Monument record ELV 121 - Cropmarks of a polygonal enclosure, associated tracks and boundaries of possible prehistoric and/or Late Iron Age date

January 2018. 'Brecks from Above' and Breckland National Mapping Programme.
The cropmarks of a polygonal enclosure and associated tracks and boundaries of possible prehistoric and/or Late Iron Age date were tentatively identified on aerial photographs (S1). The site is located to the east of an area of Late Iron Age fields and boundaries, and early to mid Roman trackways and boundaries excavated in advance of the A11 Fiveways to Thetford Improvement Scheme (S2); Area 11/ELV 086).
The enclosure is D-shaped and measures approximately 52m bv 48m and has a trackway along one side. It is feasible that the enclosure could be Later Iron Age in date and contemporary with some of the excavated cropmarks to the west. However the trackways and more rectilinear elements of the site are also aligned the same as the early and mid Roman tracks and boundaries.
The presence of dense periglacial ‘patterned ground’ cropmarks on all the available aerial photographs of this site, meant that confident identification of the cropmarks as archaeological is hard and it is feasible that some or even all of the cropmarks are of natural origin. Additional possible cropmarks may be visible, but were omitted from the mapping.
