History+
The first mentions of the Rauschenburg manor date back to 1050. In 1317, an official of Bishop Ludwig Landgrave of Hesse from Münster appeared as the first known owner. In 1322, a contract was concluded between the bishops of Cologne and Münster, which provided for the construction of a Lippe bridge near Rauschenburg, reconfirmed in 1444 and 1498. The castle changed hands several times, including Sweder von Rechede (1326) and the von Oer family (1397), who used it as a base for the troops of the Münster diocese. In 1418, Rauschenburg was conquered by the Archbishop of Cologne, Dietrich von Moers. After 1470, it came into the possession of Johann von Hake, who subsequently called himself Johann zu Rauscheburg. His two daughters inherited half of the castle, leading to inheritance disputes that even resulted in a siege by Bishop Bernhard von Raesfeld.
