An 11-acre Scheduled Monument in the townland of Ballygroll, County Londonderry, Northern Ireland, preserving a remarkable concentration of monuments spanning the Neolithic to Late Bronze Age. Features include a court tomb with a cup-marked capstone, several wedge tombs, two stone circles, cairns, and extensive stone field walls. Archaeological excavations in 1978-1979 investigated a barrow and field walls. The preserved area represents only a fraction of the broader prehistoric landscape on Loughermore Mountain, much of which was lost to agricultural development since the 1830s.
