Reasons for Designation

Offa's Dyke is the longest linear earthwork in Britain, approximately 220km, running from Treuddyn, near Mold, to Sedbury on the Severn estuary. It was constructed towards the end of the eighth century AD by the Mercian king Offa, and is believed to have formed a long-lived territorial, and possibly defensive, boundary between the Saxon kingdom of Mercia and the Welsh kingdoms. The Dyke is not continuous and consists of a number of discrete lengths separated by gaps of up to 23km. It is clear from the nature of certain sections that differences in the scale and character of adjoining portions were the result of separate gangs being employed on different lengths. Where possible, natural topographic features such as slopes or rivers were utilised, and the form of Offa's Dyke is therefore clearly related to the topography. Along most of its length it consists of a bank with a ditch to the west. Excavation has indicated that at least some lengths of the bank had a vertical outer face of either laid stonework or turf revetment. The ditch generally seems to have been used to provide most of the bank material, although there is also evidence in some locations of shallow quarries. In places, a berm divides the bank and ditch, and a counterscarp bank may be present on the lip of the ditch. Offa's Dyke now survives in various states of preservation in the form of earthworks and, where sections have been levelled and infilled, as buried features. Although some sections of the frontier system no longer survive visibly, sufficient evidence does exist for its position to be accurately identified throughout most of its length. In view of its contribution towards the study of early medieval territorial patterns, all sections of Offa's Dyke exhibiting significant archaeological remains are considered worthy of protection.

The section of Offa's Dyke in Worgan's Wood, 800m west of Chase Farm, survives well. The bank will have preserved part of the original ground surface, predating the construction of the monument and, along with the quarries to the north east, will contain environmental evidence in the form of organic remains which will relate both to the Dyke and to the landscape within which it was constructed. The bank will also contain evidence relating to the methods of construction of the Dyke and the building materials used.

Details

The monument includes the buried and earthwork remains of a section of Offa's Dyke, 800m west of Chase Farm. This section of the Dyke is in the care of the Secretary of the State. Offa's Dyke generally consists of a bank up to 3.5m high with an intermittent ditch to the west and quarry pits to the east. In places Offa's Dyke was strengthened by additional earthworks, namely a berm between the bank and ditch, and a counterscarp bank on the lip of the ditch. This 952m long section of the Dyke turns from its usual alignment to run north west-south east. It is visible as a bank with contiguous quarry pits to the north east, from which material was excavated during the construction of the monument. The bank is up to 13m wide at its base and stands to approximately 2m on its south west face and 1.5m on its north east face. The quarries to the north east vary in depth between 0.7m and 1.8m and are between 6m and 8m wide. There is a gap in the line of the monument at Ordnance Survey NGR ST 54579848 which provides access for forestry vehicles, and this is not thought to be an original crossing point through the monument. All fence posts, sign posts and marker posts are excluded from the scheduling, although the ground beneath these features is included.
