King Doniert’s Stone / Menkov Donyerth Ruw is the base for a Celtic memorial cross that dates to the late 9th century. It is thought to commemorate King Doniert (Durngarth), the last recorded King of Cornwall. There is a mortice hole cut into the top of the stone which is where the cross would have been fitted. An interlace pattern is carved on three sides of the stone and on the fourth is an inscription in Latin,
“Doniert rogavit pro anima”
which translates as “Doniert has begged for prayers for his soul”
Next to the base stone is another Celtic decorated base known as ‘The Other Half Stone’ which was also meant to support a granite cross. The front is decorated with an eight-cord plait, the two sides are plain so it is not known if this was ever finished.
These stones stand at the side of the road across the moors to Minions village, close to the turn off to Siblyback Lake. The stones and land on which they stand was given to the nation by G P N Glencross, M A Rundle and L S Lang. The site was enclosed and laid out at the cost of the Liskeard Old Cornwall Society.
