At the distance of about 490 yards eastward of the centre of the Camp is a copious and ever-flowing spring of pure water, called Holy Well, which rises from the side of a steep mount near a lone farm house, and flows, in a stream which would be sufficient to turn two or three overshot wheels, down a dell to Lower Tadmarton village. There existed, not many years ago, remains of a paved way made from broad flags, leading to this spring from the camp or the outwork near the entrance.
