Did you know ?
We normally talk about “the” slag heap, but in fact Blegny-Mine has two, from different periods. The first dates from the period between the First and Second World Wars, while the second started to be built up in 1947. A third slag heap should have been started in the 1970s, as the second had reached its maximum height, but because the site was programmed to close, the management side-stepped having to make this investment by flattening out the second slag heap, which is why it is a strange shape and looks like a simple pile of stones. Hence the reference to “the” slag heap, in the singular.
