The Romans brought roads to Britain including one from Londinium to Durovernum (London to Canterbury). This was later named Watling Street. It was a principal road during their rule. A map of Watling Street In 1897, the paved surface of the old Roman road was found towards the base of East Hill below the present roadway. It was constructed from large round pebbles set on end. Roman stone coffins were discovered on East Hill in 1792 and 1882. In 2006 excavation of a Roman cemetery uncovered further remains but also prehistoric archeological evidence.
