Lympne in the context of Boxing the compass

Watling Street is a historic route in England, running from Dover and London in the southeast, via St Albans to Wroxeter. The road crosses the River Thames at London and was used in Classical Antiquity, Late Antiquity, and throughout the Middle Ages. It was used by the ancient Britons and paved as one of the main Roman roads in Britannia (Roman-governed Great Britain during the Roman Empire). The line of the road was later the southwestern border of the Danelaw with Wessex and Mercia, and Watling Street was numbered as one of the major highways of medieval England.

First used by the ancient Britons, mainly between the areas of modern Canterbury and St Albans using a natural ford near Westminster, the road was later paved by the Romans. It connected the ports of Dubris (Dover), Rutupiae (Richborough Castle), Lemanis (Lympne), and Regulbium (Reculver) in Kent to the Roman bridge over the Thames at Londinium (London). The route continued northwest through Verulamium (St Albans) on its way to Viroconium Cornoviorum (Wroxeter). Watling Street is traditionally cited as having been the location of the Romans' defeat of Boudica, though precisely where on the route is disputed.

Portus Lemanis, also known as Lemanae, was the Latin name of a Roman Saxon Shore fort, settlement and port in southern Kent. The modern village of Lympne derives its name from the ancient port. The site, known locally as Stutfall Castle, is on private land which is accessible by public footpath.
