Septfontaines, Rollingergrund

The Château de Septfontaines, known locally as Schlass Siwebueren, is a historic residence situated in the Rollingergrund district of Luxembourg City. Constructed between 1783 and 1784, the building was commissioned by brothers Jean-François and Pierre-Joseph Boch to serve as a shared home for their families while they operated a nearby porcelain factory. The architecture reflects this dual-family purpose, featuring a ground floor with communal spaces like the dining room and lounge, while the first floor is divided into two separate sections for private bedrooms. Its design and existence are deeply rooted in the industrial history of the region, specifically the establishment of the porcelain works that would eventually evolve into the renowned Villeroy & Boch brand.

Historically, the castle has witnessed significant changes, including occupation by French troops and a sale in 1914. In 1970, Luitwin von Boch reacquired the property on behalf of Villeroy & Boch, initiating an extensive twelve-year renovation project led by his cousin, Antoine de Schorlemer. Today, the interior serves as a testament to the Boch brothers' success, adorned with porcelain pieces of various shapes and sizes. A notable feature is a portrait of Empress Maria Theresa in the dining room, honoring her role in granting the factory tax exemptions and construction rights during the era of the Austrian Netherlands.

Currently listed as a protected building, the château remains an active asset for Villeroy & Boch, functioning as a venue for business conferences, receptions, and corporate gatherings. It continues to host management, partners, and clients visiting Luxembourg, bridging its industrial heritage with modern commercial use. Although the associated porcelain factory closed in 2010, the castle stands as a preserved monument to the area's manufacturing legacy and architectural evolution.
