IX.—An Account of remarkable Subterranean Chambers at Trelowarren, the Seat of Sir R. R. Vyvyan, Bart., in the County of Cornwall

Extract

On the beautiful domain of Trelowarren there are, in good preservation, very remarkable subterranean chambers, which appear to have been unknown to Dr. Borlase, the county antiquary, and are mentioned by one only of the Cornish historians, Polwhele. Polwhele's description, however, being unaccompanied by plans or accurate measurements, is of little use to the archæologist, and no more may be gathered from his remarks than that those galleries were not in his day, about fifty years ago, so easily to be investigated as at the present time.
