This lovely granite stone sits beside the B2588 heading west out of Penrith. It’s a good sized stone. There are other possible fallen or cleared stones on the other side of the field wall.
In his ‘Carnac to Callanish’ book Burl mentions “vestigial lines of standing stones” at Newton Reigny. The village is only about 1km to the north west making this stone a possible survivor of one of those rows.
