NHER 41620 (Monument record) - Undated post groups in Breydon Water

May-November 2004. Norfolk Rapid Coastal Zone Archaeological Survey.
Inter-tidal survey (Environmental Zone 26), Context 157.
Two groups of posts were found. Both were embedded in estuarine mud, south of the modern sea bank, in-situ. The northern group may have been the exposed part of a wreck.
See assessment report (S1) for further details.
The associated archive has been deposited with the Norwich Castle Museum (NWHCM : 2017.421).

January 2006. Norfolk NMP.
NMP mapping has led to the alteration of the central grid reference of the site from TG 50912 08778 to TG 5092 0878. This reflects the discrepancy between the location of the site on the ground as recorded by GPS (as part of the Norfolk Rapid Coastal Zone Assessment Survey, see above) and the locational data achieved through aerial photograph rectification.

Two possible sub-circular structures are visible on aerial photographs (S2), at approximately TG 5092 0878 and TG 5093 0877. These are almost certainly the same structures as the post groups described above, the northernmost of which was interpreted as a possible wreck. On the aerial photographs both structures have a boat-like shape, and they could both be wrecks, perhaps placed here to revet the riverbank (compare NHER 41817 on the southern bank of Breydon Water, for example). A third wreck (NHER 27438) lies approximately 15m to their northeast.
