In 1633 the rather dilapidated structure was acquired by Ulysses von Salis, a member of the Salis-Soglio family, who adopted the name Salis-Marschlins. He had made his fortune as a French French "Maréchal de camp". Two years later he began renovating the castle and turned it from a more military fortification into an elegant house with a french garden. In 1771 the bell tower on the chapel was added. From 1771 until 1777 the castle became a philanthropinist school. Later, it was a tobacco factory and a silk spinning mill. After the French invasion of Switzerland the castle became an army camp. A total of about 10,000 soldiers and 3,000 horse passed through the castle between March 1799 and December 1800.
