Possible Iron Age or Roman red hill, Fobbing Marshes (EHER 48546)

The soilmark of a possible red hill of probable late Iron Age to Roman date was detected using aerial imagery in 2014, and appeared as a 'quiet' geophysical response on a survey undertaken in 2020.

The soilmark of a possible red hill of probable late Iron Age-Roman date with an enclosure. The site was recorded on 2014 aerial photographs as a cropmark with a central area of darker crop surrounded by an enclosure. <1> Google earth photography shows the same site as soil marks. <2> November 2020. Geophysical survey. An elevated area located in the East of the central part of the surveyed area is particularly notable for its ‘quiet’ background response. This is thought to relate to the location of a soil mark of a ‘Red hill’ which has been recorded from aerial photographs. This suggests the area could have been exploited for salt production during the Late Iron Age and Romano-British period, with a strong magnetic response possibly relating to briquetage or settling tanks. However, this area is also visible on first edition OS mapping (1868) <3> as a pond or extraction pit and it is possible that these remains are much later in date. <4>
