The Château of Val-Duchesse is a former priory owned by the Belgian Royal Trust. The priory for women was founded in 1262 by Adelaide of Burgundy, Duchess of Brabant, widow of Henry III, Duke of Brabant. 'Duchess Adelaide' gave her name to the place Val Duchesse or Hertoginnedal. It was the first priory for women in the Low Countries that followed the rule of Saint Dominic and was generously donated by Aleydis and other noble ladies. According to her wish Aleydis' heart was interred at a mausoleum today disappeared.
The priory further flourished and gained considerable wealth thanks to the generous gifts of numerous royal persons and noble families. In 1650 a wall was erected to protect the diverse edifices of the priory. The present-day château was built as a residence for the prioress in 1780.
Château of Val-Duchesse played an important role as a venue for negotiations in Belgian and European politics after World War II. In 1956, Paul Henri Spaak lead the Intergovernmental Conference on the Common Market and Euratom at the château, which prepared the Treaties of Rome in 1957 and the foundation of the European Economic Community and Euratom in 1958. The first formal meeting of the Hallstein Commission, the first European Commission, under the presidency of Walter Hallstein, was held on 16 January 1958 at the château.
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.
