Just to the left of the modern road and,in shot,directly above the reddish - brown weed,can be seen,on the horizon,a level,straight line with a v-shaped gap in the middle.That is the northern gateway of a Roman fortlet,guarding the summit of the Roman Road over the Stainmore Pass.The fortlet is known by the name of "Maiden Castle".The Romans were the first people to make a road over the pass and the modern road still largely follows the same route today.
