Possibly Iron Age or Roman red hill, north-east of Old Hall Marsh Farm, Old Hall Marshes (EHER 11556)

Partially destroyed. The site of a Red Hill with a slight bank and an outer ditch. Red clay and soil and briquetage were found indicating a probable Iron Age and Roman salt works.

'Red hill'. <1> It is recorded on a map produced by Stopes in 1887. <2> Red Hill. [Iron Age/Roman salt industry - see EHER 12107 for a type site]. <3> Aerial photographs show that it had been partially quarried by 1953, lying adjacent to an area of arable. <4> <5> May 1960. Field survey. A 'red-hill' measuring 40.0 m. by 30.0 m. in size, rectangular in plan with a slight bank and an outer ditch round the south side, and raised up to 2.0 m. high above the slope on the north side. Midway on the south side is a causeway across the ditch. Adjoining the north-east corner is a mound composed of red soil and clay, with some fragments of burnt clay or briquetage. <6> Note: The causeway described is probably the earthwork bank recorded in EHER 16707. Feature now ploughed out. <7> August 1995. Site visit. The site appears to lie on a slight knoll within a sub-circular/square enclosure (see EHER 16707) indicated by darker coloured vegetation (grass). <8> September 1998. Site visit. Areas of red soil visible, small fragments of possible briquetage visible (some retained) and one piece of pottery found. Briquetage shown to H. Major of ECC, FAU - quite possibly briquetage but pieces too small for definite identification. Pot sherd shown to H. Walker of ECC, FAU identified as medieval coarse ware of 12th to 14th century date. <9> <10> September 1999. Field survey. During field survey on Old Hall Marshes undertaken by English Heritage (Cambridge Office) during September 1999, this mound was not located, likely to have been destroyed since 1953 by quarrying and ploughing. It is mentioned in the survey report in relation to other red hills located on the marshes. See archive survey report. <11> See also <12> <13>. The red hill can be seen on Google Earth imagery from 2000-2024. <14> Original HER entry merged with NRHE data import. Note: This record should be considered alongside EHER 16707 for nearby earthwork remains of a possible salt production site and which may be associated with the red hill recorded here. Note also that this may be one of the eight red hills recorded by EHER 18963.
