Traces of this castle can be found in the archives dating back to 1315, when it was under the jurisdiction of the lord of Saint Geoirs. A remarkably well-preserved tower still remains.

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.

Unique in the world, the Palais Idéal has inspired artists for over a century. Independent of any artistic movement, built without any architectural rules, the Palais Idéal was admired by the Surrealists. In 1969, it was classified as a Historic Monument by André Malraux, then Minister of Culture, as a work of naive art.
