The Château de Bois-Seigneur-Isaac, a feudal fortress turned into an elegant country house in the 18th century, stands in the heart of the Walloon Brabant countryside, only 25 km south of Brussels.

Behind the château lies a charming French formal garden, extended by an English landscape park, with many remarkable trees and a romantic arched hornbeam walk.

The château has belonged to the Snoy family since 1810. To promote and preserve this architectural ensemble, Baron Bernard Snoy and his wife founded the non-profit association « Les Amis du Château de Bois-Seigneur-Isaac », which opens the château to the public and makes it available for seminars, meetings, business dinners, private concerts, weddings, receptions and other events.
