Summary
An undated ring ditch is visible as a cropmark on aerial photographs. Numerous interpretations for such features are possible. It could represent the remains of a Bronze Age round barrow but its topographic location, well below the 5m OD contour, is lower-lying than would be expected of a prehistoric monument. Alternatively, it could have had a more agricultural origin; it might have surrounded a medieval or post medieval mill, for example, or defined a stack stand. Its relationship with the linear cropmarks that surround it (NHER 45088) is unclear. A possible second ring ditch (NHER 45087) lies 130m to the east.

Full description
9 June 1980. NAU air photography.
Positive cropmarks.
Ring ditch.
S. Norton (NAU) 7 August 1982.
September 2006. Norfolk NMP.
NMP mapping has led to the alteration of the central grid reference of the site from TG 4038 1525 to TG 4039 1528.
The ring ditch mentioned above is visible as a cropmark on an aerial photograph (S1). Its date and function are unclear. Its low-lying position (at approximately 1m OD) would be unusual for a Bronze Age round barrow. Given the Broads’ history of fluctuations in relative water levels, for a prehistoric monument to be visible as a cropmark this far below the 5m OD contour line would also be unexpected. A more recent origin related to agriculture is perhaps more likely.
The ring ditch is sub-circular in plan and measures approximately 17m long and 15m wide. It is not known whether the break in the ditch circuit on its northwest side represents a genuine entrance or is a product of the cropmark being masked.
