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.

The patronage of this place of worship “Notre-Dame-de-l'Assomption” refers to one of the many memorial or festival days in honor of Mary, Mother of God. This goes back to the festival of her physical assumption into heaven. The (Catholic) Church celebrates this festival annually on August 15th. In the Orthodox churches the feast is called the Dormition of the Virgin Mary. In rural areas of Germany with a predominantly Catholic population, it used to be customary for bundles of herbs to be collected by the population on this special day and blessed in a festive service. This old custom has occasionally survived to this day.
