The henge type feature is almost certainly a mill mound. See name Mill Hill to north-west.

Probable cause - geology and not human agency.
D. Edwards (NAU) 18 December 1980.

However the late H Apling records as site of a 'sunk' postmill.

The cropmarks of post medieval post mill are visible on aerial photographs on ‘Mill Hill’, Aldeby (S2). The post mill is visible as a sub-circular ring ditch, 26m external diameter, with a central slot or T-shaped pit, which would have held the post foundations. The external ditches are up to 5m wide and have three clear causeways. This postmill is centred on TM 4543 9331 and is located within an area of rectilinear fields and enclosures (NHER 45026).
