Quarrying operations at one time threatened to destroy this far-famed natural curiosity, but the Duchy of Cornwall has wisely limited the scope of their destructive efforts. [...] Immediately outside the rampart of the stone fort above the Cheesewring is a large natural block of granite, hollowed out by the weather into a rude seat called the Druid’s Chair. It is said that whoever sits in it is destined shortly either to become a poet or go mad – in fact, the Laureateship or Colney Hatch!
From a report about an excursion to the Cheesewring in Archaeologia Cambrensis, July 1896.
