Rampart and ditch upstanding.<1> The northward extension of Lexden Dyke (site 11628) north of the River Colne. It originally curved round between Black Brook and Salary Brook as is indicated by the name `The Rampers' given to this stretch in a C17 perambulation of the Borough.<2> Assigned to a phase of construction that took place around the time of Cunobelin's succession in AD 10.<2><3>

Site Assessment = This dyke still exists for most of its length because it runs through open countryside. It appears to be used as a boundary between the land either side of it and is wooded over in parts. Although the railway line cuts through its northern tip and it tends to fade as it runs towards the by-pass it is still in a reasonably good state of preservation.<4>
