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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
