Kasteel van Huldenberg is a neoclassical castle in Huldenberg, Belgium, with roots tracing to medieval fortifications that were reconstructed around 1820 following earlier destructions. The castle features manicured grounds with picturesque ponds and waterfall elements, notable for early horticultural innovation when gardener Felix Sohie pioneered modern glass-cultivation techniques for grapes in the 1860s. Privately owned and not open to the public, the castle remains an important landmark in the Flemish landscape, representing the transformation of medieval military architecture into 19th-century neoclassical elegance and a site of agricultural innovation.
