MSO6836 - Chains Barrow (Monument)
Please read the caveat document.
Type and Period (1)
[SS 73454190] Chains Barrow (NR)  Chains Barrow (Exmoor No. 2) is 25 paces in diameter and 6 feet high: there is an Ordnance Survey triangulation pillar on top. Visited by Grinsell 8th Sept 1959. It is known as Cheyne Barrow in 1653.  Scheduled.  A large bowl barrow apparently undisturbed except by the OS trig pillar. See GP AO/65/129/3 Published survey (1/2500) revised.  No change. Surveyed at 1:2500 on PFD.  This or Exmoor 3 (MSO6837) may have been called Exaborough in the 17th Century.  SS 73457 41904. Chains Barrow is prominently situated in an area of grassland on the summit of The Chains ridge about 485 metres above sea level. There are panoramic views; to the north-west are the Chapman, Longstone and Wood Barrows, to the east Alderman's Barrow and Dunkery Beacon. A triangulation pillar is set into the summit of the barrow, slightly southwest of its centre and the base is eroded to a depth of about 0.2 metres into the barrow. The barrow is evident as a turf covered, flat topped earth and stone mound of 1.7 metres maximum height and varying in overall diameter from 23.6 metres north to south to 24.8 metres east to west. Its sides are badly eroded in places probably by sheep. There is a distinct change of profile at the edge of the flat top which is some 15.5 metres in diameter. Although there is no documentary evidence for excavation the uneven surface of the summit area suggests spoil may have been backfilled and consolidated to support the trig pillar. There are traces of a surrounding ditch, about 2 metres wide and 0.2 metres in maximum depth, evidenced by a shallow rush-filled hollow around the periphery. The barrow is a Scheduled Monument and is surrounded by peat cuttings which have come close to the ditch on the south-west side. It has been enclosed by a fence to protect it from sheep and cattle however this is too close to the rim of the barrow, actually encroaching on the outer lip of the ditch, and it is causing an erroneous edge to the feature, especially around the south arc. Surveyed at 1:2500.  The Chains Barrow is clearly visible on aerial photographs; however, the surrounding ditch cannot be discerned as it lies in an area of post medieval drainage and peat cutting, which appears to have obscured the profile. [9,10] The barrow is used as a standing place for cattle which has resulted in the erosion of turf and subsoil.  The barrow is 2 metres high and 28 metres across. It is rather eroded round the base of the trig point.  A grass-covered circular flat-topped mound with an uneven surface about 27 metres in diameter and about 2 metres high. Roughly in the centre of the mound is an Ordnance Survey triangulation pillar sitting on a concrete base. There are shallow hollows on the east side of the mound up to 5 metres long, 5 metres wide and 0.25 metres deep, which do not appear to be recent. A fence has been erected around the base of the mound to protect it but this has caused a well-worn (up to 0.25 metres deep) path to develop around the fence, particularly adjacent to the stile in the southwest corner. A rush filled ditch about 1.1 metres wide and 0.05 to 0.1 metres deep runs around the outside of the mound about 1 to 1.5 metres away from the fence.  The Scheduled Monument Condition Assessment of 2009 gave the site a survival score of 3.  The site was surveyed in April 2015 as part of the 2015 Exmoor Scheduled Monument Condition Assessment. It was given a survival score of 3.
