The mountain of Knocknarea on the Cuil Irra peninsula west of the modern town of Sligo forms an eye-catching landmark along this stretch of the Sligo coast. The smooth skyline of the mountain is conspicuously interrupted by the huge un-opened passage tomb cairn of Miosgan Meadhbha, the legendary burial place of Queen Maeve.
The Cuil Irra peninsula was a major ritual centre in the 4th millennium BC, and formed together with Bru na Boinne, Loughcrew and Carrowkeel-Keashcorran one of the four large ritual landscapes within the Irish Passage Tomb tradition. The c. 50 remaining passage tombs on the peninsula and in its hinterland bear witness of the intense ritual activity that once existed here.
The Knocknarea Archaeological Project was initiated in the late 1990s and its overarching aim has been to understand the role the mountain would have played in the ritual and secular lives of people in the Neolithic.
The archaeological remains on the mountain belonging to the Neolithic period consist mainly of a series of passage tombs, round house foundations as well as a complex series of banks along the upper eastern slopes. The presence of barrows, enclosures, rectangular house foundations as well as more ephemeral remains indicates that the mountain was continuously used for various purposes all through prehistory and medieval times up to the present day. 
The field element of the project has involved detailed recording of the archaeology on the mountain, but also a series of focused excavations of selected sites over the years.
The completely unexpected discovery of an extensive and complex system of Neolithic banks, measuring some 2.5km in total length, along the eastern slopes forced a complete re-interpretation of the activity on the mountain. Finds from the banks indicated that they had been the focus for large scale lithic production using the locally available chert. The hollow scraper completely dominated the retouched tools, even though a more or less full range of Neolithic artefacts was present.
A series of C14 dates from various contexts along the banks firmly dates them to c. 3350 cal. BC.
Four of the in all c. 15 round house foundations on the mountain have to date been excavated. The finds in these houses correspond to those recorded along the nearby banks and a similar date for the houses can be assumed.
Among the remains from later periods, a group of in all four rectangular house foundations were recorded on a narrow ledge on the steep northern slopes. The top soil was removed at one of the house foundations, to facilitate the production of an plan of the site. No finds where made and the cluster of in all four buildings remain undated. A preliminary date to the late medieval period may however be suggested, based on building techniques and layout.
