Aremberg Castle was the heart of the eponymous, imperially immediate Barony of Arenberg, whose family still flourishes today in Belgium and South America and has a large fortune.

Following the family's rise up the social strata, the castle complex was expanded over a period of 18 years into a fortress of huge proportions that covered the entire Aremberg around 1670.

The Duke dismissed his garrison troops in 1679 after the Treaty of Nijmegen, a moved which proved fatal.

But a serious accident occurred when an incorrectly planned detonation altered the water supply in the area significantly.

Finally, in 1803, Jean Gaspard Villmart bought the "castle on the Aremberg" and had it demolished in 1809.

[3] Remains from all periods of construction are preserved, such as the moat and bank, bastions of the fortress as well as twelve lime trees in the old castle garden.
