Clervaux suffered terribly during World War II. The entire town, including the castle, was reduced to rubble, and its people were thrown into poverty. Although the structures have been lovingly rebuilt and the town is now economically healthy, Clervaux still remembers these desperate times. The World War II Museum, housed within the castle, is a collection of photographs and artifacts from the war and particularly from the events of the Battle of the Bulge that occurred
in and around town.
