Karreveld Castle in Sint-Jans-Molenbeek is a Flemish Renaissance castle-farm constructed in the 16th or 17th century and restored between 1952-1958. The name reflects its historical function extracting clay for brick-making in the Maalbeekvallei valley. Now a cultural venue, Karreveld hosts diverse events including Christmas markets, theater festivals, jazz performances, wedding ceremonies, and municipal gatherings. The castle's surrounding park provides a serene urban escape, protected as a heritage monument since 1955.
