Historically aerial photography, and latterly LiDAR, have been used to identify and map new sites in the Brú na Bóinne World Heritage Site (WHS), an internationally significant archaeological landscape known for its Neolithic passage tombs, other monuments and megalithic art.
Recent analysis of LiDAR data from the Brú na Bóinne WHS undertaken as part of the INSTAR (Irish National Strategic Archaeological Research) Boyne Valley Landscapes Project, which directly addresses a number of the knowledge gaps identified in the Brú na Bóinne WHS Research Framework (Smyth et al. 2009), has revealed a host of new monuments in this important archaeological landscape. This poster presents some of the results of a programme of ground truthing of a small sample of sites: Site W in Monknewtown - a previously recorded monument - and two sites first identified on the LiDAR data (LP1 in Newgrange townland and LP2 in Dowth townland). Ground-truthing involves a combination geophysical survey and coring to obtain material for sedimentological and geochemical analysis and for radiocarbon dating
