Vianden is a small town in northeastern Luxembourg, set in a narrow valley of the Our river near the German border. It is dominated by Vianden Castle, one of the largest fortified castles west of the Rhine, perched on a rocky promontory above the town. The castle dates from the 11th to 14th centuries and has been extensively restored — the interior is open to visitors and the views over the valley are excellent. A chairlift from the town centre takes you to the hilltop above for an even wider panorama.
Victor Hugo lived in Vianden during his exile from France, and his former house on the main street is now a small museum. The Our Valley walking trails in the forested hills above town are among the best in Luxembourg.
The surrounding countryside is some of the most scenic in Luxembourg. A few kilometres north of town, the Vianden Pumped Storage Plant — one of the largest in Europe — can be visited and is surprisingly interesting. Vianden is 40km northeast of Luxembourg City and easy to visit as a day trip.
