The Ardennen Offensive Museum is often known as the Battle of the Bulge Museum. It is located in Wiltz Castle. Recalls the 1944 and 1945 Battle of the Bulge with countless genuine papers, images, and battle artifacts.

The Lords of Wiltz erected Wiltz Castle on a rocky cape in the 13th century. It was assaulted multiple times, but the current Renaissance-style fortress was constructed in 1631 by Count John VI of Wiltz. In 1951, the State of Luxembourg purchased the castle grounds for use as an elderly people's home. Wiltz Castle has hosted an international music festival since 1953, bringing internationally renowned musicians and ensembles. Since 1999, the castle's stables have been home to the National Museum of Brewing, which chronicles the history of beer production over the last 6,000 years, with a focus on modern advances in Luxembourg. The little tanning museum tells the story of Wiltz's leather industry, which goes back to 1644. Today, a portion of the castle serves as a campus for European Business University, United Business Institutes, and BBI.

The Jardin de Wiltz, located near the Prabbeli center, is a 2.5-hectare piece of art. This art garden was created and managed by people with disabilities, long-term jobless people, temporary workshop participants, craftspeople, and artists.
