Mr Hunter says there is an old story about [the Bridge of Tillypestle] being the scene of a fight between two giants. Mr Hunter says they killed each other and were buried on two hills close by, one on Knapperty Hill, and the other on Cairndale hill, and he says that two cairns were erected to commemorate the affair. The cairn on Knapperty Hill is still to be seen but Cairndale Hill can boast of but slight traces of the cairn that stood on it.
From the Aberdeenshire Ordnance Survey Name Books (1865-71).
Tillypestle Bridge is about half way between Knapperty Hill (the site of Auchmachar cairn and circle) and Cairndale hill. The large cairn on Cairndale Hill “was removed by the farmer at Coilsmore, for the purpose of building dykes on this farm.”
