The Best Sight in Vianden, The Luxembourg Ardennes

Driving around the last bend into Vianden, you're greeted by a full-length view of Vianden Castle rearing up on the hill, replete with conical spires, crenellation, step gables, and massive bulwarks. The castle was built on Roman foundations at the turn of the first millennium, though its most spectacular portions date from the 11th, 12th, and 15th centuries. Its near-pristine appearance is the result of massive restoration in the 20th century.
