Auderghem is located to the southeast of the capital, along the Woluwe valley and at the entrance to the Sonian Forest, the municipality has an environmental advantage. Despite large roads slicing through and the increasing traffic, it has been able to preserve a relatively important part of its natural and historic legacy: the creeks, the Abbey of Rouge-Cloître, the Priory of Duchess Dale, the Three Fountains Castle, and the remarkable Chapel of Saint Anne.
