A roughly circular ditched enclosure of probable later prehistoric to Roman date was visible as a cropmark in the floodplain of the River Clyst on aerial photographs of 1966, north-west of Blue Hayes House, Broad Clyst. The cropmark was on average 2 metres wide and enclosed an area approximately 60 metres in diameter. A possible break in the northern edge of the cropmark might be evidence for an entrance. Linear cropmarks roughly aligned with this break might support the interpretation that the entrance to the enclosure was flanked by antenna like ditches. The enclosure was not noted on any other images available to the survey. Much of this enclosure was obscured, and potentially destroyed, by the construction of Lodge Trading Estate. However, the northern edge, and possible antenna ditches lay beyond the extent of development and further investigation of this area by geophysical survey is recommended.
Many of the aerial photographs consulted by the survey are copies of prints held by the Historic England Archive that duplicate images held by the HER. In some cases these have been recorded as separate sources. This is because variations in the way the prints have been processed could result in images on which archaeological features are visible to a greater or lesser degree.
