The idyllic town of Vianden is perhaps best known for its historic castle. Built to defend the town's commanding position in the Our Valley, the castle was constructed between the 11th and 14th centuries, and combined Romanesque and Gothic styles. Set on a rocky promontory, the castle served as the seat of the Counts of Vianden, who were eventual ancestors of the Dutch House of Orange. With relative stability, the town developed and prospered as a centre for many skilled trades.
Eventually the castle was sold off, and in the 18th century - after the combination of a fire, an earthquake and general neglect - it fell into ruin. The castle finally passed into the possession of the state in the 20th century, who took responsibility for an extensive restoration. This project was a great success and, today, many of the castle's original features have been lovingly preserved, along with surviving furniture and decorations from when the Counts of Vianden last inhabited it.
