The town of Wiltz, Luxembourg, located 35 mi/ 56 km northwest of Luxembourg City, offers the country's second-largest museum about the Battle of the Bulge. (The museum's hours are seasonal, so check before you go.)
Another attraction is the baroque castle of the Counts of Wiltz. Its stables house the Luxembourg Beer Museum. Try the local brew, Simon Pils. The stone crosses you see around town commemorate victims of the plague (1300s-1500s) and feudal injustice.
An annual open-air festival of music, theater and dance takes place in July.
