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 190m west of Hudnalls 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, will contain environmental evidence in the form of organic remains which will relate both to the Dyke and the landscape in which it was constructed. The bank will also contain evidence relating to the methods of construction of the monument and the building materials used.

Details

The monument includes the buried and earthwork remains of Offa's Dyke, 190m west of Hudnalls Farm. Offa's Dyke generally consists of a bank up to 3.5m high with an intermittent ditch to the west and quarry ditches 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 western lip of the ditch. In this section the Dyke runs for some 204m and is visible as a bank with quarries to the east. The bank is about 8m wide and stands to between 1m and 1.5m high on its eastern face, its western face having been removed by the construction of the roadway to the west. The quarries cover an area between 2m and 6m wide and are up to 2m deep. At the southern end of the section, a trackway marks the line of the bank, which is no longer visible, having become worn away over time, but which will survive as buried features. At this scale the Ordnance Survey depiction for this section of the Dyke shows its southern half being overlain by a road. However, on the ground this feature is in fact just a bridleway track lying on the western side of the Dyke. All wooden fence posts, gate posts and stone walls are excluded from the scheduling, although the ground beneath these features is included.
