Le Fonds Belval - "Massenoire" building

Where? Avenue du Rock'n'Roll, L-4361 Esch-sur-Alzette

An exhibition space like no other.

This special exhibition space takes its name from the heaps of black matter (masse noire in French), which was the compound used to close the tap holes of the blast furnaces that produced industrial metals during the 20th century. Now that the building is no longer the site of industry, Massenoire is used for events related to the industrial heritage of Esch.

FerroForum
The FerroForum was created with the aim of preserving and promoting the cultural and industrial heritage of Esch, as well as showcasing the know-how about the processing of iron and steel into products we use every day. The space, originally restored as part of the Esch 2022 European Capital of Culture programme, is a destination for all those who are curious about how metal objects (things that last) get made. Established as a non-profit association, the FerroForum space is located in the central workshop of the former Arbed Esch-Schifflange ironworks.
