The faithful trust in the help of the Mother of God – who in France is always venerated under the title “Notre-Dame” (which corresponds to the German name “Our Lady”) – was expressed by the French nun, mystic and Doctor of the Church, Saint Thérèse of Lisieux (religious name Thérèse of the Child Jesus and the Holy Face, 1873 to 1897) as follows: “In trials or difficulties I turn to Mother Mary, whose gaze alone is enough to dispel all fear.”

In 1869, the Marist Brothers purchased the castle and its grounds. They raised the body of the central building by one floor. The castle was then acquired by the city in 1906. In 1914, it became a military hospital and from 1940 to 1960, a modern college. The castle now houses a music school and meeting rooms. Many areas are vacant. The Ministry and the public agency for cultural cooperation (aida) conducted a feasibility study for the establishment of a European Cultural Exchange Center in the building. If you take a walk in the park in the afternoon, you can hear the musicians practicing.
