The Tellin foundry was the very last one in Belgium to make bells. Guided tours of the site, listed as industrial cultural heritage, present the lost wax technique used at the time, the bridge crane and the reverberatory furnace. 

The bell foundry, built by the Causard family, opened its doors in 1832. Its location, on the stagecoach route between France and Germany, guaranteed its economic success. It closed its doors in 1970 but remains an iconic site.

The tenor bell of the Luxembourg cathedral

The Val des Cloches workshop moulded and casted thousands of bells between 1832 and 1970, using a traditional method. It provided church bells for over 500 Belgian parishes as well as large bells, which can be seen, for example, in the Liège cathedral, the Saint-Paulin church in Trier, the Maredsous Abbey Church, as well as the tenor bell (known as the great bourdon) that hangs in the Luxembourg cathedral.

Practical information

The visit includes a guided tour of the foundry (1 h), the screening of an archive movie presenting the steps in the bell making process (30 mn). The filming was done when the site was still active.

The visit can include, on request, animation sessions for groups of children
