Lying south of the old site of Peelbraehope, now almost lost to the forest and entirely off the beaten track, the Tinlee Stone is a standing stone about four feet tall, three feet broad at the base, tapering toward the top. It has been historically used as a boundary marker, but its original purpose and origin remain unclear. It may well be significant that it stands close to a section of the Catrail. It is possible that the Tinlee Stone was once used as a meeting point by the Wardens of the Marches during the reiving years, perhaps a point of truce, at which the Wardens could peaceably discuss and resolve interpersonal and familial grievances. Though, whether this was an adopted use for the stone, or its original purpose, is not known.
