Actually there are absolutely thousands of these things, as you can imagine when there is a long invasion coast to defend. Protection of these monuments, as I understand it, from working in other parts of the country, has focused upon collections of monuments and supporting groups, for example groups of pillboxes arranged to protect an airfield where the group in substantially intact. I am sure EH will not have forgotten invasion coast defences. Even scheduling cannot stop the sea.
