Historic Architecture, Architecture, Interesting Places, Other Buildings And Structures
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 Historic England as probably of post-Roman date, and "a typical Dark Ages boundary earthwork placed astride the Icknield Way". 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). An 730 yards (670 m) stretch south of Cavenham is designated as an SSSI.
