Former feudal fortress which became a country house in the 18th century. Located in Brabant Wallon, 30km from Brussels.

In short:

  • Discover it just 30km south of Brussels,
  • A magnificent residence listed as a Walloon site of exceptional heritage,
  • Guided tours can be organised and the castle can be hired for events.

The park of the Bois-Seigneur-Isaac Château is a landscaped park laid out at the beginning of the 19th century. It is designed around the prospect from the château to the former guard house with its Neo-Gothic windows.

As well as a romantic centuries-old bower, the park also boasts several other remarkable listed trees. A formal garden designed by Dechêne in the early 20th century stretches out behind and parallel to the château.

You can hire the castle with its prestigious setting and different spaces for your professional and private events: weddings, seminars or receptions.
