 In 1816 the landowner, Mr R Hunter, reported that there were the appearances of an arch in the centre of the Castle Knowe that was orientated North to South.The remains of a drystone dyke in 2016 ran across the eastern side of the knowe and ran down to join the maintained dyke at the main road whilst in 1855 a drystone dyke ran across the end of the knowe on the western side.The source of the stone used for these dykes is not recorded.
