This castle, actually a mansion, was built from 1759-1761 by Marcel-Gérard Magnée from Liège, who would buy Horn Castle in 1798. Originally it consisted of three separate wings, namely an L-shaped mansion and two service buildings. One of them was demolished at the beginning of the 19th century. The other was extensively renovated in the second half of the 19th century. A farm near the park was demolished and the grounds were added to the park, which was laid out in its current form at the same time and was partly in a formal style, partly in an English landscape style. The mansion is an L-shaped brick building, painted red and with a preserved interior in rococo style. There are still tiled fireplaces, a fireplace with stucco work and a painting by Mr Magnée in the dining room. There is also an octagonal salon with murals by Italian artists. The house also contains a library. The current service buildings that are attached to the mansion form a U-shaped complex and date from the second half of the 19th century. But the wing on the street side, with gate, may have been a transverse barn with a core from the 18th century. The castle is one of the few rococo castles in Belgium.
