Château of Val-Duchesse
The Château of Val-Duchesse (French: Château de Val-Duchesse, Dutch: Kasteel van Hertoginnedal) is a former priory situated in the municipality of Auderghem in the Brussels Capital Region of Belgium. The château is owned by the Belgian Royal Trust.
It played an important role as a venue for negotiations in Belgian and European politics after World War II. In 1956, Paul Henri Spaak led 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.
More recently, it has twice hosted the Belgo-British Conference, in 2002 and 2006.
History
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 (both meaning Valley of the Duchess). According to the legend Aleydis was inspired by Saint Thomas of Aquin who is said to have been a guest at Val Duchesse. 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.
