It [the Fosse Way] runs from Exeter in the south west to Lincoln in the north-east, and was built in the middle of the 1st century AD. The word Fosse comes from the Latin word for ditch (Fossa) and is appropriate for this road as for a long time, the western boundary of Roman controlled Britain was protected by a defensive ditch running between Exeter and Lincoln. Whether the ditch was filled in and the road built later, or whether the road was built to follow the ditch is a subject of much conjecture. What is certain is that the road got its name from the ditch.
