Le Château du Lac is best known today as a 5-star hotel. Events are also often organised there and that is why I know it from a professional long-gone past. But the building, whether you call it a castle or rather a glorified villa, it does have a fairly intense past. In the past, the mineral water of Genval was collected and bottled here. Together with the source of Bonne Fontaine, the Château du Lac was the true symbol of Genval-les-Eaux. The Etablissement des Eaux, as it was originally called, was built between 1905 and 1907 by the architect Julien Wendrickx, the future production director of the Compagnie Internationale des Eaux Minérales, to house the collection of sources and the bottling of the mineral water of Genval. After the First World War and the receivership of the companies that managed the Genval site, the castle became the property of an English company before being taken over by the Princes of Merode, who leased the facilities to Schweppes Belgium. The Belgian branch was then managed by John Martin, an English brewer based in Antwerp, who had been importing beers from Great Britain and Ireland to the continent since 1909, including the famous Guinness. He obtained the exclusive production rights for the Schweppes range, which he transferred to Genval in 1952 following the deterioration in the quality of Antwerp's drinking water, which was now pumped into the Albert Canal. Since the divestment of Schweppes in 1988, the John Martin group has further diversified its range, with speciality beers (Timmermans, Gordon, etc.), soft drinks (Orangina) and fruit juices (Looza). After the Schweppes factory moved to Rue du Cerf, the château, now owned by the Martin family, was converted into the five-star Château du Lac Source: https://www.parismatch.be/lifestyle/voyages/2020/08/23/le-lac-de-genval-et-ses-villas-2D3Q25DBTVANBFBV5WXJG3R2NI/
