The landscape in the area north-east of Peterborough, incorporating Borough Fen, Milking Nook and Newborough would have looked very different in the late-Neolithic and Bronze Age to the present agricultural scene. Archaeological investigations have discovered that the landscape contained several bowl barrows and ring ditches, now buried below the surface.
Bowl barrows were part of funeral rituals and contained single or multiple burials. They are common in lowland areas, although Borough Fen is remarkable for the number clustered along the prehistoric fen edge. The majority are approximately 5m in diameter, but the scheduling area around them is much more extensive.
