Built in 1906 in the Lorraine style and operating as a 5-star hotel since 1985, Martin's Château du Lac sits on the shores of Lac de Genval just 20 minutes from Brussels. Its flexible event spaces accommodate celebrations from 10 to 1,000 guests, backed by a 1,500 m² wellness centre and the fine-dining Genval.Les.Bains restaurant.
There is something quietly unlikely about a building that began its life as a thermal spa, became a Schweppes bottling plant, and has spent the last four decades as one of Belgium's most admired château hotels. Martin's Château du Lac has navigated its unusual biography with evident grace: the Lorraine-style architecture of 1906 sits undisturbed on the shores of Lac de Genval, its towers and gabled rooflines reflected in the water as they have been for more than a century.
What the château offers wedding couples today is genuine range — the ability to host ten guests or a thousand, across indoor salons and courtyard gardens that open generously towards the lake. The 1,500 m² wellness centre with its rooftop terrace gives guests somewhere to retreat the morning after. Genval.Les.Bains, the in-house restaurant with its refined French cuisine, provides the culinary backbone. And the proximity to Brussels — twenty minutes by car — means that a countryside feeling need not come at the cost of a city weekend.
