Black Ditches is an earthwork close to the village of Cavenham of Suffolk, and part of it is a biological Site of Special Scientific Interest (SSSI). The earthwork is 4.5 miles long between the River Lark at Lackford and the Icknield Way. It is described by the Suffolk Historic Environment Record as having no direct dating evidence but "by analogy with other linear earthworks in the region it is usually assumed to be post Roman".[2]
Two sections of ditch remain visible, one to the north-east of the village and one to the south-east, covering a total of 4.5 miles (7.2 km).[3][4] An 730 yards (670 m) stretch south of Cavenham is designated as an SSSI.[1][5] Access to the Black Ditches is limited, with no public right of way.
