History+
The origins of Mühlwang Castle date back to 1305, when it was first mentioned as the ancestral seat of the Mühlwanger family. They were retainers of the Lords of Ort. After the Mühlwangers died out around 1500, ownership changed hands multiple times. In the 16th century, under the Lords of Grünpichl, it was converted from a castle into the present-day palace. Mühlwang belonged to various noble families and personalities, including the Zollner, Hofmann von Grünpichl, and Schmidttauer.
