This large stone trough, almost at ground level, is shaped like a large tank / basin and is often about half full of water. The actual spring issues from the nearby bank and flows along a pipe to the trough. On the other end an opening allowing for overflowing water. Today, the well is largerly forgotten, but despite that it is in a resonable state of repair. It appears to have been used as a horse or cattle trough.
It is probably Medieval in date, but the possible dedication to St Helen could make it earlier in date. The well is mentioned by Mr Guy Ragland Philips of Brigantia (1976). The original dedication to the saint in still uncertain, however.
