History+
The origins of Frauenberg Castle date back to the early 13th century, with stonemason marks indicating its construction during the Romanesque Staufer period between 1220 and 1250. It was first documented on July 1, 1251. Wolfram von Frauenberg is considered the first known lord of the castle, whose red and silver coat of arms later adorned that of the city of Feuerbach. The estate included Botnang and Zazenhausen in addition to Feuerbach. From the late Middle Ages, the castle became a Ganerbenburg, as ownership was divided among several noble families. Around 1390, the robber knights Wilhelm and Peter von Helmstatt used the tower as a dungeon for kidnapped merchants, which prompted Count Eberhard II of Württemberg to confiscate the castle. Although he later returned it as a fief, he secured considerable influence.
