NHER 55981 (Monument record) - Probable post medieval extraction pit

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

A probable post-medieval extraction pit was identified as an earthwork by a Rapid Earthwork Identification Survey. It is depicted on a late 19th century map, and is also visible as an earthwork on visualised lidar data. As the lidar survey was flown relatively recently, it is probable that the earthwork still survives.

Full Description

February 1998. Walkover Survey.
Rapid Earthwork Identification Survey (Compartment 1022).
A large pit was observed during the survey 30m in diameter and 4m deep and a pit is shown in this location on the 6 inch 1st edition map (1879-1886). The lack of evidence of flint mining could suggest that this is a marl pit rather than a flint mine.
See report (S1) for further details.
S. Howard (HES), 16 August 2011. Amended by P. Watkins (HES), 18 August 2015.

This pit is the probable source of a handaxe that was found at "Mundford Breck gravel pit" in 1917.
See NHER 58794 for further details.

May 2020. Breckland National Mapping Programme.
The pit described above is visible as an earthwork on visualised lidar data (S2). As suggested above, it is probably a post-medieval extraction pit. As the lidar survey was flown relatively recently, it is probable that the earthwork still survives.
The mapped extent of this record has been refined [1].
