A long fragmentary linear cropmark has been identified in fields to the north of Acol. This feature was recorded from aerial photographs taken by the Royal Commission on the Historic Monument of England as part of a project to identify and classify cropmarks across Kent. The cropmark runs for at least 1km and appears to be associated with a number of enclosures and ring ditches in the area. Site identified during transcription of features recorded on air photographs.

The cropmark remains of this linear boundary (described by 1 above) is visible on aerial photographs HEA 29751/20 29-JUN-2015,HEA 29844/17 20-APR-2016, NMR 2137/14 28-JUN-1983, NMR 3115/140 02-JUL-1986 and EARTH.GOOGLE.COM 07/2013. ACCESSED 08-APR-2024. The boundary is defined by a single sinuous ditch which extends from a multi-phase enclosure complex in the west (TR36NW 46) Which encloses an earlier barrow cemetery of Bronze Age and Early medieval barrows. The boundary has at least two funnel enclosures into open areas to the north and a third entrance at the eastern end (between Acol Hill Farm and Acol) Where it appears to be associated with a second settlement (TR 36 NW 156). Thislinear and associated enclosures have been mapped as part of the Historic England Thanet Landscape Mapping Project 2024 (2-6).
