The castle at Vianden, Luxemburg

Old picture of the early 1980s. The castle was a rather empty affair. It was constructed between the 11th and 14th century. It came into the hands of the house of Nassau in 1417. In 1820 king William I of the Netherlands sold it piece by piece and it fell into disrepair. In 1977 it was restored.
