This site at Lismullin 1 was excavated by Archaeological Consultancy Services Ltd (ACS) as part of the M3 Clonee–North of Kells Motorway Scheme on behalf of Meath County Council NRDO and the NRA. The excavation was carried out between 25 January and 13 December 2007 under Ministerial Direction Number A008/0021 and A042 issued by DoEHLG in consultation with the NMI. The museum registration number was E3074. Excavations revealed extensive evidence for prehistoric ritual and ceremonial activity dating from at least the Early Neolithic period until the Early Iron Age. The origins of the site may however stretch back as far as the Early Mesolithic period. Ritual activity in the early prehistoric period was concerned with burial ritual and the deposition of ceramic and lithic material in usually but not exclusively small pits. This activity was episodic in nature. The culmination of these ritual events was the construction of a post-built ceremonial enclosure dating to the Early Iron Age. This enclosure was perhaps built as a physical representation of the sun and the activities undertaken within were enacted perhaps in a period of climate change to effect a positive influence over the agricultural cycle for the local community. The character and longevity of the prehistoric activity indicates that the site should be considered as a developed ritual complex. The character of the site began to change in the later Iron Age when a series of cereal-drying kilns began to be built and used at Lismullin 1 and appear to have been associated with an extensive residential enclosure. In the early medieval period further cereal-drying kilns were constructed and an impressive souterrain was built. This activity suggests the presence of an open settlement in the vicinity of the site. However, no evidence for the existence of habitation structures dating to this period was recorded in the course of the excavations. The evidence from the excavations suggests that agricultural activity was undertaken at the site and its environs between the later medieval and early modern periods.
