Summary

Lying on the crest of the Gritstone escarpment of Gardom's Edge, partially within the Chatsworth Estate, an enclosure variously interpreted as Neolithic or early Bronze Age, or an Iron Age hillfort or stock enclosure (Hart 1985) and now confirmed by radiocarbon dating as having an Iron Age date. The location offers extensive views in all directions except in the E where it is overlooked by Birchen Edge. The site was first noted in 1942 by the Sheffield Clarion Ramblers, and recorded as `Meg Walls' a `British defence wall' (Ward 1942; 1943). It comprises discontinuous lengths of curved stone wall forming a semi-circle totalling 610m in length, 6-9m wide and 0.3-1.5m high, enclosing approximately 6ha. The walls terminate at the cliff edge with the western extent defined by the scarp. The wall is constructed from large gritstone boulders of a type found locally on the surface, and smaller stones, and was possibly once faced with slabs. Occasional large slabs set vertically, lie towards the outer side of the bank. Excavation has determined three phases of construction with the wall preceded by a line of timber posts, although these are considered to be too shallow to represent a palisade (Barnatt et al. 2000). The wall had an outer kerb and was widened after its original construction to double the width. A charcoal layer overlay the postholes with the stone wall placed on top. Reddening on some of the stones suggests burning took place. A variation in construction methods was observed around the circuit interpreted as evidence for possible gang working (Ainsworth and Barnatt 1998). Six breaks, 2m wide and approximately 40-60m apart have been recorded around the circuit some have been framed with large stones and large earthfast slabs. Four of the entrances are considered original (ibid. 10) and two were later blocked, one with a clearance cairn. A large number of boulders and a large burial cairn lie within the enclosure. It lies within an extensive prehistoric landscape and the enclosure underwent a detailed RCHME topographical survey in 1987 (Cocroft and Jecock 1987) and included in a survey of monuments on Gardom's Edge by RCHME in 1990-1 (Ainsworth and Barnatt, 1998). Further investigations including excavation was carried out between 1995-2000 (Barnatt et al. interim reports). An arc of postholes directly outside the enclosure wall was interpreted as a building, possibly a shrine. It was associated with cobbling and later prehistoric pottery and flintwork was recovered from the features. A small pit containing a human cremation and charcoal deposits was found inside. The site is not recorded on OS mapping.

Investigation History

First discovered in the 1940's and surveyed between the 1940's and 1960's but published posthumously in 1983 (Beswick and Merrills, 1983, 28). The southern extent underwent a detailed RCHME topographical survey in 1987 and was included in a survey of monuments on Gardom's Edge by RCHME in 1990-1. Excavation between 1995-2000

It comprises discontinuous lengths of curved stone wall totalling 610m in length, 6-9m wide and 0.3-1.5m high, enclosing approximately 6ha and forming a semi-circle.

The wall is constructed from large gritstone boulders of a type found locally on the surface, and smaller stones, and was possibly once faced with slabs. Occasional large slabs set vertically lie towards the outer side of the bank. Excavation has determined three phases of construction with the wall preceded by a line of timber posts. The wall had an outer kerb and was widened after its original construction to double the width. Evidence survives for fires inside the wall with the stones placed on top.
