Terril n°3, Mining summit in Ruitz, France.
Terril n°3 is a mining slag heap in Ruitz, formed from waste materials of Pit 6 from the Bruay coal mines and shaped into a cone. The heap stands at approximately 180 meters high and dominates the landscape with its distinctive form.
This slag heap developed during the 20th century as part of Northern Europe's industrial mining expansion. Its formation is linked directly to the growth of one of the continent's largest coal extraction operations.
The site is part of the Nord-Pas-de-Calais mining basin, recognized as a UNESCO World Heritage site in 2012 for representing the region's industrial past. Visitors can observe how the landscape bears witness to this heritage and how the area has become a monument to its own story.
A large staircase with 429 steps leads to the summit, where a viewing platform offers complete 360-degree views. The pathways are well-marked, making it easy for visitors of different abilities to find their way.
The slopes of this slag heap have become a refuge for rare plants and wildlife, transforming industrial waste into a natural habitat. This unexpected greening shows how nature reclaims spaces and creates valuable ecosystems even in human-made structures.
