NHER 54704 (Cropmark and Earthwork record) - Earthworks of a possible medieval moat and/or fishponds and a low platform

April 2012. Norfolk NMP.
The earthworks of the remains of a possible medieval moat and/or fishpond, with associated boundaries and a large low platform, are visible on aerial photographs (S1-S2) at High Common Cottage (NHER 18441) and High House Farm (NHER 19482), Wreningham. The site is centred on TM 1439 9938.
The possible moat is located at TM 1439 9938 and is in part depicted on the Ordnance Survey Second Edition map (S3). The broad drains appear to form three arms of a possible square moat, with a possible conjoined oblong fishpond to the north. Another angular and elongated pond, also on the Ordnance Survey Second Edition map, has also been mapped to the northwest. High Common Cottages (NHER 18441) is thought to date to the early sixteenth century and may have originated from an open hall house. It is therefore possible that this moat and/or fishponds are associated with this hall house. To the immediate north of High House Farm is a large low mound, partly surrounded by a ditch (S2). Whilst it is possible that this slightly raised area merely represents a former extension of the woodland depicted to the immediate south on the Ordnance Survey Second Edition map (S3), it is also possible that this relates to a former area of medieval settlement activity, predating the construction of the sixteenth century High House Farm (NHER 19482). Fieldwaking across the field containing this possible platform revealed medieval pottery, including material dating to the 13th-14th century (NHER 54073).

The sections of possible earthwork medieval moat (see above) are visible on visualised lidar data from a survey flown in 2021 (S4). As the survey was flown relatively recently, it is likely that the features still survive as earthworks. The possible pond centred at TM 1432 9942 also visible on S4.
