Gallow Hillock is a grassy mound situated on top of Backlass Hill (110m OD); only one large boulder remains at the foot of SE slope. It is now much spread and appears to be roughly circular, measuring some 24m in diameter and 1.7m in height, but RCAHMS description suggests that it may be a long cairn.
