NHER 27405 (Monument record) - World War Two air raid shelters

June 2005. Norfolk NMP.
Three World War Two air raid shelters are visible as extant structures on wartime aerial photographs (S1), (S2) and (S3), centred around TG 5232 0966. They surround a factory or other industrial building and were presumably provided for its workers. They are first visible on photographs taken in March 1944 (S1). The height of the shelters, which appear to have been covered in earth, suggests that they were surface shelters or only slightly sunken. The two to the south of the factory building have a single entrance in their long side, each protected by a blast wall. Square structures visible in the roof of each shelter mark probable ventilation shafts. The northernmost shelter consists of a concrete or masonry structure which is visible without its earth covering on photographs taken in 1945 (S3). It has an entrance at its southern corner, and possibly a second at its eastern corner. Modern maps indicate that since the end of the war the factory has been demolished and whole area, including that occupied by the shelters, built over.
