Halvergate, Great Yarmouth, Norfolk

Oxford Archaeology East were commissioned to carry out an earthwork survey at Halvergate near Great Yarmouth in Norfolk (TG 4898 0789), in advance of habitat improvement works. The site was split into 16 fields (A-P) and surveyed in two phases. The first phase took place on the 24th January 2023 and consisted of a topographic spot height survey carried out through the use of UAVs. This also included a photographic survey of Lockgate Mill. The second phase took place over two days between 31st January to 7th February 2023 and consisted of an interpretive line survey using GNSS systems.
A total of 77 earthwork features were identified with a suspected date range spanning the Late Anglo-Saxon to modern periods. The landscape is covered with natural drainage channels, some of which have been recut and repurposed into enclosures and drainage ditches. There is also evidence for frequent modifications to field boundaries and changes in the alignments of field systems.
Evidence of multiple forms of land use were identified from the earthworks characterised during the survey, including salt extraction, animal husbandry and a possible floated water-meadow.
