Beersel, Belgium
Beersel is a municipality in the Flemish Brabant province of Belgium, immediately south-west of Brussels. It is known for its medieval castle, green countryside, historic villages, and especially its connection with lambic, gueuze, and kriek beers. The municipality is part of the Dutch-speaking Flemish Region.
Location
Beersel lies roughly 12 km south-west of central Brussels, making it part of the green suburban belt around the Belgian capital. It occupies a transition zone between the urban environment of Brussels and the more rural landscapes of Flemish Brabant.
The municipality borders the Brussels-Capital Region and several Flemish and Walloon municipalities. Historically and geographically, it is associated with the Senne (Zenne) valley, the Flemish Rand, and the Brabant countryside.
The municipality consists of five main sections:
- Beersel
- Alsemberg
- Dworp
- Huizingen
- Lot
The present municipality was created through Belgium’s municipal reorganization in 1977.
Population
Beersel has experienced steady population growth during the 21st century.
According to the latest available municipal statistics based on Statbel data, Beersel had approximately 26,800 residents on 1 January 2026, with a population density of about 881.5 inhabitants per km².
For comparison:
| Year | Population |
|---|---|
| 2010 | 23,903 |
| 2015 | 24,588 |
| 2020 | 25,343 |
| 2023 | 26,474 |
| 2025 | 26,593 |
| 2026 | 26,800 |
This growth reflects Beersel’s attractive location close to Brussels while retaining a relatively green and semi-rural character.
Beersel Castle
The municipality’s most famous landmark is Beersel Castle, a remarkably well-preserved medieval moated fortress.
The castle was constructed around 1300–1310 under Jean II, Duke of Brabant, as part of the defensive system protecting Brussels. Its architecture includes massive towers, defensive walls, a moat, and other features characteristic of medieval military architecture.
Today it is regarded as one of Belgium’s best-preserved medieval military castles and one of the oldest and most authentic moated castles in Flanders.
The castle subsequently passed through several noble families, including the van Wittem and Arenberg families. At one point, the site suffered neglect, with portions reportedly used as building material elsewhere in Brussels. Restoration later helped preserve its medieval appearance.
Alsemberg
Alsemberg is one of Beersel’s five constituent communities and is particularly important for religious heritage.
Its major landmark is the Gothic Church of Our Lady, which is among the municipality’s notable historic attractions. Tourism authorities highlight it alongside Beersel Castle and the Herisem paper mill as one of the area’s principal heritage sites.
Alsemberg is also home to De Lambiek, the municipality’s famous visitor centre dedicated to Belgian lambic beer.
Lambic Beer Tradition
Beer is arguably Beersel’s second great cultural symbol after its castle.
The municipality is strongly associated with lambic beer, a distinctive Belgian beer traditionally produced through spontaneous fermentation. Lambic is the foundation for famous styles such as:
- Gueuze
- Oude Gueuze
- Kriek
- Oude Kriek
- Faro
Beersel’s tourism authority specifically identifies lambic, Oude Geuze and Oude Kriek as important local specialties, and notes that the municipality has three active producers of artisanal lambic-style beer.
De Lambiek
De Lambiek in Alsemberg functions as a visitor centre dedicated to the history and production of lambic.
Visitors can learn about spontaneous fermentation, ingredients, barrel maturation and the production of gueuze and kriek. The centre also has tasting facilities and a shop selling regional products and lambic beers.
Oud Beersel
The Oud Beersel brewery is another important part of the local beer tradition. According to Visit Flanders, it has been producing lambic beer using traditional methods since 1882.
This makes Beersel particularly interesting for visitors interested in Belgian brewing history.
Nature and Landscape
Despite its proximity to Brussels, Beersel has a notably green landscape.
The municipality lies around the Senne valley and contains:
- forests
- meadows
- agricultural fields
- nature reserves
- wooded valleys
- traditional sunken roads
- walking and cycling routes
The local tourism organization describes Beersel as a green oasis on the southern edge of Brussels.
The landscape makes the municipality popular for walking and cycling, especially for people looking for an escape from the urban environment of Brussels.
Herisem Paper Mill
Another important heritage attraction is the Herisem paper mill, located in the Molenbeek valley.
The former industrial site preserves part of Beersel’s industrial heritage and illustrates the area’s historical connection with paper production and small-scale industry. It is promoted alongside Beersel Castle and the Church of Our Lady in Alsemberg as one of the municipality’s principal heritage attractions.
Huizingen
Huizingen is another constituent section of Beersel and is particularly associated with the Provincial Domain of Huizingen.
The domain provides a large recreational and green environment close to Brussels and is one of the attractions that gives Beersel its combination of nature, leisure and heritage.
Cycling routes around Beersel also connect the area with Huizingen and other attractions in the Brussels green belt.
Culture and Local Food
Beersel’s food culture reflects the broader culinary traditions of Flemish Brabant.
One particularly local product is mandjeskaas, literally “basket cheese,” a traditionally produced fresh cheese associated with the municipality.
Visitors can combine local food with regional beers such as gueuze and kriek, making Beersel an interesting destination for Belgian beer and gastronomy.
Economy
Beersel benefits from its location within the economically important Brussels metropolitan area.
Many residents can commute toward Brussels and other nearby urban centres, while the municipality itself has businesses in sectors including services, retail, hospitality, manufacturing and specialized local production.
Statbel-based data show approximately 2,693 VAT-registered enterprises in 2024, equivalent to about 100.5 enterprises per 1,000 residents.
The brewing and tourism sectors are particularly important to Beersel’s identity even though they represent only part of the broader local economy.
Transportation
Beersel’s proximity to Brussels makes it relatively accessible.
The municipality has railway connections and road links to Brussels and surrounding communities. Beersel railway station is located very close to Beersel Castle; the castle’s tourism information places the station approximately 180 metres from the castle.
Bus services also connect the different parts of the municipality with surrounding communities and Brussels.
For cyclists, Beersel is particularly attractive because established routes connect the municipality with Brussels, Huizingen, the Brussels–Halle Canal and other nearby attractions.
