Kasteel Sterckshof is a red-brick Flemish Renaissance castle with moats, towers, and gatehouse situated within Rivierenhof Park, Antwerp's largest public green space east of the city center. Originally a 13th-century fortified farmhouse, it was transformed into a Renaissance-style castle in 1524 by merchant Gerard Sterck and later owned by Jesuits before becoming part of the Ter Rivieren estate. Reconstructed in the 1930s based on historical photographs and archaeological findings, the castle showcases distinctive red brickwork and decorative white sandstone architecture protected as a monument since 1994.
