Château de Trois-Fontaines

Château de Trois-Fontaines is a stone fortified residence in Auderghem featuring multiple towers and defensive walls built in vernacular style. The structure sits at the forest edge and displays characteristics typical of medieval strongholds from its period.

The fortification was established in the 15th century and later served as a detention facility for poachers and forest law violators. Eventually its role changed when prisoners were transferred to facilities in Laeken.

The chapel within these walls served as a place of worship, and visitors can still sense the spiritual role it played in daily castle life. The space shows how religious practices were woven into the rhythm of the estate.

The ruins are accessible via Chaussée de Wavre with convenient bus connections nearby. Visitors should prepare for uneven ground and the wooded surroundings.

The building contained four water spouts, though boatmen passing nearby could typically see only three. This visual quirk gave rise to the name by which the site is still known today.
