Castles in Luxembourg

Luxembourg is one of Europe's most castle-dense countries — a small nation whose strategic position at the crossroads of France, Germany and Belgium made every hilltop a fortress. Vianden Castle, perched above the Our River valley on its rocky spur, is one of the most impressive Romanesque-Gothic castles in western Europe. The Mullerthal region alone contains the ruins of a dozen medieval fortresses.
