The original castle was built in the 15th century by Willem van Berchem. In 1542, this castle was destroyed by Maarten van Rossum. Jan van Renesse built the current castle and the outbuildings a few years later. The architect was Hendrik Lambrechts. Many important people visited, such as Emperor Charles V, William the Silent and Margaret of Parma. In the following centuries, the castle was plundered several times and used as a residence for warring troops. Finally, it fell into disrepair. In 1793, the upper court and the farm were demolished.
In 1830, the de Renesse family disappeared from the castle: Count Clément de Renesse-Breidbach sold the whole to Viscount Leonard du Bus de Gisignies. He had the service buildings converted into a country house. He also expanded the entire domain and had an English garden laid out in the park. Among other things, the giant sequoias were planted at that time. His son Bernard Amé du Bus de Gisignies and grandson Bernard du Bus de Gisignies continued to manage the domain. Bernard du Bus de Gisignies became mayor of Oostmalle. His daughter Isabelle married Count Maximilien de Renesse-Breidbach in 1896. The castle thus came back into the hands of the de Renesse family.
In 1920, the castle was renovated in Flemish neo-Renaissance style. In 1941, part of the western wing was bombed to pieces by the British. This part was not restored. Later, Count Thierry de Renesse also became mayor of Oostmalle. After his death in 1973, negotiations began on the purchase of the castle by the municipality. In 1983, the municipality bought the castle and part of the domain. The Flemish Region bought the remaining 33 hectares. Since 1982, the castle has been protected as a monument
