Keramikmuseum Mettlach, Ceramics museum in Mettlach, Germany.

The Keramikmuseum Mettlach, now called Villeroy & Boch Welt, occupies the second floor of a former factory building beside the baroque Old Abbey, opposite the St. Joseph chapel. Its chronological exhibition covers more than 2,000 square metres and begins with pieces from the mid-18th-century predecessor firms. An outlet is on the ground floor.

The museum opened in 1998 as Keravision to mark the 250th anniversary of Villeroy & Boch. It was established to document and share the company's ceramic manufacturing heritage with the public.

The collection displays tableware, tiles, and decorative objects from different periods that shaped daily life across generations. Visitors can see how ceramics were used in homes and kitchens, and what roles these pieces played in everyday routines.

The museum reopened in January 2025 as the Villeroy & Boch Welt after renovation under the Mettlach 2.0 site development project. The exhibition is on the second floor of a former factory building opposite the St. Joseph chapel, next to the Old Abbey; an outlet occupies the ground floor.

The exhibition includes the interior of a historic milk shop, which served as the visitor cafe before the 2025 redesign. It now stands as a display piece among the ceramics, showing a former use of the space.
