Vian­den is an extreme­ly pic­turesque town strad­dling both banks of the Riv­er Our. Its fine feu­dal manor, Vian­den Cas­tle (Buerg Veia­nen), dates back to the ninth cen­tu­ry and is unri­valed in the Ardennes and Eifel for its archi­tec­tur­al sig­nif­i­cance. Also of note is the medieval out­er wall encir­cling the town with many impres­sive guard tow­ers.
