These extensive concrete remains lie just North of the current SSI Blast Furnace.
A post war map shows this structure between the Warrenby Slag Works and the Slag and Tarmacadam Works.
To me the layout of rails and concrete blocks suggest a row of storage hoppers which rail waggon could be driven underneath for loading, although i’m yet to find an old picture of what was actually here.
There were some coastal defences in that area, I recall playing in them in the early 70s, are they part of them?
If its these ones http://www.communigate.co.uk/ne/themarsh/phppQ9PLq I think they were a bit further east, but its all way before my time, hopefully someone will remember
There are pictures of the Slag Works at Skinningrove, maybe these were similar.
