More information : Centred at NZ 1219 2496 around a disused 18th/19th century coal shaft, and on both sides of the old trackway, are six enigmatic earthworks of similar form, overgrown with turf and bracken. They were surveyed at 1:500 and 1:1000 in 1984 by RCHME (marked 14 on RCHME 1:1000 plan).
The earthworks take the form of rectangular or square enclosures bounded by an earthen bank, up to 0.6 m internal height, on all sides except the north which is open. The one exception to this rule, which appears to overlay the parallel banks of what may have been a hollow-way, has its open side is to the south towards the old shaft. They are all roughly the same size, varying from 7.0m-9.0m internally by approximately 6.0m-8.0m transversely, the longer axis being generally E-W. All are distinguished by containing within them from one to five parallel earthen banks up to 0.4 m high; they resemble combs in planform.
These banks are known locally as 'Roman Graves' and some have been dug into with, as far as can be ascertained, no finds made. As stated, one of the earthworks is apparently later than the hollow-way it overlaps (presumably Medieval or later), and another overlays a linear ditch (NZ 12 SW 28), putatively prehistoric. This evidence, together with their somewhat sharp profile, indicates a fairly recent date; their proximity to the disused coal shaft may suggest an association, but no similar structures have been recognised in the vicinity of any other shafts. An alternative explanation may be that the association is with the old trackway running through the group, itself undatable except that it is earlier than the tramway embankments to the east and west and later than the linear ditch (NZ 12 SW 28). Superficially the planform of the internal banks resemble stalls for cattle or horses, but in the final analysis the function of these structures cannot be ascertained. (1)

Five small square enclosures are visible as earthworks on air photographs and lidar, centred at NZ 1220 2496. Of probable post medieval date, the enclosures are 'C'-shaped with an open north face. They meaure between 10m and 12m across. The internal comb-like elements were only slightly visible on the aerial sources and were no mapped. Their function is uncertain, though they may be associated with industrial activity on Cockfield Fell. One of the enclosures appears to overlie an earlier sinuous boundary (UID 873995). The earthworks remain extant on the latest 2015 vertical photography. These features were mapped and recorded as part of the Stockton and Darlington Railway Heritage Action Zone Aerial Investigation and Mapping project. (3) |
