Not far from the Visitors’ Centre is Gallowhill. It is thickly wooded and from its vantage point can be enjoyed one of the best views of Craigend Castle situated below. As its name implies, this was the site where felons, cattle thieves, arsonists and murderers were executed by hanging or strangulation.
The last man to die here was Patrick McNicol on 28th March 1718. McNicol and five others had been arrested at Inversnaid on Loch Lomondside whilst attempting to steal cattle belonging to the Duke of Montrose. The accused were taken to Mugdock Castle and held there in the small cell at the base of the south-west tower to await trial. On 6th December 1717,the six prisoners overpowered the jailor’s son and his servant when the pair brought them their supper. As they raced towards the Castle gate, they found their way barred by the jailor himself, John Graham. In the ensuing scuffle, Graham was stabbed several times and later died of his wounds. McNicol, who was stunned during the exchange of blows, lay on the ground nearby his fellow prisoners having escaped under cover of darkness.
The charge against McNicol was now no longer one of cattle-thieving but of murder although no one had witnessed McNicol striking the victim. He was tried by the Court of Justiciary on 13th and 14th March 1718 before a jury composed of 43 men, most of whom were Grahams. The verdict was a foregone conclusion. McNicol was found guilty and executed by hanging at the Gallow Hill on 28th March 1718. The executioner was paid 20 pounds Scots for “turning him off”.
The cache is located at the foot of Gallowhill, and is a little bit off the track, but not too far. Unable to place the cache at the actual tree.
