In 1720 Albrecht Friedrich von Erlach had the castle rebuilt into a baroque country house. He demolished the fortifications and replaced them with parks and gardens. After they sold the castle in 1758, it was a summer residence for the patrician Stürler family for almost two centuries. The Stürlers sold the castle in 1934 and two years later the Society for the Preservation of Jegenstorf Castle ("Verein zur Erhaltung des Schlosses Jegenstorf") converted it into the Museum for Bernese Home Decor. In 1955, management of the castle passed to the Jegenstorf Castle Foundation ("Stiftung Schloss Jegenstorf").
