Castle Blauwendael in Waasmunster is a striking example of Flemish Neo-Renaissance architecture, built between 1889 and 1890 by renowned architect Jozef De Waele. Featuring distinctive turrets and stepped gables characteristic of the period, the castle stands within a 4.5-hectare English landscape park originally designed in 1820. The castle's interior retains its period styling and architectural integrity. Acquired by the municipality in 1980 and opened to the public in 1981, the estate now hosts cultural events, exhibitions, and serves as a sought-after wedding venue, offering visitors a glimpse into 19th-century Flemish nobility and romantic garden design.
