The Minett Park Fond-de-Gras is an open-air museum that includes the Fond-de-Gras, the village of Lasauvage, the former open-cast mine of “Giele Botter” and the Celtic oppidum of Titelberg. Historically, the Fond-de-Gras was one of the most important mining centres in Luxembourg. A few years after the closure of the last mine at the Fond-de-Gras in 1964, a few volunteers worked to preserve part of the railway line with the aim of operating a tourist train on the line. The first such train service ran in 1973.
Today, at the Fond-de-Gras, several historic buildings have been preserved: an electric power station, old grocery store, rolling mill train, railway station and railway sheds, testifying to the mining activity that took place there for nearly a century.
