Cropmarks of a Late Neolithic henge and a henge type monument located in a field on the north side of the Gadsey Brook, at Dairy Farm, Willington. Cropmarks of a bowl barrow are visible 24 metres north of the henge (Monument HOB UID 1229875).
The henge is situated approximately 270m to the north of the brook and has been reduced by ploughing and is not visible at ground level. However, it is visible as cropmarks which have been recorded by aerial photography on numerous occasions since 1970, and also has been clearly identified by a geophysical survey undertaken in 2004. The henge is defined by an outer circular ditch, about 37m in diameter and an inner ditch of about 22m in diameter. The outer ditch is truncated by a pipe trench on its east side which also cuts through the barrow to the north Monument HOB UID 1229875).
The henge type monument is situated about 24 metres to the east of the henge and has been clearly identified by geophysical survey undertaken in 2004 and by trial trenching in 2005. It is about 32 metres in diameter, and appears as a single circular ditch measuring about 3.7 metres wide and 1.25 metres deep.
