Auderghem
Located in the south-eastern part of the region, along the Woluwe valley and at the entrance to the Sonian Forest, it is bordered by Etterbeek, Ixelles, Watermael-Boitsfort, and Woluwe-Saint-Pierre, as well as the Flemish municipalities of Tervuren and Overijse.Despite large roads slicing through and the increasing traffic, the municipality has an environmental advantage, and it has been able to preserve a relatively important part of its natural and historic legacy: the creeks, Rouge Cloître Abbey and its art centre, the Priory of Val-Duchesse, the Château of Three Fountains, the Château Saint-Anne, and St. Anne's Chapel.In 1811, Napoleon decided to reunite the three villages, by imperial decree, into a single administrative entity.In 1956, Paul Henri Spaak lead the Intergovernmental Conference on the Common Market and Euratom at the Château of Val-Duchesse in Auderghem, which prepared the Treaties of Rome in 1957 and the foundation of the European Economic Community and Euratom in 1958.As of 2004[update], the majority of Brussels' Japanese expatriate population lives in Auderghem.
