Vianden Castle (Luxembourgish: Veianer Schlass [ˈfɑɪ̯ɑnɐ ˈʃlɑs] or (locally) Veiner Schlooss [ˈfɑɪ̯nɐ ˈʃloːs] ; French: Château de Vianden; German: Schloss Vianden), located in Vianden in the north of Luxembourg, is one of the largest fortified castles west of the Rhine. With origins dating from the fourth century as a Roman outpost and the 10th century, the more familiar castle form was built in the Romanesque style from the 11th to 14th centuries. Gothic transformations and trimmings were added at the end of this period. A Renaissance mansion was added in the 17th century but thereafter the castle was allowed to fall into ruins. It has, however, recently been fully restored and is open to visitors. Vianden Castle is widely regarded as the best castle to visit in Luxembourg.
