Prestonbury Common Tor

Prestonbury Castle, Preston Berry

A small outcrop can be seen on the precipitous southern slopes of Prestonbury Common high above and to the east of Fingle Bridge. The scattering of outcrops here like others in the vicinity are clearly not of granite and are known locally as 'bad rock' and further extend downhill towards the river.

The 'Geology of the Country around OKEHAMPTON (1968)' by the Institute of Geological Sciences provides further information on page 81, where it is called 'Prestonbury Castle' and described as; "Scattered small crags of hornfelsed, striped and banded, mudstone, siltstone and sandstone in varying proportions..."
