Château Sainte-Anne, Castle in Auderghem, Belgium.

Château Sainte-Anne is a white stone castle built in 1902 by architect Louis Sauvage for Charles Waucquez, set at rue du Vieux Moulin 103 in Auderghem, at the edge of the Soignes forest. Its seven-bay facade rises two levels on a blue-stone basement, with a projecting three-bay centre reached by a wide perron around a blue-stone-edged basin. The ground floor has round-arched bays between pilasters, the upper floor rectangular windows with Ionic pilasters, and a balustraded gallery hides a nearly flat roof.

The château was built in 1902 as a private residence for a wealthy family and reflects the architectural style of its era. In 1961, it became home to an international club and has hosted members from various countries ever since.

The castle functions as a social gathering place where both Belgian and international visitors come together for events and leisure activities. The spaces retain their residential character, creating a distinctive setting for members and guests.

The castle stands at rue du Vieux Moulin 103, at the end of the axis of avenue de Waha, on the edge of the Forêt de Soignes next to Val Duchesse. The grounds are private and run by the Maison Européenne de Val Duchesse, so access is not open to the public. The forecourt is reached on foot around the blue-stone rimmed basin, or by car along the asphalted path.

The five water jets on the terrace steps spring from four dolphins and the mouth of a bearded god crowned with a shell, his head resting on reeds and his hair holding two laurel garlands. The jet falls into a second glazed shell. The central bays of the garden facade step back, isolating the outer bays so they read as towers, each topped by a gable.
