The Royallieu-Compiègne was an German internment and deportation camp located in the north of France in the city of Compiègne, open from June 1941 to August 1944. French resistance fighters and Jews were among some of the prisoners held in this camp. It is estimated that around 40,000 people were deported from the Royallieu-Compiègne camp to other camps in the German territory of the time.
The camp's main function was as a deport base. The main camp that Royallieu-Compiègne deported to was Auschwitz among various other concentration camps. On March 27, 1942, the camp made its first round of Jewish deportations to Auschwitz.
The camp was shut down after the liberation of France. Visitors were not allowed until the opening of the memorial in early 2008.
On February 23, 2008, a memorial to internment and deportation (Mémorial de l'internement et de la déportation Camp de Royallieu) was opened on the site of the former internment and deportation camp of Compiègne.
The memorial site consists of a physical tour of the ground as well as educational tours of the individual rooms and barracks that the grounds consist of. As the site's memorial developed, it came to include a wall of names with those who were recorded as having been detained at the grounds as well as an escape route and a Garden of Remembrance.
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.
