History+
As early as the third quarter of the 16th century, Thumsenreuth Castle resembled its current appearance, as evidenced by a historical map from the Amberg State Archives. Christoph Notthafft, who acquired the castle in 1586, initiated renovations in the same year. He had the building adorned with an oriel window, which still bears his family crest along with the coats of arms of his two wives, Dorothea von Biberern and Martha von Seckendorff. Since 1661, the castle has been continuously owned by the von Lindenfels family, who undertook a restoration between 1992 and 1994.
