NHER 54559 (Monument record) - Undated linear bank and ditch earthworks and possible cropmark of ring ditch

January 2011. Norfolk NMP.
A linear bank and ditch are visible as earthworks on aerial photographs (S1-S2) on land to the south of Castle Street, Thetford.
The site is centred on TL 8775 8289. The linear ditch and bank features are likely to relate to post medieval drainage features, but it is also possible that they are medieval to post medieval field boundaries.
A cropmark of a possible ring ditch is also visible to the north, however this is only visible on one set of photographs, and is likely to be a non-archaeological fungus ring, or possibly a post medieval windmill mound.
The possible ring ditch is centred on TL 8770 8293, and measures 9.5m in external diameter, 7m in internal diameter.
