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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
