Ballygroll Prehistoric Landscape is an 11-acre site in the townland of Ballygroll, County Londonderry [1]. It is a Scheduled Monument and a Monument in State Care [1]. The range and extent of the monuments is remarkable ranging in age from the Neolithic Period until the Late Bronze Age [1]. Most of the monuments on the site have not been fully excavated but it includes several cairns, alignments, standing stones, three different types of grave, a barrow, and a field wall system [1]. The area around the south and west flanks of Loughermore Mountain was first recorded as being an area with a significant number of ancient monuments in Ordnance Survey memoirs in 1835 [1]. However, many of these monuments have been damaged or destroyed [1].
