Also known as Siward's Cross, Nun's Cross is one of many granite stone crosses across Dartmoor. The cross sits at the junction of two major tracks; the Abbots’ Way and the Monks’ Path, which link abbeys at Buckfast with Tavistock and Buckland.
The cross stands close to Nun's Cross Farm, which can be seen from the junction.
Although the meaning behind its more common name is unknown, the word Siward is carved into the stone, which is thought to refer to the Saxon Earl Siward, who once was a landowner around Tavistock.
