In Sandweiler are buried 10,913 German soldiers who died in the fierce battles of the winter of 1944 and in the spring of 1945 in the Luxembourg-Belgian and the Luxembourg-German border regions. The cemetery was the first after the Second World War that the Volksbund Deutsche Gräberfürsorge (National Association for Tending German War Graves) was able to set up outside of Germany.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
