A slag heap is a hill made of waste material from coal mining. If you only pay attention to that definition, a slag heap doesn’t look really appealing. But they are more than just little piles of mine tailings. They are symbols and silent witnesses of almost 300 years of history, areas that promotes the development of the flora and fauna and also real havens of peace. To really understand what they are, what they represent and to realise how much of the past is trapped in them, it is important to climb and explore them.
Passionate about nature and landscape photography, Bénédicte went off to discover these hills scattered in the North of France.
