 Auchenharvie has long been a ruin, shown as such as far back as 1604 - 08 by Timothy Pont.It was too small and the area of the mound also so restricted that its conversion into a more commodious and comfortable dwelling was not practicable.The corbels of the parapet are unusual in that they project less than usual and this links Auchenharvie with the work at Law Castle and Barr Castle.
