I've had trouble tracking down the original photographers, but these mostly appear to be pictures of the blast furnaces in Belgium (called things like Haut-Fourneau 4/6/B etc.); here are some other pictures of HFB, of HF4 Charlenoi, and some of HF6 Seraing, by other urban explorers. the first picture is probably cables for an arc furnace, I saw one Instagram post claim it was in Canada but it didn't seem to be the original.
