First recorded in the 14th Century, Schloss Heimhausen was the residence of the Chancellor of Landshut, Dr. Wolfgang Viespeck, who was elevated to the Reichsadel by Duke Albrecht V of Bavaria. The castle was remodelled as a pleasure pavillion in the style of an Italian Villa by Giovanni Antonio Viscardi between 1689 and 1694. It was further extended in 1747/48 when Count Karl Ferdinand Maria commissioned Franois Cuvills the elder to supply the designs.
