In 963 AD, Siegfried, the Count of Ardennes, built a fortification that he called Lützelburg which means “Little Castle.” This is how Luxembourg derived its name. Over several centuries, it expanded into three rings of walls with 24 forts and 14 miles of casemates built into rock that housed thousands of soldiers. This view from Bock Promontory shows some of the ruins along the Alzette River.
