The field name Brustelberg on the slope of the Betzenberg refers to the fact that there was a medieval castle here, which was inhabited until 1670 and then fell into decay. After the death of the last owner, the childless Junker Phillip Grempp von Freudenstein, the castle became the property of Württemberg in 1641, Friedrich von Ragowitz received it as a Kunkel loan. His widow was the last inhabitant of the castle, when she died in 1670 the castle was already in a state of great decay.
