Yarngallows Knowe sits in the upper reaches of Glen Afton just short of 5 miles up the Afton Road from the villlage of New Cumnock.
Unfortunately the entry for Yarngallows Knowe in the Ayrshire Ordnance Survey Name Book (1855-57) reveals little about the intrugingly name knowe other than its location –
A Knowe at the southern end of Craigdarroch Rig
The gallows and Scots knowe ‘hillock’  elements of the name are clearly a reference to a gallows hill where condemned criminals were hanged. There was also a Gallows Knowe at the Hall of Auchincross  and at Gallowhill out the Mansfield Road .
The gallows were typically established near a road-side such that the hanging corpses could easily be seen in order to serve as a detterent to both locals and travellers. The ‘Afton Road‘ was one of the key routes between Ayrshire and Galloway.
Gallows were reserved for condemned men while condemned women were drowned in pools or pits of water. It is worth noting that less than a mile away from Yarngallows Knowe to the north east, in a little field between Afton Road and Afton Water is the Witch Knowe and Witch Pool . It may have served a dual purpose and it was here women were tried , on the Knowe, and those found guilty, drowned in the pool.
The element yarn in Yarngallows Knowe remains the difficult element to unravel. Thoughts immediatley turn to twisting a collection of yarns into a rope, but perhaps not to the strength serve the purpose of the hangman’s rope.
Michael Ansell in his place-name articles in New Cumnock News noted that  –
… Yarngallows, a place-name that is very similar to Irongallows in Carsphairn parish. The possibility that the latter contained Gaelic earran, a land portion was considered and discounted by Gilbert Markus in the Place-Names of the Galloway Glens  and he considers this is a Scots Standard English term involving an iron gallows. The Carsphairn example is close to a rock called Craigcrocket possibly Creag Crochadair, hangman’s rock, so this providess circumstantial support for the gallows idea. Was there a similar feature near Yarngallows in Glen Afton.
Perhaps, Witch Knowe & Witch Pool can be claimed as the similar feature near Yarngallows!
If yarn is corruption of iron could this be a reference to corpses hanging in an iron gibbet as opposed to part of, or all of the gallows being constructed of iron?
Thankfully Irongallows is not derived from the demise of some boastful Afton alchemist as was the case in late 16th century Stuttgart. Herre an alchemist and goldsmith by the name Honauer entered the service of Duke Friedrich of Wittenburg and claimed he could convert iron to gold. The delighted Duke, at great expense, arranged for iron to be transported from his armory some distance away. However, Honauer took cold feet and scarpered only to be caught and brought back to the demented Duke who had planned an elaborate execution for the boastful alchemist. A gilded gallows made from 36 hundredweight of iron, the amount Honaeur had promised to turn to gold, was erected and Honaeur was led (not lead!) to the scaffold covered head to toe in gold tinsel and hanged!
