About the place

Arenberg Castle anchors the engineering campus in Heverlee, blending Renaissance architecture with modern university laboratories.

The château stands in Heverlee parkland as a Flemish Renaissance complex built by the Croÿ family over an older medieval site and later inherited by the House of Arenberg. Traditional brick walls, sandstone window frames, and corner towers incorporate mixed Gothic and Renaissance elements. After government confiscation prompted by wartime foreign ties, the university acquired the entire estate for a sprawling science campus.
