Kasteel Sint-Anna

Auderghem, Belgium, Belgium

---

Kasteel Sint‑Anna (Château Sainte‑Anne) is a neoclassical château in Auderghem, on the eastern edge of Brussels, built in 1902 by textile merchant Charles Waucquez on the site of an earlier residence that had been owned, among others, by Henri de Brouckère, the first mayor of Auderghem, and which gave the estate its name in connection with the nearby 11th‑ or 12th‑century Romanesque Chapelle Sainte‑Anne.

The present building, designed by architect L. Sauvage, replaced an older 19th‑century structure with two square wings and is situated at Rue du Vieux Moulin 103, in the perspective of Avenue de Waha, close to the edge of the Soignes forest and the neighbouring domain of Val Duchesse.

In 1959 the Belgian State acquired the estate, and in 1961 it became the headquarters of the Royal International Club Château Sainte‑Anne, which now uses the château and its grounds as a club for social, cultural and sporting activities, offering members tennis courts, swimming pools and a restaurant, while the park and gardens have been landscaped and redesigned over time, notably by Russell Page and Jacques Wirtz, turning the site into a prestigious, club‑linked heritage venue rather than a public museum or open castle.
