NHER 55978 (Monument record) - Rectangular pits of unknown date

The Norfolk Heritage Explorer is a filtered version of the Norfolk HER intended for casual research. Please contact us to consult the full record.

Summary

Two large possible extraction pits of an unknown date were identified as part of a rapid identification survey in 1998 and are seen as earthworks on visualised lidar data. It is possible these feature may relate to post-medieval extraction pits; however the earthworks are not seen on the Tithe map or First or Second Edition Ordnance Survey maps. It is also possible these features may have related to military training and are possibly associated to the group of pits and mounds to the east (NHER 63069) or Cranwich Camp to the south (NHER 25240).

NMP mapping has led to the alteration of the central grid reference of the site from TL 7717 9439 to TL 7726 9444 [1].
Two large possible extraction pits of an unknown date are seen as earthworks on visualised lidar data (S2). To the south of the possible extraction pits there is a small ditch and a mound. It is possible these features may relate to post-medieval extraction pits; however the earthworks are not seen on the Tithe map (S3), or First or Second Edition Ordnance Survey maps (S4-S5). It is also possible these features may have related to military training and are possibly associated to the group of pits and mounds to the east (NHER 63069) or Cranwich Camp to the south (NHER 25240).
