 One of these roads may have been Wade's Causeway, a possible Roman road, which led north-eastwards over the Vale of Pickering and across Wheeldale Moor towards the North Sea coast.There are Roman camps at Cawthorn and Lease Rigg near Grosmont and there are signal stations along the coast at Filey, Scarborough, Ravenscar, Goldsborough and Hunt Cliff.The Romans left Britain in AD 410.
