After the gruesome murder of the last owner, Baroness Thérèse Ernst de Bunswyck, the municipality purchased part of the estate, including the castle, which now serves as Boutersem's town hall. Other lots went to different owners, so the heritage's unity is somewhat lost, with several buildings besides the castle itself. However, there's much more than meets the eye.

The castle's core dates back to 1718, modified several times during the 19th century, and eclectically renovated after 1922; the castle and its outbuildings are surrounded by a 16.5-hectare park, originally a high courtyard with a watermill and mill pond; a classic 18th-century valley floor site, redeveloped in an early landscape style around 1830-1835; redeveloped around 1900 in a late landscape style; municipally owned since 1980; ice and vegetable cellars, numerous old trees.

The veneration of Saint Hubert in Tervuren, the presumed place of death of the patron saint of hunters, dates back to at least the 16th century and is probably even older. Every year on the last Sunday in October, an open-air mass is celebrated there in honor of Saint Hubert, and horses and dogs are blessed to protect them from running amok.

The watermill at Arenberg Castle was probably rebuilt around 1636 on a watermill site known before 1286, which was then equipped with two waterwheels. Major repairs were carried out on the locks around 1722-23 and 1733-35, and images of the mill also indicate modifications to the mill building in the 18th century. Around 1875, the watermill underwent a facade restoration and extension according to the then prevailing views, under the direction of architect Claes. At the same time (1870-80), the mill was equipped with a new bluestone lock and two wooden waterwheels. The waterwheels were replaced by metal wheels at the end of the 19th century, and the locks were also modified in the early 20th century. In 1940, the mill was demolished and the mill was converted into a drawing room; externally the mill was preserved, as well as the lock and the two water wheels.

The first mention of a castle dates from 1371 when it was a heavy keep built by Rasse de Grez, also known as Raes van Graven, a knight who lived from 1368 to 1450 and was lord of Heverlee, Vaalbeek, Bertem, Blanden, Malève and Terbruggen, among other things. The castle was demolished and the domain was ceded to the Croys (family of Croÿ) in 1446. During the first half of the sixteenth century, the reconstruction of the castle was restarted under Guillaume II de Croÿ (Willem II van Croÿ). His successor and nephew, Philip II van Croÿ, had it completed and finished, including a moat. He also had the park laid out and the avenue to Leuven extended. After the death of Charles III of Croÿ in 1612, the castle went via his sister, Anna, to the Dukes of Arenberg who lived there until the First World War. In 1920 the university acquired the domain.

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/
