Also on the German border is Vianden, a quaint and hilly town on the River Our. The two most striking features of the town are its old-world charm and Vianden Castle which stands high above the river. Built between the 11th and 14th centuries, the castle was a prominent home for Luxembourg royalty for hundreds of years before falling into ruin for almost as long.
