A roughly 1.3km stretch of embankment on the western side of Collister Pill Reen: thought to be an early feature in the landscape - it is followed by early estate/parish boundary (Rippon 1996 'the Gwent Levels', 60ff), the irregular course of this feature suggests that it is not a primary landscape feature.
