When the French occupied Electoral Mainz on 21 October 1793, Windeck Castle, as an ecclesiastical and noble holding, was seized. The von Bockenheim family emigrated to Austria. Only Katharina Elisabeth von Bockenheim stayed in Heidesheim, where in 1844 she died at the great age of 95. The Windeck was auctioned off sometime in 1802 or 1803 as state property. The new owner was a Wackernheim townsman named Radicke. His widow handed the property on to the Mainz businessmen Reinach and Popp, who in the second fourth of the 19th century kept a tannery there. In the 1860s, the family Krebs acquired the Windeck. Otto Krebs ran a winery in it with an inn. After 1908, beginning with Christmas, the Evangelical parish held its church services in the hall on the ground floor. In 1984, the castle was, as once before, a private home.
