History+
The first documented mention of the Schwarzenstein family dates back to 1348. The Stecke family took over in 1454, followed by the Amelong in 1468, and the Mumm family, who later called themselves Mumm von Schwarzenstein, from 1544. After the Schwarzenstein family died out in 1713, Baron Johann Sigismund von Heiden acquired the estates in 1716. In 1729, Schwarzenstein passed to Baron Johann Sigismund von Strünkede through marriage. In 1776, the property was sold from the bankruptcy estate of the Strünkede possessions to the widow Löhr from Wesel, marking the end of its eligibility for the Landtag. In 1849, the Protestant pastor Schneider from Wesel inherited the castle, followed by his brother-in-law Jodocus Albertus Casparus Eichelberg. Between 1889 and 1890, the original building was demolished, with only the tower remaining.
