Fond-de-Gras was one of the most important mining centers in Luxembourg. However the extraction of iron ore ended in 1955. In 1964, a landslide on the Fond-de-Gras – Pétange railway line put an end to all railway activities. A few years later, volunteers commit to run a tourist train with historic steam locomotives. The first “Train 1900” circulated in 1973. A few years later, an old mine is opened again and can be visited thanks to the mining train “Minièresbunn”. Becoming Minett Park Fond-de-Gras, this open-air museum offers many complementary activities whose red thread is iron ore. It includes: Fond-de-Gras, the village of Lasauvage, the old open pit “Giele Botter” and the Celtic oppidum of Titelberg.

Open to the public only from 1 May until the last weekend in September.
