Monument record HLY 096 - Roman salt production site or 'saltern'.

A Roman salt production site or 'saltern' is visible as a 'red hill' on aerial photographs, centred on TM 35954325 to the south-west of Oxley Marshes in Hollesley parish. The site covers an area of 63m by 44m and is visible as a ring shaped white soilmark with an adjacent red soilmark to the west. It is not clear from the photographs whether the ring shaped soilmark is part of the saltern. (S1-S3) The interpretation of the site as a Roman salt production site was confirmed during a site visit by Linzi Everett of Suffolk County Council Archaeological Service on the 4th March 2004. The site was described as a small spread of red material and briquetage on a slight rise but around this higher area, more red was obviously present but only just being reached and turned by the plough. (S4) The full finds report was not available at the time the report was compiled. (S5)

The cropmarks of possible ditches or channels associated with the previously recorded Roman saltern are visible on aerial photographs (S6-S7). Although it is feasible that these features have been cut into the site in the post-Roman period or alternatively that as the saltern deposit gets increasingly disturbed by the plough, that ditches pre-dating the site are producing a cropmark response.
