The Giele Botter nature reserve in the former Schlammefeld iron ore mine is a particularly beautiful place for hiking. It is often wet in the deepest parts, although it was completely dry in the autumn of 2026 after a long, hot summer. The rock is colored orange due to the rusting (oxidation) of the iron in the rock. The excavation is now overgrown mainly with birch trees, but I can imagine that even more biodiversity will emerge here in the coming years.

On the edge of the steelworks, now outside the industrial area, stand the old blast furnaces and new office and administration buildings, including those of universities.
