The Ox Eye long cairn has only fairly recently been recognised as such. It was first noted in the early 1990s and was surveyed about ten years later by members of the Border Archaeological Society. The prehistoric cairn is trapezoidal in shape and measures 55m long by 22m wide and stands just over 2m high. The edges of the cairn are quite difficult to see as they have tumbled and are covered in bracken. This is one of only a handful of long cairns in the county.
