This spectacular aerial shot, posted by Darren Bestwick to Facebook group Il’son Bygones, shows the Bennerley Ironworks in 1928.
The image shows the massive plant with the landmark Bennerley Viaduct in the background.
Questions were asked about the plant and its history after the picture was shared.
Fellow Facebook member Steve Hill commented: “Bennerley Ironworks opened in 1874, next to the viaduct.
“The ironworks were in operation for 60 years and closed in 1934. Three main blast furnaces were in operation.”
