Editor’s Note: The reference below from 1769 may refer to Gunhill Cliff

On the cliff [under South Wold] are two batteries, one of which is a regular fortification, with a good parapet, and six guns that are eighteen pounders. The other has only two guns, which are nine pounders. On this hill, and several others that are near it, are the remains of a camp; and where the ground has not been broken up, there are tokens of circular tents called Fairy-hills, round which they suppose the fairies were wont to dance. “A Description of England and Wales” (London, 1769), vol. viii, p. 282,
