Sheep grazing on the earthwork, Dallam Park

The earthwork is 'a medieval ringwork located in Dallam Park on a
prominent hilltop known as Castle Hill 380m south east of Dallam Tower' Link and is a scheduled monument.
'The ringwork includes a sub-circular earth and stone mound measuring up to
42m east-west by 35m north-south. It has a flat top which has been created
by raising the mound above the surrounding landscape only slightly on the
north side but between 2m and 4m elsewhere. The top of the mound measures
27m by 22m and it contains an earth and stone bank up to 0.35m high around
its eastern, southern and western edges.'
As well as the obvious structure on top of the hill the slopes also seem to have lots of parallel ridges and grooves accentuated here by the lowering sun. I wonder if these are agricultural?
