The Civil War fieldwork known as The Bulwark is situated to the east of Earith, within a narrow strip of land (the Hundred Foot Washes) which separates the Old and New Bedford Rivers, both of which join the Great River Ouse some 150m to the south.

The Bulwark was strategically placed to command an important river crossing at the western end of the fen causeway which linked Huntingdon to the the Isle of Ely; and to control traffic on both the River Great Ouse, and the earlier of the two artificial navigations (the Old Bedford River), constructed by the engineer Vermuyden in the 1630's. The monument includes the fieldwork with its square inner enclosure, corner bastions, perimeter defences and outworks; and a small steel-domed gun emplacement positioned within the earlier fortifications during World War II.
