Hi lordmagic,It seems that we read the same books
As a by note to the info on Waltons spire, it may well be a boundary marker. Because Marsden as in little and great Marsden could be derived from either Marshdene neaning obviously 'marshy valley', or more likely from Merclesdene (sp?) meaning ' marker or boundry stone'.
Also there is no evidence of Roman occupation in the Pendle area, although as you say a track runs down by Castercliff, it then runs through the greenfield area and down by what is now the Pendle heritage centre at Parkhill Barrowford. Although if you look at an aerial photo of Castercliffe just to the left side of the actual fort there is a definate oblong shape which looks like it could have been a Roman marching camp used temporarily by a body of troops. It is interesting to note that the roman historian Tacitus mentions that the Brigantes (our local celt tribe) were the last people to succumb to Roman rule, under the governer Agricola. He further mentions that the tribe would pay tribute as required, but if anyone ridiculed or upset them they would be deadly.
I hope this topic can carry on for a while, as our area is steeped in history.
