“Minett Park in Fond-de-Gras” covers an area marked by its extraordinary natural potential with green valleys which had a whole series of mining tunnels piercing its sides. With the railway line linking this valley to the town of Pétange, the iron ore extracted in the Fond-de-Gras could be transported to the steel factories in Luxembourg and abroad. Today, carefully restored vintage carriages take passengers on a real journey through time.
