Note 18 — THE BRIDAL OF TRIERMAIN. A LEGEND OF THE VALE OF ST. JOHN.
Reading edition
A circular entrenchment, about half a mile from Penrith, is thus popularly termed. The circle within the ditch is about one hundred and sixty paces in circumference, with openings, or approaches, directly opposite to each other. As the ditch is on the inner side, it could not be intended for the purpose of defence, and it has been reasonably conjectured, that the enclosure was designed for the solemn exercise of feats of chivalry; and the embankment around for the convenience of the spectators.
