening and Interchanges Scheme, Contract 2; Kill Village to Rathcoole, south Co. Dublin. Archaeological fieldwork was directed by Carmel Duffy of Irish Archaeological Consultancy Ltd. (IAC Ltd.) and was funded by Kildare County Council and the National Roads Authority. 1.1 Site location Site 5, Bustyhill, Co. Dublin was identified during Geophysical testing. Linear and Offset Testing was carried out by Elizabeth Connolly for IAC Ltd (licence 03E1731). It consisted of potential archaeological features as follows: - a curvilinear feature roughly forming a circle, - two linear tangential features, one running westwards, the other eastwards, from the circle. • Site 5, Bustyhill,
