PRN 13006 Near Ash Cottage at the junction of Gateroom Lane and Gold Fen Dike Bank there are field ditches visible as dykes in pasture. Photograph by P. Everson. {1}{2} The earthwork remains of medieval dylings and an early flood defence bank can be found in the fenland 2.2km north-east of St Mary and St Nicholas' church. The dylings are adjacent to the remains of the flood defence bank, which is the predecessor of the present day Gold Fen Dike Bank. The dylings consist of parallel field strips aligned north-west to south-east, separated by narrow ditches up to 0.5m deep. The strips are about 100m in length, varying in width between 20m and 50m, and cover an area 200m in width. Some of the strips have shallow depressions, which mark the sites of former ponds, and near the centre of the monument is a water-filled pond of later date. The rectangular area occupied by the strips is bounded on each long side by a linear bank between 3m and 5m wide, running at right angles to the strips, and the entire field system is surrounded by a ditch 2m in width. Next to the north-western side of the field system, and aligned with it south-west to north-east, is a broad bank cut along the middle by a narrow ditch. This represents the remains of an early flood defence bank, thought to have originated in the late Anglo-Saxon period to prevent flooding by upland waters from the north-west. The alignment of this bank is followed by the present-day Gold Fen Dike Bank. {3} All modern fences and gates are excluded from the scheduling, although the ground beneath them is included. {3}
