The Château de Septfontaines (Luxembourgish: Schlass Siwebueren) is located in the Rollingergrund district of Luxembourg City.
[1] The castle was built in 1783–1784 by Jean-François and Pierre-Joseph Boch, who had opened their nearby porcelain factory in 1767, when Luxembourg was part of the Austrian Netherlands.
The brothers had chosen Rollingergrund for their factory, as it offered all that was needed: clay, water and wood for the ovens.
In the dining room hangs a portrait of the Austrian empress Maria Theresa (1717–1780), who had allowed them to build their factory in Rollingergrund and who had freed them from taxation for the first ten years.
Now available for business conferences and receptions, the building is still used by the management, partners and clients of Villeroy & Boch when they are in Luxembourg.
