BELGIUM, Wis. — A new traveling exhibition on the history of the Luxembourgish language is making its worldwide debut this weekend in Belgium, Wisconsin, coinciding with the community's annual celebration of Luxembourgish-American heritage. The exhibition, on display through Sunday at the Luxembourg American Cultural Center, arrives as thousands gather in Belgium for Luxembourg Fest, a weekend of food, imported beverages and community. This year's event carries a particular focus on language — the thread that connects Luxembourg's multilingual culture to its American descendants.
