July 2010. Norfolk NMP.
The possible ring ditch and two curvilinear features are visible on aerial photographs (S1)-(S4). The ring ditch is centred on TG 1909 0498, and measures between 25m and 28m in external diameter. It exhibits a possible entrance at TG 1911 0497, which measures 4.3m in width.
Two concentric curvilinear ditches are also visible centred on TG 1903 0509, however they may relate to geological rather than archaeological features.

March 2013. Geophysical Survey. Sectors 8 and 9.
A detailed magnetometer survey was carried out over three areas, encompassing approximately 44 hectares of land in total, in advance of development. Sectors 8 and 9 of this survey were comprised of three fields to the east of the A47 and south of Cantley Lane.
The only features of possible archaeological origin are several weak linear anomalies located in the centre of the surveyed area that appear to broadly correspond to cropmarks of two concentric curvilinear ditches identified in 1994 and 2010 (see above). However, it had been previously stated that these cropmarks could be geological in origin and the magnetic trends have been described as vague with equal possibility of a geological or archaeological origin.
No evidence of the possible ring ditch within this field was recorded. However, magnetic responses in this area may have been masked by the presence of an electricity pylon in the immediate vicinity and underlying geological variation noted throughout the survey area.
A small number of weak parallel linear trends within the data are believed to have been caused by modern agricultural activity.

September 2018. Trial Trenching.
Evaluation of proposed development site.
Unfortunately it was not possible to excavate a trench on the site of the ring-ditch.
It is possible that one of the ditches exposed in the northernmost trench corresponded with one of the other linear cropmarks recorded in this field, although in most cases the trenches were poorly positioned in relation to the cropmark features. The excavated ditch produced a single scap of posssible post-medieval brick or tile.
See NHER 63100 and report (S7) for further details.

September-October 2018. Trial Trenching.
Evaluation of part of large proposed development site.
Although two of the trenches had been positioned to target the possible ring-ditch at TG19100498 neither revealed any evidence for associated sub-surface remains. There was also no correspondence between the excavated remains and the various curvilinear cropmarks mapped to the north. This would suggest that the latter were almost certainly geological in origin - which had been suggested as a possibility when they were first mapped (see above).
See report (S8) and NHER 631000 for further details.
