Maison de Victor Hugo
In 1870, the French novelist Victor Hugo was still living in exile from his country, after openly criticizing the autocratic rule of Napoléon III. The bulk of his 19 years in the wilderness was spent in the Channel Islands, where he wrote his best-known works. But before he finally returned to France, he spent three months in Vianden, and the town has never forgotten it. The Maison de Victor Hugo is set within the house in which he lived, and celebrates his life with photos, documents, tall tales (it is claimed he stopped a house burning down), and other memorabilia. His writings and works are in French, but an excellent free audio guide narrates the story of his home and the objects found here in English, so it's well worth a visit.
