I didn't get this place at all......(it's only a short steep climb up Bole Hill of several 100m's from the stones of Strawberry Lea). But most of the remains (well kinda the most sorta visible) up there seem to be related to the old lead smelting workings...
Then again if your'e an hardcore hillfort fan then it's possible I guess you might be able to find something...
"The summit of the hill, between Bole Hill Lodge and the city boundary, an area estimated at 450m by 150m, is contained within the remains of ramparts and ditches." YAJ 51, 1977.
