Identification

Category: Plausible. It has been suggested this could be the remains of a field boundary. Historic field boundaries in the vicinity consist of banks and ditches and are not formed by stones.  This line of stones leads from a stone circle towards a cairn. The existing evidence strongly supports a prehistoric interpretation.

Row of small stones leading towards the smaller of the two stone circles. View from west (Scale 1m).

Looking south west along the row (Scale 1m). This row is aligned on a cairn 172m from the eastern end of the row. Deep peat and small stones means that it is possible that this row once extended as far as the cairn.

Looking along the row from the south west (Scale 1m). Whilst much shorter, this row is very similar in character to the row at Bancbryn.

The stone row may extend as far as the cairn at SN 83140 30992. Deep peat deposits may have accumulated over the small stones. If this is the case the row would be 172m long and lead between a cairn and a stone circle.

Access Information

Car parking is available at SN 84525 30024. From its a bit of a hike along the track leading west. After about 1.5km head north across open moorland to the row and stone circles. Don’t forget to visit the cairn at SN 83140 30992.
