Anvaing Castle (Château d'Anvaing or Château de Lannoy) is a historic residence in Frasnes-lez-Anvaing. The site has been occupied by a castle since the time of the First Crusade. The first known reference dates from 1127. There is little documentation of the buildings on the site however until the reconstructions of 1561 and 1800. The owners were apparently the Roubaix family, judging from the arms on an early part of the building, and later the de Lannoy family whose descendants still own it. Stéphanie de Lannoy, Hereditary Grand Duchess of Luxembourg, grew up in the castle.
The castle is chiefly notable as the place in which the Belgian capitulation was signed on 28 May 1940, during the Battle of the Lys. At the time, it served as the headquarters of the German 6th Army. The Belgian plenipotentiaries arrived at the castle at 9:35 am. Shortly afterwards, General Olivier Derousseaux and Commandant Liagre were received by General Walther von Reichenau and Major-General Friedrich Paulus. Discussions took place in the dining room. At 10:00 am, the surrender became effective. The document was read and signed. In celebration, a German officer fired a gunshot into the ceiling which is still present.
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.
