The fort was – is? known by another name:
We remember passing a day pleasantly enough in tracing one of the last-mentioned relics of olden time, midway between Blandford and Dorchester, which the people to this day call Castle Rings. Our stay would not allow us much research; but we finished our excursion by starting from Milborne, on foot, across the fine expanse of Dorset, the bold ridges of Southampton, where the artificial luxury of a stage-coach put an end to all our enjoyment of romantic nature.
