Situated along the Thames foreshore, these two pillboxes were built around 1940 as part of a huge scheme to build almost 30,000 pillboxes across the country, but especially the south-east. Located about 530 meters apart, each pillbox sits on a corner of the Essex marshes, opposite Greenhithe. Men from the Home Guard would have been sent to these concrete defences to shoot at any German boats coming up the Thames towards London.
Both pillboxes are very similar and are accessed by a sunken entrance which leads you into the main structure which has several loop holes looking out across both the water and sea wall. The pillbox furthest west still has the gun mount in situ and metal brackets on the wall for shutters.
Walking to these remains takes you along a public footpath, past some current and former industrial remains and a selection of graffiti covered sea walls.
